Abstract

A 2D random void model (RVM) is proposed to describe voids morphology in Carbon Fiber Reinforced Plastic (CFRP) composite materials and used to investigate Ultrasonic Scattering Attenuation Coefficient (USAC). Void morphology simulations from RVM present good matches to micrographic observations. The fluctuations of USAC due to the randomness of void morphology and their dependence on the frequency have been discussed, which are significantly helpful to clarify ultrasonic scattering attenuation mechanism from voids in nature.
