This study deals with the investigation of flexural stiffness and transverse shear rigidity in the direction of corrugation of the integrated and non-integrated corrugated core sandwich panels with the rectangular core. The non-integrated sandwich panels were reinforced with conventional 2-D fabrics in which resin provides the bond between core and skins. The integrated sandwich panels were reinforced with 3-D weft knitted fabrics in which bonding of the core wall to skins was carried out by combined efforts of knitted loop and resin. Using weft knitting technical capabilities, samples of the integrated and non-integrated structures were manufactured with the uppermost degree of resemblance in terms of geometry and mass. Flexural stiffness and transverse shear rigidity of the structures based on the known and unknown facing modulus of ASTM D7250 standard and Nordstrand–Carlsson methods were calculated. The estimated elastic constants based on unknown facing modulus and the Nordstrand–Carlsson methods were found to be highly compatible. However, the unknown facing modulus method is prone to disclose the statistical significant differences between the elastic constants of the structures with fewer tests. Regarding the unknown facing modulus method, it was found that the flexural stiffness and transverse shear rigidity of the non-integrated structure in the direction of corrugation were higher than those of the integrated structure. Results also indicated that the load-carrying capacity in the direction of corrugation was significantly higher in case of the non-integrated rectangular core structure compared with that of the integrated structure.Get more news about Bh-sandwich Panel Series,you can vist our website!

Sandwich panels are composed of a thick and low-density core which is sandwiched by two thin and stiff skins or face sheets [1, 2]. High specific flexural stiffness and strength are among the main features of sandwich panels. The core can be composed of miscellaneous materials such as foam, honeycomb, and corrugated sheets. Corrugated cores in comparison with foam or honeycomb are superior as far as factors such as shear strength in the transverse direction of corrugation, strength to weight ratio, structural integrity, and fluid storage capacity are concerned. The core geometry in the corrugated core sandwich panels is more than often trapezoidal (hat-type), rectangular, triangular, circular, and sinusoidal [3, 4]. An additional bonding operation using adhesive is used in the production of the laminated composite where core and skins have to be prepared separately. Poor mechanical performance of adhesive, complexity associated with predication, and determination of joints strength as well as small contact surface area between the core and the skins are among the disadvantages associated with the adhesively bonded corrugated core sandwich panels. The stated disadvantages may lead to the poor mechanical performance of the resultant composite structures or their delamination [5,6,7,8,9,10]. Taghizadeh et al. [11] experimental investigation revealed that the delamination of skin–core is the principle damage mechanism that can occur in corrugated core sandwich panel composites. Blingardi et al. [8] investigated the mechanical properties of the foam core sandwich panel composites using 4-point bending tests. It was found that skin–core delamination due to shear failure is the principle cause of structural failure of the sample. It was also established that the addition of a resin network perpendicular to the skins enhances flexural strength and impact resistance of the structure. Zhang et al. [7] investigated the effect of corrugation angle, core-sheet thickness, and core to skins bond length on the flexural strength of the corrugated core sandwich panel composites in the transverse direction of corrugation. It was found that not only failure occurs in the bond length but also specific flexural strength at a given corrugation angle and core-sheet thickness is reduced due to an increase in the bond length.

When 3-D fabrics are used as reinforcement in composites, the presence of Z-yarn along the thickness eliminates the poor bonding of the laminated layers [5, 12]. The integrated composites reinforced with 3-D fabrics have higher inter-laminar shear load-carrying capacity than the non-integrated version. The integrated composites possess higher delamination resistance. Additionally, strength along the thickness in the integrated structures is higher than those of the non-integrated version. The mechanical and thermal stability of the integrated structures along principle directions is unique [5, 13]. Karahan et al. [14] compared conventional foam core sandwich panel composites with 3-D integrated sandwich panel composites in which the connection of the skins to each other was made using pile yarns. It was concluded that the use of pile yarns significantly improves the compression behavior of the 3-D integrated sandwiched panel. Ivanov et al. [15] and Lomov et al. [16] compared conventional non-integrated 2-D woven laminated composite with integrated non-crimp 3-D orthogonal woven composite. It was found that as far as in-plane strength, failure strain, and damage initiation thresholds were concerned, the integrated composite was significantly superior in comparison with the non-integrated.

As you start digging deeper into the big world of e-commerce shipping, you’ll notice a few things:Get more news about Packaging Boxes 1 Layer,you can vist our website!

There are lots of different types of boxes out there. Who knew that there were hundreds of variations of corrugated cardboard boxes?
Some of the terminology used to describe boxes is dense and downright confusing. What does all of this mean?
First, rest assured that you don’t need to memorize any complex codes or charts. You just need to understand enough to find the cardboard boxes that suit your business.

In this post, we’ll do a brief overview of the different types of corrugated cardboard boxes so you are prepared to make the right choice.

What is fluting?
In cardboard boxes, fluting is formed by the arched shapes (flutes) that create space between layers of cardboard. Fluting helps make cardboard boxes durable and protect any contents inside.

