Simply put, composites are a combination of components. In our industry, composites are materials made by combining two or more natural or artificial elements (with different physical or chemical properties) that are stronger as a team than as individual players. The component materials don’t completely blend or lose their individual identities; they combine and contribute their most useful traits to improve the outcome or final product. Composites are typically designed with a particular use in mind, such as added strength, efficiency or durability.
What are composites
Composites, also known as Fiber-Reinforced Polymer (FRP) composites, are made from a polymer matrix that is reinforced with an engineered, man-made or natural fiber (like glass, carbon or aramid) or other reinforcing material. The matrix protects the fibers from environmental and external damage and transfers the load between the fibers. The fibers, in turn, provide strength and stiffness to reinforce the matrix—and help it resist cracks and fractures.
Provides strength and stiffness (glass, carbon, aramid, basalt, natural fibers)
Protects and transfers load between fibers (polyester, epoxy, vinyl ester, others)
FIBER COMPOSITE MATRIX
Creates a material with attributes superior to either component alone
In many of our industry’s products, polyester resin is the matrix and glass fiber is the reinforcement. But many combinations of resins and reinforcements are used in composites—and each material contributes to the unique properties of the finished product: Fiber, powerful but brittle, provides strength and stiffness, while more flexible resin provides shape and protects the fiber. FRP composites may also contain fillers, additives, core materials or surface finishes designed to improve the manufacturing process, appearance and performance of the final product.
Natural and synthetic
Composites can be natural or synthetic. Wood, a natural composite, is a combination of cellulose or wood fibers and a substance called lignin. The fibers give wood its strength; lignin is the matrix or natural glue that binds and stabilizes them. Other composites are synthetic (man-made).
Plywood is a man-made composite that combines natural and synthetic materials. Thin layers of wood veneer are bonded together with adhesive to form flat sheets of laminated wood that are stronger than natural wood.
Not all plastics are composites. In fact, most plastics—the ones used in toys, water bottles and other familiar items—are not composites. They’re pure plastics. But many types of plastic can be reinforced to make them stronger. This combination of plastic and reinforcement can produce some of the strongest, most versatile materials (for their weight) ever developed by technology.
Polymer resins (such as polyester, vinyl ester, epoxy or phenolic) are sometimes referred to as plastic.
By any other name…
Why composites ?
Patent pending aramid fiber/carbon fiber insoles fit a wide range of footwear, even ones with non-removable factory insoles. The aramid fiber/carbon fiber breakthrough design combines the strength of carbon fiber with the force absorption of kevlar to create the most innovative insole ever.
Barruning revolutionary insole achieves a new level of lightweight performance by combining an aramid fiber with carbon fiber providing alignment guidance and support for feet. The insole targets the arch of the foot, allowing the arches to work on demand. Biomechanical shape: the low-profile contour shape helps align the foot and the arch to articulate which can help reduce stress on the feet, knees and hips; while also reducing the stress on the muscles of the legs. The contour shape helps accommodate a wider range of footwear.
How it works: arch-ticulation insoles help adapt the curve arch of the foot to footwear. The foot behaves in a natural manner while wearing shoes and socks. The arch-ticulation (archticulation) insoles provides a consistent stable feedback signal to the brain allowing for traction to be applied at the given time of impulse.
Best insole by far. 1. Dual purpose with a speed side and a power side. 2. No arch support but activates the 3 arches of the foot to give you 100 percent load bearing capabilities. 3. Levels the 3 end points of the arches to give you superior stability. 4. Does not interfere with the foot operating as a class 2 lever. And so many other benefits that regular insoles do not and can not provide.
Aramid fiber helps with force output and absorption. The carbon fiber helps with force return.
