摘要：

The aim of this study is to demonstrate the relations between surface, interphase and different composite properties in composites of carbon and glass fibres and thermosets (epoxy resin) or thermoplastics (polyamide, polypropylene). The surface characteristics of variously treated carbon and glass fibres have been determined by contact angle measurements, using a capillary penetration technique, and zeta potential measurements. Micromechanical tests (single-fibre pull-out) have been applied to model composites to establish the interphase properties. Bulk composites have been manufactured by impregnation with resins and curing by hot pressing or pressing of commingled yarn samples (continuous reinforcing fibres) or twin-screw extrusion and injection moulding (short reinforcing fibres). The composite properties have been tested by tensile and shear tests. Contact angle and electrokinetic measurements permit detection of differences in the surface treatment of glass and carbon fibres. Measurements of shear strength by pull-out, fibre fragmentation and yarn tensile shear tests show comparable results and correlate to the macromechanical properties.
