Influence of Weaving Structure and Hybridization on the Low Velocity Impact Behavior of Woven Carbon-Epoxy Composites

摘要

In the current study, the low-velocity impact behavior of composite materials obtained from carbon and carbon-aramid hybrid woven fabrics produced in different constructions with the same yarn and under the same production conditions were determined, and the effects of weaving structure and hybridization on the low velocity impact properties were investigated. Depending on the weaving structure, the best results were obtained from twill woven composites. Energy absorption capacity was increased around 9-10% with hybridization. It was detected that peak load values changed with a coefficient between 0.84-0.97 in hybrid composites while changed with a coefficient between 0.49-0.87 in 100% carbon composites depending on bending stiffness.
