What are fiber reinforced composites and how are they made?
Fiber reinforced composites are materials that consist of a combination of fibers and a matrix material. The fibers provide the primary load-carrying capability, while the matrix material binds the fibers together and protects them from environmental damage. The manufacturing process for fiber reinforced composites typically involves several steps, including the selection of the fiber and matrix materials, the preparation of the fibers, and the combination of the fibers and matrix to form the composite material. This process can be accomplished through a variety of methods, including hand layup, vacuum bagging, and resin transfer molding.
The choice of fiber and matrix materials depends on the desired properties of the final composite material. For example, carbon fibers are often used in high-performance applications due to their high strength-to-weight ratio, while glass fibers may be used in more cost-sensitive applications. The matrix material can be a thermoset or thermoplastic polymer, with thermoset polymers being more common due to their high strength and stiffness. The properties of the fiber reinforced composite can be tailored by adjusting the type and amount of fiber, the type of matrix material, and the manufacturing process used to combine the fibers and matrix. This allows fiber reinforced composites to be used in a wide range of applications, from aerospace and automotive to construction and consumer products.
