Abstract

Abstract: Carbon fiber composite materials have poor resistance to high-velocity impact, which to some extent hinders further expansion of application, so the hybrid design of carbon fiber and other fibers in composite materials is an effective measure to improve the comprehensive performance of composite materials. The investigation of static and dynamic mechanical properties exhibits C/EP possesses better static mechanical properties, while F12/EP has better dynamic mechanical properties. Based on automated fiber placement, structure design and the control of mass ratio for aramid fiber/carbon fiber, a novel carbon/aramid fiber hybrid composite combined with excellent mechanical property and high-velocity impact resistance has been prepared. The preferred mass percentage of aramid fiber for the hybrid composites is 35%~55%. The morphology analysis and simulation analysis for the sample after impact, the damage area of front plate and back plate for C/EP is obviously smaller than that for F12/EP, which indicates that F12/EP possesses better ability for impact energy dissipation, resulting in a higher criticalpenetration velocity.

Key words: carbon fiber, aramid fiber, hybrid composites, hybrid proportion, high-velocity impact resistance
