Research Progress on High-Temperature Dynamic Mechanical Properties and Related Failure Criteria of Carbon Fiber Composites

The study of dynamic mechanical properties of carbon fiber composites and their failure criteria is essential for understanding and optimizing their properties, which can better predict the behavior of materials under extreme conditions, and improve the reliability and security in practical applications. Dynamic mechanical properties of carbon fiber composites at high temperatures are summarized from mechanical behaviour characteristics and failure criteria. It is pointed out that the influence of strain rate and temperature on dynamic mechanical behaviour of materials is the focus and difficulty of current research. Existing failure criteria for composites are summarized and differences in the applicability of these criteria are discussed. The study of mechanical behaviour under the coupled environment of temperature and strain rate, the establishment of relevant failure criteria and numerical simulation based on multiscale analysis methods are the focus of future research.
