摘要:
通过对成型工艺选择、模具结构设计及工艺参数的研究,探索了薄壁异形树脂基复合材料近净尺寸成型。研究结果表明,注料式模压克服了传统模压成型装料腔狭窄不易装料的问题,实现了薄壁异形树脂基复合材料的近净尺寸成型,极大地提高了材料利用率、降低了加工难度、缩短了成型周期。

Abstract:
Through forming process selection, mould structure design and process parameters optimization, the near net shape forming of the thin-walled profiled resin matrix composite is explored. The results show that the injection molding overcomes the problem that the charging chamber is narrow and difficult to load in the tradional molding process, and then, realize the near-net shape forming of thin-walled profiled resin matrix composites, which greatly improve the material utilization, reduce the difficulty of processing and shorten the molding cycle.
