Research on Microscopic Morphology Analysis Model of Carbon Fiber

Abstract

The microstructure of carbon fibers with different properties also varies. Even with considerable mechanical properties, the microstructure characteristics of carbon fibers produced by different manufacturers or processes are different. Although current characterization testing methods can provide a fundamental analysis of the relationship between the microstructure and mechanical properties of carbon fibers, there is still no systematic theory on how to control the evolution of their microstructure during the production process of carbon fibers and develop high-performance and high-quality fibers. There is still a certain gap in the performance of carbon fibers in China compared to foreign countries. Therefore, this article analyzes and summarizes various publicly published models of carbon fiber microstructure in recent years, providing reference for establishing a recognized analysis model that can predict the mechanical properties of carbon fibers in engineering, providing effective direction for improving carbon fiber manufacturing processes, and providing technical support for developing high-performance and high-quality carbon fibers.
