    摘要:

    聚酰亚胺复合材料因其优异的耐高温性能和机械性能,在航空航天领域获得了广泛应用,但复杂、高成本的热压罐成型工艺难以满足聚酰亚胺树脂基复合材料快速加工成型,限制了其进一步的应用。本文综述了适用于树脂传递模塑成型(RTM)技术的聚酰亚胺树脂及其复合材料的研究现状与发展趋势,重点论述了苯乙炔基封端的聚酰亚胺树脂及其复合材料的国内外研究情况,提高RTM技术成型聚酰亚胺树脂及其复合材料耐温等级的同时保持低充模黏度和高韧性将会是重要的发展方向。

    Abstract:

    Polyimide composites have been widely used in the aerospace field due to their excellent high temperature resistance and mechanical properties. However, the complexity and high cost of autoclave forming process make it difficult to meet the rapid processing of polyimide resin matrix composites, which limits its further application. In this manuscript, the research status and development trend of polyimide matrix resin and its composites suitable for RTM technology have been reviewed, with emphasis on the domestic and foreign research of phenylethynyl terminated polyimide and its composites.It is an important developing direction to improve the temperature resistance of RTM polyimide resin and its composites while maintaining its low molding viscosity and high toughness.
