应用简支梁冲击仪测试了中空玻璃微珠(HGB)填充聚丙烯(PP)复合材料V型、U型缺口及无缺口试样的冲击性能,采用灰色关联分析原理计算了HGB的粒度分布与填充PP复合材料冲击断裂能的灰色关联度,以考察HGB粒度分布对填充PP复合材料冲击断裂能的影响.结果表明,在考察的粒度分布范围内,粒度小于24.72μm的颗粒对复合材料冲击断裂能均有增强作用,其中以粒度在18.90～24.72μm之间的颗粒的增强作用最大,而粒度大于24.72μm的颗粒对复合材料的冲击断裂能均有削弱作用,以粒度在100.6～256.0μm之间的颗粒的削弱作用最强.因此,为提高复合材料冲击断裂能,需提高粒度小于24.72μm的颗粒的体积百分含量,尤其是粒度在18.90～24.72μm之间的颗粒的体积含量.
