MOST PREPREGS TEMPORARILY OUT OF STOCK: Due to global supply chain issues we have temporarily disabled the sale of most prepregs. We anticipate a resupply of most styles by late summer 2021. Please check back often while as we plan to update this category immediately upon receipt of more materials.
Have you ever wondered how aircraft interiors and Formula 1 cars are so stiff and light? The secret is sandwich panels. Sandwich panels are used whenever lightness and stiffness are required for a flat or irregular shape. The main theory behind sandwich panels is the concept of mass moment of inertia. Increasing the mass moment of inertia directly increases the stiffness. So how do you increase the mass moment of inertia while keeping weight down?
First, let's consider a solid carbon fiber plate. Thicker plates will be stiffer, but not just because there is more material. When layers are further from the center (commonly called the neutral axis) they contribute more stiffness. Consider two tubes of different diameter. The large diameter tube will be stiffer than the small diameter tube, even if the amount of materials in them is equal! This is because the larger diameter tube has more material further from the center.
An I-beam works using the same principal. The web of the I-beam (the skinny center section) holds the flanges (the end pieces) far from the center, making the beam much stiffer than a solid plate using the amount of material. (See Figure 1.)
So, we know a thick plate will be stiffer but we need something lightweight. That's when the sandwich comes in. When a plate bends, the outermost layers don't just add the most stiffness, they also take a majority of the load. Both faces will experience stress with one in compression and one in tension. Strangely enough, the center of a bending plate sees no stress at all! Therefore, if we know the center layers of a plate don't contribute much we can eliminate them and replace them with foam or honeycomb.
Replacing the center layers reduces overall stiffness a little bit, bringing us right back to the mass moment of inertia by effectively moving the load carrying materials (also referred t as the panel "skins") further from the neutral axis. If we make the core thicker we've increased the mass moment of inertia and increased the bending stiffness and strength. If we add more layers we can also increase the strength and stiffness since we add more materials far from the center, and we can distribute the load over more cross-section. Getting the thickness right results in a panel that is considerably lighter than an equivalent solid panel. Rock West Composites offers sandwich panels in a multitude of thicknesses and constructions to suit your needs. And as always, if we don't have it shoot us an email or give us a call and we CAN build it for you!

Rock West Composites Introduces New Marine Division Before DEMA Show 2021
Rock West Composites announces the launch of its new Marine Division a week in advance of its attendance at DEMA Show 2021 in booth #1424. Initially focusing on supplying original equipment manufacturers with composite components, Rock West will display new custom products, in addition to off-the-shelf products and materials, relevant to the marine market.
San Diego, CA (PRWEB) November 9, 2021 – Rock West Composites (RWC) announces the launch of its new Marine Division in advance of its attendance at DEMA Show 2021, a premier trade-only event for businesses in the ocean diving and watersports markets. RWC will be in booth #1424. Targeting original equipment manufacturers (OEMs), RWC believes that its unique experience with high-performance industries and commercial markets will enable it to provide high quality products that are both cost effective and schedule sensitive, key issues that are challenging to OEMs.
RWC will be focusing on applications including carbon, glass, and hybrid composite free dive fin blades, wrapped and filament wound pole spear tubing, speargun chassis, gaffs, harpoons, technical diving backplates, and mechanical component substructures.
At DEMA Show 2021, the company will highlight a new product, a composites fin blade, which will be on display in the New Product Showcase. The materials are 100% carbon fiber, woven, uni-directional prepreg epoxy. The laminate is quasi-isotropic, strategically stepped and balanced. It has a medium- and soft-flex version available. Blade dimensions are 752mm X 210mm, and it weighs 235 grams. The attachment tendon is a 22-degree angle designed to fit most popular foot pockets. RWC fin blades are designed for high-performance continuous use conditions and are made using the highest quality carbon fiber, fiberglass, and epoxy resin systems and processes.
“We are excited about what we can contribute
We are excited to announce that Rock West Composites (RWC) has been awarded a Top Workplaces 2021 honor by Salt Lake Tribune Top Workplaces. The list is based solely on employee feedback gathered through a third-party survey and administered by employee engagement technology partner Energage LLC. The anonymous survey uniquely measures 15 culture drivers that are critical to the success of any organization: including alignment, execution, and connection, just to name a few.
While this honor is specific to our Salt Lake City facility, RWC’s team strives to provide a great place for people to work, learn and grow. At the top of our list of brand values is that “our workplace should be fun, creative and empowering for employees.” In addition to management’s open-door policies, our team takes quarterly employee satisfaction surveys to help management guide changes to improve the work culture. Everyone at every level of the business is eligible for the annual All Team Bonus Award. Training and career growth is a key metric in employee reviews. And the company has one of the best benefits packages around.
Even surveys on benefits help to guide improvements for the packages offered to staff. “While Rock West offers an outstanding benefits package for a business of this size, we’ve made changes to our benefits based on employee feedback. We increased company contributions to insurance coverage for dependents and increased paid time off for newer employees. I love being able to address employee concerns directly by getting real data and taking action accordingly,” says Grace Hernandez, Director of Human Resources.

Are you interested in doing a project with composites but not sure exactly where to start? Perhaps you know what you want to do but just want a kit to get you going? We've got the solution!
Get started on your own project with our new Wet Layup Starter Kits. We have two sizes available depending on the size of your project and your level of experience. We recommend everyone have a well-ventilated workspace, a work surface that is protected from damage or will not be harmed by potential epoxy resin spills, and as always safety glasses (not included).
The small wet layup kit includes carbon fiber fabric, fiberglass cloth, resin and harder (packets), hi-temp release wax, gloves, cups, stir-sticks, brushes, and a naca duck mold for your first project, but you can use another mold if you have one. The amount of fabric and resin is enough for a small part or two).
If you have a more ambitious project in mind, the large wet layup kit includes greater quantities of carbon fiber fabric, fiberglass cloth, resin and harder (full containers), hi-temp release wax, gloves, cups, stir-sticks, brushes, and a wedge to help you remove your part from a larger mold. The amount of fabric and resin is enough for a a few larger parts.
We made some videos to help you get a visual of what is included with the orders and also give you project ideas. So take a look and order your wet layup starter kits today!
