Abstract

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
