摘要: Plain woven AFRP samples were immsersed in hot water at 80°C and exposed to humid air 80°C, 80% RH for 300~days. Furthermore, they tested by a tensile method investigate time dependence of their degradation. The longer the immersion time, greater degradation strength. But on comparison with air, those immersed showed more degradation, although both conditions had same temperature. Hot caused yarn/resin interface degrade led delamination. Warps, which are weakened absorption, further damaged Damaged warps broke final fracture occurred low level stress.