Flutes are available in different sizes (measured by flute height, which dictates how thick a cardboard box’s walls are) and densities (measured by flute grammage, which shows how dense the paper in a box’s walls is ).
Single wall cardboard boxes have walls that contain one layer of fluting. In other words, each box is made up of three layers – an outer layer of paper + a single layer of flute + an outer layer of paper. These boxes are lightweight and suitable for products of average weight and fragility. DS Smith’s single wall boxes have a thickness of 3 mm and can ship and store packages with a maximum weight of 10 Kg (or 5 Kg if sent on pallets).

Single wall boxes can come in all kinds of shapes and sizes. Discover the large range in our online shop to find the one that fits your products perfectly:

Double wall cardboard boxes feature walls with two layers of fluting. Each double wall box is made up of five layers – an outer layer of paper + a layer of flute + a layer of paper + another layer of flute + an outer layer of paper. These boxes are stronger and more durable than single wall boxes, so they are more suited to heavier items or products that need additional protection and cushioning. DS Smith’s double wall boxes have a thickness of 5mm, and can support up a weight of up to 20 Kg (or 10 Kg if shipped on pallets).

Maximum weight recommendations for each box type may vary, depending on the type of product being shipped, the void fill or protective material included and the shipping method used.

Don’t take any chances with your products. Use DISCS ­– Drop, Impact, Shock, Crush, Shake – DS Smith’s industry leading distribution testing process, and get tailored packaging recommendations that fit your distribution model. DISCS will put your products through real-life shipping scenarios to determine what packaging will offer the best protection.

After being exposed to damage risks – being carried and loaded onto different modes of transport, possibly dropped and bumped along the way – you will be sure your package is sturdy enough to survive the journey to your customer.

Furniture leaders speak on pandemic impact

During a 15-month period with an unusual level of disruption, the West Michigan commercial furniture and design industry rebounded faster than expected, but according to three local CEOs, challenges remain.To get more news about Home furniture manufacturer, you can visit beour.com official website.

The Economic Club of Grand Rapids on May 17 hosted a panel discussion, “Shaping the Workplace,” featuring Andi Owen, Franco Bianchi and Jim Keane, presidents and CEOs of Herman Miller, Haworth and Steelcase, respectively.

The trio shared insights on workplace trends prior, during and post-pandemic; sales channels; and corporate responsibility, including environmental and social health and wellness.

Deirdre Jimenez, president and CEO of Grand Rapids-based Business and Institutional Furniture Manufacturers Association (BIFMA), moderated the discussion.

Jimenez noted in her opening remarks that “the pandemic paused projects, stalled commercial real estate transactions and slowed new product orders,” leading to softening revenue in the U.S. commercial furniture industry. However, while the financial impact of the pandemic for 2020 was originally forecast to be a 20% decline, the year finished with a 13% decline.

“IHS (Markit) forecast that the furniture industry will slowly continue to rebound in 2021 and 2022, and signs are already pointing in the right direction,” she said. “According to a recent Bloomberg report, office searches that had been postponed are reactivating, fueled by a pursuit for less expensive rates and more concessions from landlords who are eager to bring people back to their buildings. According to property data from (Design Trade Service), which tracks office tours, national demand for office space jumped 28% in March from the prior month and is now just 9% below pre-pandemic levels.”

Additionally, February architectural billing index data showed upticks in design contracts and billing for the first time since the pandemic, Jimenez said.

“These signals would indicate that companies are planning a return to the office, and with the CDC lifting guidelines, that shift will be happening sooner rather than later,” she said. “The amount of office space companies need may change, but with change often comes remodels, and with remodels often comes new furniture.”

For years before the pandemic, Jimenez said strategies gaining momentum included the open office and remote work, which evolved from being mobile within one’s office through the creation of “neighborhoods” to being able to shift from working from home to working in the office through the use of “hoteling” stations in the workplace and performance seating at home.

When the pandemic hit, shelter-in-place restrictions forced the accelerated adoption of remote work, and people quickly discovered their non-ergonomic home furniture — sitting at the kitchen table or working in bed all day — wasn’t cutting it.

Owen said Herman Miller adapted to the increased demand for home office solutions by continuing its residential office catalog, upgrading its e-commerce delivery platforms, tailoring its logistics to deliver to individuals as well as businesses, and adding five U.S. retail stores and one in Tokyo. She said it might sound counterintuitive to expand brick-and-mortar during a pandemic but sinking real estate prices made it a risk worth taking.

“Our strategy at Herman Miller is really the idea of meeting our customers wherever and everywhere that they are,” she said. “… Our customers are very intentional, and they want and need advice from product specialists, especially in the home office category.”

Best juicer 2022: ranking the best we've tested

The best juicer can ensure you always have access to fresh orange juice at breakfast time or can enjoy a refreshing fruity beverage anytime, without having to swing past the grocery store or juice bar. Suitable for a range of fruits including citrus, berries, and tropical varieties, as well as robust vegetables and even leafy greens like Kale, the best juicer can offer an easy way to boost your nutrient intake. To get more news about Lemon peeling and seedless juicer, you can visit hl-juicer.com official website.

