OS0514 Relation between fatigue strength property and damage mechanism in GFPC having modified resin/fiber interface

Abstract

The study considered the relation between fatigue strength property and damage mechanism in GFPC having modified resin/fiber interface by observing the fracture, and the fatigue testing. 1) Damage was initiated at the fiber end in the early stages of the fatigue process, and debonding propagated along the fiber interface. 2) In fatigue testing, the number of cycle difference in a high stress is based on the difference in a damage mechanism.
