Abstract:Single carbon fiber (CF)-embedded thermoset epoxy resin (EP) and thermoplastic polycarbonate (PC) specimens were prepared to clarify the interfacial interaction between CF and a matrix polymer and the deformation behavior of the carbon fiber and a matrix polymer. Stress−strain curves of EP and PC samples including and excluding CFs showed yields at approximately 70 MPa. In situ polarized high-speed camera images of the samples revealed the effect of CF on stress propagation. Moreover, the retardation of the fi… Show more
