EFFECT OF MOLDING METHOD AND TECHNOLOGICAL PARAMETERS ONMECHANICAL PROPERTIES OF GF/PP COMMINGLED YARN

Abstract

Abstract: The glass fiber/polypropylene (GF/PP) commingled yarn was laminated by compression molding under various process parameters. The effects of molding temperature, molding pressure and dwell time on the mechanical properties of GF/PP composites were investigated by orthogonal test. Tensile strength, flexural strength and impact strength were used to evaluate the mechanical properties of GF/PP composite laminates. The results show that comprehensive mechanical properties could be improved by preloading before molding compared to the direct molding compression. The optimum process parameters of laminates made of GF/PP continuous composite fiber fabric was found, for which the molding temperature was 210 ℃, the pressure applied on the laminate was 10 MPa, and the holding time was set as 20 min.

Key words: GF/PP commingled yarn, laminate, orthogonal test, mechanical properties, composites
