Abstract (EN): The aim of this work is to assess the influence of high strain rates and testing temperature on the fracture energy in mode I, GIC, of carbon fibre reinforced plastic (CFRP) plates. Double cantilever beam (DCB) specimens were tested to determine GIC as a function of temperature (24 and 80 °C) under an impact load of 4.7 m/s (using a falling-wedge impact test machine), with the results being compared with the values previously determined by the authors under quasi-static loads. This work has demonstrated a significant influence of the testing temperature on the GIC of composite materials, as this value greatly increased for higher temperatures. On the other hand, a less significant influence of the strain rate on GIC was found, which slightly decreased by increasing the strain rate. © 2019 Elsevier Ltd
