Environmental Effects on Damage Tolerance Performance of CFRP Laminate for Marine Uses

抄録

In multiaxial stitched CFRP laminates, it is thought that the existences of knitting fibers in between layers and gaps between carbon fiber bundles etc., which are configurations different from conventional unidirectional and woven laminates, significantly affect the interlayer fracture properties. Besides, objective large-scale structures are affected by environment such as variable temperature and humid, thus the interlayer fracture properties might become more complicated. In this study, Mode I and Mode II interlaminar fracture toughness and the crack growth property under fatigue, thermal and water environments of multiaxial stitched CFRP laminates for innovative marine composites were investigated.
