This paper focuses on the tensile behaviours of Kevlar 29 and 49 fabrics reinforced polymers (AFRP-K29 and-K49) at four strain rates (25, 50, 100 and 200 s−1) and five temperatures (−25, 0, 25, 50 and 100 °C). The experimental results show that the tensile mechanical properties of two types of aramid fibre-reinforced polymer (AFRP) are strain-rate dependent in terms of Young’s modulus, tensile strength and toughness at 25 °C. While the changes of mechanical properties except for the Young’s modulus of both AFRPs and the tensile strength of AFRP-K29 under different temperatures (−25, 0, 25, 50 and 100 °C) are not significant at the strain rate of 25 s−1. The failure patterns of AFRP samples are similar at the strain rates and temperatures investigated. Non-uniform strain fields on AFRP specimens were identified by digital image correlation (DIC) technique.
