摘要: 随着国产民机复合材料构件批产和服役,复合材料构件损伤失效问题正逐步显现,对现有设计、成型工艺、制孔、装配、检验和验收要求及规范构成了挑战。为进一步合理控制批产质量,减少服役损伤,在建立构件设计、制造、服役原始数据平台,研究构件损伤演化失效机理和技术图谱的基础之上,建立了构件损伤失效分析评价量化机制,结合飞机起落架外舱门损伤评价量化分析探讨了机制可行性,为复合材料构件批产质量优化提供新的思路,促进构件设计、工艺、检验、验收要求或标准优化。

Abstract: With the production and service of composite components for domestic civil aircraft, the problem of damage and failure of composite components is gradually emerging, which poses challenges to the existing design, molding process, hole making, assembly, inspection, acceptance requirements, and specifications. To further rationalize the control of quality and reduce service damage, a quantitative mechanism for component damage failure analysis and evaluation has been established based on the establishment of a raw data platform for component design, manufacturing, and service, and the study of component damage evolution failure mechanism and fractography. Combined with the quantitative analysis of the damage evaluation of the outer hatch of the landing gear, the feasibility of the mechanism is explored, which provides new ideas for the optimization of batch production quality of composite components and promotes the optimization of component design, process, inspection and acceptance requirements or standards.

Key words: composites, damage analysis, evolution, quantification
