Effect of woven fabrics harness on the dynamic tensile mechanical properties of woven fabric composites

Woven composites are widely used in the composites industry. However, the type of woven fabricaffects the mechanical behavior of woven composites. Therefore, in this study, the tensile testing of glass/epoxywoven composites reinforced with three different types of glass woven fabric (harnesses of ۲, ۵, and ۸) has beencarried out at medium strain rates from ۱×۱۰-۵ s-۱ to ۷۰ s-۱ using a hydro-pneumatic dynamic testing machine.The experimental results showed that the tensile strength, tensile modulus, and fracture strain of wovencomposites with different harnesses increased by (۶۰.۱%-۶۰.۳%), (۲۴.۰۱%-۲۵.۱۹%), and (۲۸.۱۸%-۲۸.۲۴%),respectively. The result showed that although increasing the strain rate has increased the mechanical propertiesof the composite with different harnesses, the effect of changing the strain rate on the mechanical properties ofdifferent harnesses is almost constant.
