概要

The effect of moisture absorption on the static and fatigue properties for plain woven CF/epoxy composite were examined with changing humidity at each stage; mixing, lamination, storage and testing stage. The experimental results showed that the static strength and fatigue life of plain woven CFRP were significantly improved when the material was protected from moisture absorption during the mixing and lamination stage. This prevention improved the resistance of crack growth in DCDC test and interfacial shearing strength at the interface between fiber and matrix in micro droplet test. Such improvement of fiber/matrix inter facial properties contributed to the enhancement of the static strength and fatigue life of plain woven CFRP.
