Carbon fiber reinforced polyetheretherketone (CF/PEEK) composites with the advantages of high strength

low density

self-lubrication and workability

have great application value in the lightweight design of aircraft. In this study

the applicability of CF/PEEK composites in the design of filter assemblies is systematically studied to meet the needs of weight reduction and optimization. In order to ensure the service reliability of the aviation filter assembly

the sensitivity of design parameters to structural strength was analyzed for the main failure forms such as insufficient structural strength

vibration fatigue and screw thread loosening. The design scheme was optimized

then undergone simulation and strength evaluation. The effectiveness of the design scheme is verified by the vibration test

and the research results demonstrate that lightweight and high-reliability design of CF/PEEK composite aviation filter assembly can be achieved by structural optimization.
