| 摘 要： | 纤维的流动分布对环氧片状模塑料(ESMC)制品的各项性能有十分重要的影响。以纤维含量作为性能指标,对原材料组分、片材黏度、铺层方式、模压工艺参数等因素与纤维流动分布的关系进行系统研究。研究结果表明,当玻璃纤维含量为24%、长度为24 mm、填料粒径为45μm、片材黏度为5×103Pa·s、铺料面积为60%、压机闭模速度为1 mm/s时,ESMC模压制品纤维分布的均匀性较好。

| Abstract: | The fiber flowing and distribution of epoxy sheet molding compound (ESMC) have great effect on the properties of ESMC parts.In this article,the relationships between raw materials,viscosity of ESMC sheets,molding parameters etc.and fiber distribution were systematically studied by measuring the fiber content of ESMC parts.The results showed that when the fiber content of ESMC was 24％,the length of fibers was 24 mm,the size of filler was 45 μm,the viscosity of ESMC sheets was 5 × 103 Pa· s,the layering area was 60％ and the velocity of mould closing was 1 mm/s,indicating a better fiber distribution of ESMC parts. |
