Fiber reinforced composite material is composed of reinforcing fiber and matrix.The diameter of the fiber (or whisker) is very small, generally below 10 m, with fewer defects and smaller, and the fracture strain is less than 30 thousandths, which is brittle material, liable to damage, fracture and corrosion.The matrix is much lower in strength and modulus than the fiber, but it can withstand large strain. It is usually viscoelastic and elastoplastic and is a ductile material.
According to the length of fiber, FRP can be divided into short fiber reinforced composite plastics and long fiber (or continuous fiber) reinforced composite plastics.
Fiber properties can be divided into high performance fiber composites and engineering composites.
