The aim of this study is to investigate the effects of different impregnation carbon fiber surface states on the longitudinal strength, interlaminar shear strength, composite density and fatigue performance. Surface state different carbon fiber base belts were prepared using the prairie seeding method, and then physical treatment, chemical treatment, plasma spraying and other methods were used for impregnation treatment on their surfaces. Finally, composite material samples were prepared using a textile machine and their mechanical properties were tested.The results showed that different impregnation methods had a significant impact on the performance of composite 精品文档---下载后可任意编辑materials.
