Abstract
Flexible rubber coatings were obtained with which to coat glass fibre surfaces for use in a polypropylene matrix. The polymeric coatings were obtained by using two rubbers, cis-polybutadiene rubber and EPDM, and two block copolymers, polystyrene-block-polybutadiene-block polyvinyltriethoxysilane and polystyrene-block-polyvinyltriethoxysilane. The effect of the coatings on the interfacial adhesion and thermal cycling resistance of composites were studied by a single-filament fragmentation technique which was designed to measure the interfacial shear strength of the composite. It was found that the interfacial shear strength was improved by the rubber coatings, which could graft to silane coupling agents coated onto the fibre surfaces and could undergo crosslinking under peroxide initiation. The interfacial bond strength was determined by the nature and thickness of the rubber coatings. Interfacial adhesion was also seen to improve when using block copolymers to treat glass fibres. The rubbers and those copolymers having flexible blocks in their structures both produced coatings that could relieve the thermal stresses at the composite interface during temperature cycling. The interface between the composites and the flexible polymer coatings had good thermal cycling fatigue resistance. 18 refs.
