摘　　要：根据真空辅助RTM工艺性特点,确定粉体填料改性树脂基复合材料工艺方法。将粉体填料分散于乙酸乙酯溶液中,并添加分散剂、黏结剂,并确定粉体填料与分散剂的质量比为1:0.5,制备一种分散效果较好的粉体填料悬浮液,将粉体填料定量喷涂增强纤维,并观察粉体填料喷涂量与喷涂速度之间成正比例关系。观察改性纤维SEM图,粉体填料能较好的黏附在增强纤维表面,且分布较均匀;改性后纤维由于粉体填料的涂覆效果,纤维丝断裂强力较无喷涂纤维丝下降10%,在一定条件下并不影响纤维增强复合材料性能。According to characteristics of vacuum-assisted RTM process,processing parameter of the powder filler introduced resin-based composite materials were detered. The powder filler is dispersed in ethyl acetate solution,disper- sant and binder were added to prepare a good dispersion of the powder filler suspension, and the quality of the powder fill and dispersant were detered to be 1：0.5. Quantitative spraying the powder filler reinforcement fibers in order to mod- ify the composite, and analysis the effection of the powder filler is dispersed in the solution and bonded state of the rein- forcing fibers. SEM observation reveal that the modified fibers,powder filler can relatively uniform adhesion in the fiber surface. Due to the powder filler adhesion in the fiber surface,breaking srength of failaments reduced about 10%.
