STUDY ON PROPERTIES OF CARBON FIBER-ARAMID FIBER HYBRID COMPOSTIES

摘要

With epoxy resin as matrix, seven types of pressure vessels (a carbon fiber reinforced composite, an aramid fiber (AF) reinforced composites and five carbon/AF hybrid composites with different ply types and hybrid ratios) were fabricated. The strength and strain behavior of these vessels are investigated. The results show that the strength of vessels with the same kind of fiber in longitudinal has a positive hybrid effect, and the strength of vessels with different kinds of fibers in longitudinal is low and has a negative hybrid effect. All hybrid fiber composite vessels have higher stiffness and lower axial strain than pure AF reinforced composites vessels.
