Abstract

In the current study the low-velocity impact behaviour of composite materials obtained from carbon and carbon-aramid hybrid woven fabrics of different constructions, produced from the same yarn and under the same production conditions, was determined, and the effects of the weaving structure and hybridisation on the low velocity impact properties were investigated. Depending on the weaving structure, the best results were obtained for twill woven composites. The energy absorption capacity was increased by around 9 - 10% with hybridisation. It was observed that peak load values varied with a coefficient between 0.84-0.97 for hybrid composites, whereas the range was 0.49 - 0.87 for 100% carbon composites, depending on the bending stiffitess.
