| Abstract: |
| The service performances of composite equipment are heavily determined by the manufacture-induced defects. It is important to develop the advanced internal defect testing technique and evaluation method for the safety design of aerospace equipment. This paper provides an overview of advanced characterization techniques and evaluation methods for internal defects in resin matrix composites, focusing on the composite manufacture processes and typical internal defects, internal ex-situ and in-situ testing methods for composite defect detection, and methods for analyzing and evaluating the internal defects effects. Based on the current research status of composite defects, it is evident that computed tomography and image-based numerical computation methods are emerging in the characterization and analysis of composite defects with their unique advantage of accuracy. Meanwhile, the development trend of advanced characterization techniques and accurate computational analysis methods for composite structure safety design and reliability analysis in aerospace equipment are prospected. |
