This paper presents electrical and mechanical properties of compound consisting of thermoplastic resin mixed with carbon fiber reinforced plastic (CFRP) pieces. CFRP pieces made by crushing CFRP wastes are utilized in this material. Nine kinds of compounds with different weight fraction and size of CFRP pieces are prepared. Firstly, electrical impedance of the compounds was measured as a function of frequency. Electromagnetic shield effect of the compounds was also investigated and compared with that of a CFRP laminate. Secondly, mechanical properties such as tensile and flexural strength were measured. Finally, the polished surface and fracture surfaces of the specimens were microscopically observed to investigate the effect of orientation and distribution of CF and CFRP pieces on mechanical and electrical properties. The compound has a variety of conductivity depending on content of CFRP pieces. Mechanical properties also increase with increasing CFRP content.
