【摘要】 本文以苎麻纤维和玻璃纤维为增强材料,以聚丙烯纤维为树脂基体,经非织造工艺制备预成型件后,采用模压成型工艺制备了不同增强纤维体积分数的复合材料。分别对复合材料纵、横向的弯曲强度和剪切强度进行了测试,结果表明,当苎麻/PP复合材料中苎麻纤维的体积分数为40%、苎麻/玻纤/PP复合材料中玻璃纤维的含量为5%时,复合材料具有最好的力学性能。材料的弯曲断裂面微观形貌分析表明,聚丙烯体积分数越多,复合材料中树脂对纤维的浸润性越好。更多还原

【Abstract】 Different fibers volume fraction of Ramie fibers and Ramie fibers/Glass fibers reinforced polypropylene composites were prepared by means of ramie fibers,glass fibers and polypropylene fibers,nonwoven process and mould-pressing technology.Then tested the flexural properties and shear properties of the composites.The results showed that;mechanical properties of ramie/PP and Ramie /Glass fibers/PP composites attain a peak while the volume fraction of ramie fiber is 40%,The volume fraction of glass liber is 5%.The fracture surface reveals that a higher volume fraction of polypropylene enabled successful fiber-matrix adhesion.更多还原
