Abstract： Carbon fiber composites have the advantages of light weight and high strength when used in pressure-resistant structures， and defects generated during forming， processing， and service will have a negative impact on their performance. In this paper， the preset defect method is used to study the effects of defect area proportion， axial position and depth on the performance of thin-walled shell samples， and a simulation model is built to verify the adaptability with the measured values. The results show that the performance degradation caused by the defect area of 2% or less of the preset defective shell samples is covered up by process factors; the defect area of 5% or more has a significant negative impact on the shell performance; when the depth of the defect from the inner surface exceeds 1/2， the impact on the shell performance is significant; the simulation model has good compatibility with the shell samples.
