Mechanical properties of hybrid composites reinforced by carbon fiber and high-strength and high-modulus polyimide fiber

High-strength and high-modulus polyimide fiber is a kind of high-performance organic fiber rapidly developing in recent years. Taking advantage of its high strength and toughness and being combined with carbon fiber, it is expected to make a balance between stiffness and toughness, so as to afford a kind of structural composite with high strength and toughness. In this study, a series of hybrid fiber reinforced composites were prepared with...
