変性PCを用いたGFRPの疲労特性と損傷機構の考察
In this study, for the matrix / fiber interface strength is investigated in the fatigue experiment for the glass-fiber reinforcing polycarbonate (GFPC). Here the effect of modified PC resin is discussed when Epoxy (EP) or Polydimethylsiloxane (PDMS) are blended into PC. The microscopic damage process and fracture surface is examined through the optical microscope and the scanning electron microscope. The EP and PDMS are found to improve the matrix / fiber interface strength since they may control crack propagation along the fiber.
