Mechanical behavior of fiber/matrix interfaces in CFRP sheets subjected to plastic deformation

Mechanical behavior of fiber/matrix interfaces in CFRP sheets subjected to plastic deformation

The use of Carbon Fiber Reinforced Plastic (CFRP) is increasing markedly, partially in the aviation industry, but it has been considered that CFRP sheets cannot be formed by press-forming techniques owing to the low ductility of CFRP. Since the mechanical characteristics of CFRP are dominated by the...
