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. Tensile testing also shows that in modified PC the critical fiber length is quite shorter than the one in standard GFPC. Although the interface strength is improved, the fatigue lifetime of PC-PDMS is found to decrease because many crack tend to initiate and propagate around the fiber ends.}, pages = {SMM0185-1--SMM0185-10}, title = {変性PCを用いたGFRPの疲労特性と損傷機構の考察}, volume = {80}, year = {2014}, yomi = {クロシマ, ヨシヒト and ノダ, ナオアキ} }
