Technical Field

Background
Fiber-reinforced composites can be divided into continuous fiber-reinforced composites and chopped fiber-reinforced composites. Chopped fibers are much less strong than continuous fibers. The mechanical properties (bending strength, fracture toughness, etc.) of the fiber-reinforced composite material are closely related to the fiber content and the distribution state thereof in the matrix.
