Abstract

Impact damage is a major target in designing advanced composite materials reinforced with 3D knitted structures because composites are often used in applications which imply dynamic loads. 3D knitted fabrics present a large range of applications in the technical field, including advanced composites. Textile reinforcements are known for their unique combination of light weight, controlled anisotropy, formability and flexibility, as well as their strength and toughness. Epoxy and polyester composite materials reinforced with sandwich knitted fabrics made of Kevlar®, Twaron® and linen yarns are developed in the paper. Low velocity impact behaviour of composite materials reinforced with 3D weft knitted fabrics is modelled using the Taguchi method based on orthogonal arrays, in order to maximize the composite characteristics significant for this type of impact. The theoretical results obtained were validated by experimental data..
