Carbon fiber reinforced thermoplastic (CFRTP) has high specific strength, rigidity and corrosion proof. CFRTP is used for structural members such as aircrafts, automobiles, blades of electricgenerating windmills and sporting goods. Because the mechanical strength of CFRTP depends on the volume fraction, the evaluation of the volume fraction of CFRTP is very important in the guarantee of quality. Thus, the nondestructive inspection method to detect the volume fraction in CFRTP is required. In this paper, we measured the conductivity of CFRTP from the reflection wave of the microwave. Using a theory model, the volume fraction was evaluated from the conductivity. As a result, the potential of microwave inspection to evaluate the volume fraction in CFRTP was presented.
