摘要
首先明晰了环氧树脂、聚酰亚胺树脂、氰酸酯树脂化学结构与性能之间的内在关系,详细总结了上述树脂及其复合材料在飞行器中的应用情况、存在的主要问题以及改进方向。结合实际应用场景,基于自由基反应机理和扩散理论,重点阐述了环境条件(如温度、湿度、氧气含量、光照)等因素对材料老化以及性能退化的影响机制。从材料的化学结构和物理性能2个层面,结合仪器表征和分子模拟,全面介绍了导弹用复合材料失效的检测与评价方法以及各自优缺点。最后,展望了导弹用树脂及其复合材料性能改进的主要方法、失效机理的有效研究手段。
In this paper,the internal relationship between the chemical structure and properties of epoxy resin,polyimide resin and cyanate ester resin were firstly clarified.The application,main problems,as well as the improvement strategies of the above resin and resin-based composites used in missiles were summarized in detail.Based on the free radical reaction mecha-nism and diffusion theory,the influence of environmental conditions(such as temperature,humidity,oxygen content,illumina-tion)on material aging and performance degradation was emphatically expounded in combination with the actual application scenarios of missiles.Based on the chemical structure and physical properties of the materials,the failure detection and evaluation methods of composite materials for missile were introduced in combination with the characterization of instruments and molecular simulation.Finally,the main strategies for improving properties of resin and its composite materials for missiles and the effective means to study the failure mechanism were prospected.
