Abstract
The following conclusions were obtained as a result of examining the fatigue strength characteristic and the relation of a damage process paying attention to damage to the resin/fiber interface in GFRP based modified PC. 1) Fatigue crack growth rate of the difference in the fatigue characteristics of PDMS-PC and PC-EP is the cause. 2) The damage process of PDMS-PC is a type of crack distribution destroyed while two or more GF end cracks connect.
