The failure modes of aerospace J18DMA series crimping cable were studied. Guiding by the GJB5020-2001 standards, the resistance and tensile strength of the failed cable were statistically investigated. For some abnormal failure, the failure mechanism of the crimping cable was studied by using metallographic analysis. Finally, the results and the solutions were discussed.
