Mechanical Properties of Carbon Fiber Felt Reinforced Composites.

Abstract

The carbon fiber reinforced composites were fabricated by using as the preform the felts produced by the needle punching of the alternate stack of carbon fiber webs and carbon fiber woven fabrics. The influences of the needle punching density and the style of the woven fabrics on the mechanical properties of the composites were investigated. The interlaminar and the damage tolerant properties of the composites were markedly improved with increasing needle punching density although there is some trade-off in their tensile properties.
