Fatigue Behavior of Tri-Axially Woven Fabric Composites

摘要：

　　Fatigue behavior of triaxially-woven fabric (TWF) composite and its damage propagation and accumulation mechanisms are experimentally investigated.Two types of TWF composites with different filament thickness are employed.S-N curves for these composites are constructed and the strain increment or ratcheting behavior under cyclic loading is investigated.The results reveal that the difference in filament number of fiber tows used affects the damage accumulation rates and the resulting final failures.The one with thicker tows behaves as more‘ductile’material.Debonding between adjacent tows,that is suspected to be the major initial damage,is also observed using X-ray CT scanning.
