航发复材风扇机匣高温下包容性能的研究进展OA

During practical service,cold-end components such as fan cases operate at temperatures of 150-200℃.The fan case's ability to prevent blade shedding at these temperatures impacts the safety and reliability of aircraft operations.To this end,this paper comprehensively describes the research progress on the containment performance of composite fan cases in high-temperature environments,focusing on resin-based composite material types,manufacturing methods,containment definitions,design criteria,and high-temperature testing.It also summarizes and analyzes the damage and failure mechanisms of resin-based composites subjected to high-temperature impact,as well as experimental verification methods for composite impact resistance at high temperatures.Furthermore,it proposes prospects for verifying the containment performance of complete aircraft at high temperatures,aiming to improve the verification methods for the containment of composite fan cases.
