Mechanical Properties and Dynamic Mechanical Behavior for Long Aramid Fiber Reinforced Impact Polypropylene Copolymer

摘要：

　　Composites of continuous aramid fiber reinforced impact polypropylene copolymer (IPC) were prepared using a cross-head impregnation mold by self-design fixed on a single screw extruder,and pelleted by a pelleter for injection molding to prepare testing specimens.The mechanical properties of long aramid fibers reinforced impact polypropylene copolymer (IPC)composites were studied.Micrographs of fracture surface of tensile specimens and dynamic mechanical behavior for the composites were analyzed by scanning electron microscope (SEM) and dynamic mechanical analyzer (DMA).The results of experiments show that,the tensile and flexural strengths increased obviously with the aramid fibers content in the composites.SEM results show the compatibility between the aramid fiber and matrix is very poor.The results of the dynamic mechanical behavior of long aramid fibers reinforced IPC composites show that the composite deformation resistance and glass transition temperature increased evidently with the addition of aramid fibers.
