摘要
对用于RTM工艺的 6 4 2 1双马来酰亚胺 (BMI)树脂体系的反应流变特性进行了研究 ,并根据流变特性确定RTM工艺的两个主要参数 :模具温度 110～ 14 0℃ ,注射压力小于 0 5MPa。结果表明 ,按此工艺条件可顺利成型先进RTM复合材料 ,且复合材料的表面质量良好、孔隙率低 ,达到先进复合材料的性能要求。
The curing properties and rheological behavior of 6421 BMI resin for RTM were studied with DSC and viscometer, respectively Based on these experimental results, two most important RTM processing parameters, the mold temperature and the injection pressure were determined When the temperature of mold is 110～140℃ and the injection pressure is less than 0 5MPa, the composite can be well RTM molded Both the surface quality and the void volume in the composite are satisfying Braided carbon composite samples were manufactured using the resin and RTM method The mechanical properties were evaluated
