| contents | Mode I interlaminar fracture toughness tests were performed with glass satin woven fabric phenolic resin composite materials. The composite panels were fabricated with the phenolic resin containing different amount of polyetherketone (PEK) to investigate the influence of PEK content on the fracture toughness. The results show: the fracture toughness has remarkably improved by increasing the content of PEK while the tensile properties have not considerably changed. For the panel whose matrix contained 40% PEK, its GIC value measured here is 1.209 KJ / m2, which is more than 4 times of that of the panel without PEK. The scanning electron microscope (SEM) observation of fracture surfaces indicated that increasing the content of PEK to 40% not only evidently improved the fiber / matrix interfacial quality, but also toughened the matrix and changed the failure mechanism of the matrix from the brittle into the ductile. |
