EFFECT OF FIBER-MATRIX INTERACTION ON FATIGUE FRACTURE MORPHOLOGY OF GLASS-FIBER REINFORCED POLY (BUTYLENE TEREPHTHALATE)

抄録

Fatigue tests of glass fiber reinforced poly (butylene terephthalate) (PBT) composites were carried out at 303K. The composites of surface-modified glass fiber showed greater fatigue strength compared with that of surface-unmodified glass fiber. Scanning electron microscopic observation of the interface between glass fiber and polymer matrix revealed a remarkable influence of interfacial adhesion on fatigue strength of the composites.
