双马来酰亚胺(BMI)-玻璃布复合材料成型工艺及性能研究

研究了作为改性ＢＭＩ一种的ＨＦ－９４０９树脂体系与玻璃布复合材料的成型固化工艺。在此工艺条件下，分别用ＡＢＳ树脂和氯磺化聚乙烯（ＣＭＳ）橡胶对ＨＦ－９４０９树脂体系进行改性。实验结果表明，加入１０％（质量比）ＡＢＳ树脂后，ＨＦ－９４０９树脂体系与玻璃布复合材料的拉伸强度和冲击强度分别提高了２２．３７％和１５．４６％，加入３０％（质量比）ＣＭＳ橡胶后复合材料的韧性提高了８．５１％，并从理论上分析了产生这种实验结果的原因。

On Molding Process and Properties of BMI/Glass Cloth Composite

Molding process of a composite of HF-9409 resin system compounds with glass clohts has been studied. The HF-9409 resin system was obtained from the modification of BMI. Under the condition of this processing, the HF-9409 resin system is modified by ABS resin and CMS rubber respectively.The experimentat results show that the tensile strongth of HF-9409 glass cloth can increase 22.37% and its impact strength can increase 15.46% if 10% more ABS resin are added to the composite, and that the toughness of the composite can increase 8.51% if 30% CMS rubber are added to the composite. The cause of the experimental results is analysised theoretically.
