Effect of temperature on the fiber/matrix interfacial strength of carbon fiber reinforced polyamide model composites

Carbon Fiber Reinforced Thermoplastics (CFRTP) have attracted attention in the automotive industry for their productivity and high specific strength and modulus. To guarantee the durability of CFRTP, it is important to understand the mechanical properties of CFRTP under practical service temperature...
