摘要

In this paper, the effects of fiber surface treatment on the mechanical and thermal properties of glass woven fabric reinforced thermosetting epoxy resin matrix composites are examined experimentally. Four kinds of deposit (pick-up) ratios of polyurethane dispersion (PUD) treatments on the heat-cleaning glass cloth woven fabric were carried out, including Owt% (without treatment), 0.76wt%, 1.51wt% and 6.49wt%. It is found that the interfacial adhesion and property were affected by the treatment significantly. The correlation among varied PUD surface treatment pick-up ratio of glass fiber, modified interface, improved mechanical property and related thermal property were discussed and clarified based on tensile test, dynamic mechanical analysis (DMA), scanning electronic microscope (SEM) observation.
