Composite Material
is a combination of two or more distinct materials, having recognizable interface between them. Composite are used not only for their structural properties but for electrical, thermal and environment applications.
Fiber Reinforce Plastic (FRP)
Fiber Reinforce Plastic are made of two primary constituents; Fiber and a polymer matrix. In FRP, the fiber is embedded in polymer matrix. This structure gives completely different chemical and physical properties than the properties of the individual materials. The primary role of fibers is to provide strength and stiffness to the material. But the fiber alone is brittle. Therefore, the fiber are encased in coating of polymer materials. Polymer matrix holds the fibers in their position and transfers the loads between the fibers. It also contributes to the inter-laminar shear strength.
