螺杆转速对PP/GF复合材料中GF与性能的影响
Effects of Screw Rotation on Glass Fiber in Matrix and Properties of PP/GF Composites
摘要
Abstract
Polypropylene (PP)/glass fiber(GF)composites were prepared by a co rotating twinscrew extruder,and the effect of screw rotation on GF in the composites and the properties of composites was investigated.The results indicated that the content of GF increased with an increase of rotation speed and achieved a maximum value of 48.2 ％.However,the fiber length tended to decrease gradually with increasing rotation speed.The tensile strength,bending strength,heat-resistant temperature and hardness of the composites were improved with the increase of rotation speed,but the impact strength showed a slow decline.The incorporation of maleic anhydride-grafted PP improved the fiber length significantly,and meanwhile,the GF content,tensile strength,bending strength,notched and no-notched impact strength increased 1.8 ％,95.1 ％,90.1％,50 ％ and 110.4 ％,respectively.关键词