When it comes to choosing the best juicer for you, there are two styles to pick from. A centrifugal juicer is the most affordable of the two. It uses rotating blades to juice the fruit and is quicker than a cold press juicer, which grinds and chews up the fruit and vegetables, pushing the mixture through a strainer to separate the juice from the pulp.

A cold press juicer, which is also known as a slow juicer or a masticating juicer, preserves more nutrients and extracts larger quantities of juice from fruit and vegetables than a centrifugal juicer. Our article offers an in-depth look at what is a cold press juicer, while for tips on juicing, read how to use a juicer.

If you’re looking to increase the quantity of fruit and vegetables you consume, one of the best juicers can prove extremely helpful. However, if you’re concerned about the health implications of juicing, read our article on how healthy is using a juicer.

Of course, juicers aren’t the only way to enjoy a refreshing fruit beverage. If you’re partial to a smoothie rather than a juice, you’d be better off with one of the best blenders instead. They blitz fresh produce into a silky smooth drink, rather than extracting the juice.

With such a wide array of juicers to choose from, you may be left feeling overwhelmed about which is best for you. There are a range of dedicated juicer brands such as Kuvings and Nama, but these tend to be expensive. Whereas well-known appliance brands including Nutribullet, Smeg, and Breville, which also produce coffee makers and espresso machines too, offer a range of more affordable models.
If you’re looking for the best juicer you can buy, Breville's the Juice Fountain Cold hit the sweet spot when it comes to juice yields, simplicity and price. With a 70oz/ 2L lidded jug and 3.6 qt/ 3.4L pulp container, this juicer can make large quantities of juice in one go, and we were impressed at just how clear the juice produced was, and the fact there was no pulp included in the juice either.

Known as the Sage the Nutri Juicer Cold in the UK, this is a centrifugal juicer but it features ‘Cold Spin Technology’ which the brand claims will ensure the juicer stays cool, despite its high spin speed to avoid any heat damage to vitamins and minerals during the juicing process.

If you’re a fan of kale shots, then this isn’t the juicer for you, as it struggled to extract much juice from leafy greens, and we also found that while juices were smooth, they had a thick layer of foam. However, considering its mid-range price tag, we think is definitely a juicer worth considering.
With a price tag of under $100 / £100, this slow juicer represents excellent value for money and ideal for those on a budget but still want high juice yields or to make refreshing drinks from leafy greens.

On test we found it easy to assemble and simple to use. The juice yields were slightly below what we’ve seen from more premium slow juicers but exceeded the results from its nearest competitor in terms of price, the Ninja Cold Press Juicer. The components are dishwasher safe, which makes for easy cleaning, too

However, the feed chute is smaller than other juicers we’ve tested, which means you will have to spend time chopping up fruit and vegetables before juicing them and the instruction manual wasn’t as detailed as we’d have hoped.

Juicer Types: The Difference Between Cold Press Juicers vs. Centrifugal Juice Extractors

It's entirely possible that you're curious about buying a juicer. In case you haven't heard, juicing is trending. We're not talking about the Barry Bonds type of juicing, but the Jack LaLanne type. Recent claims have promised that drinking fresh-pressed juices can help you lose weight, boost immunity, prevent cancer and cleanse your system. Whether that's entirely true remains to be seen, but it can't hurt, right?To get more news about High Quality Industrial Juice Extractor, you can visit hl-juicer.com official website.

We're food editors, so we obviously don't hate food enough to go on a full-on juice cleanse. But it would be nice to incorporate those health benefits into our diet -- you know, to clean out all the totchos and doughnuts in there. The only problem is deciding which juicer to buy.
Unless you're a millionaire who can afford the original Norwalk hydraulic press juicer for $2,495, there are two basic types of options on the market for you:

1. Centrifugal Juice Extractors
Traditionally, this is the most common type of juicer. These typically utilize a fast-spinning metal blade that spins against a mesh filter, separating juice from flesh via centrifugal force. The juice and pulp are then separated into different containers. The problem with centrifugal juicers is that the fast-spinning metal blade generates heat, which destroys some of the enzymes in the fruits and vegetables you're juicing. The heat also oxidizes those nutrients, rendering less nutritious juice than a cold-press juicer.
2. Cold Press Juicers (a.k.a. Masticating Juicers)
These newer juicers extract juice by first crushing and then pressing fruit and vegetables for the highest juice yield. Because they don't produce as much heat, they keep more of the fresh ingredients' nutrients intact. This is closer to what you'll get (but NOT the same) from a BluePrint type of cleanse.

Squeezing an orange for juice is part of the concept of this machine, only on a much larger scale. The extractor revolutionized the juice industry. The twenty-four head rotary action simultaneously extracts juice from the interior of the fruit and citrus oil from the peel surface. The first unit was operated experimentally on grapefruit at the Sunkist Exchange plant in Tempe, Arizona, during late May of 1946. Tests on citrus fruits continued in California, Texas, and Florida. By 1950 the process was improved by including a system for producing high-quality prefinished juice directly from the extractor. FMC extractors are located worldwide in all major citrus areas.
