The effect of temperature during impact on the compression after impact behavior of carbon/epoxy composite sandwich panels with Nomex honeycomb core is investigated. Impact tests were performed at room temperature, −70 °C, and −150 °C, while compression after impact tests on the damaged panels are performed at room temperature in order to isolate the effect of temperature during impact on the residual compressive strength and failure modes. Results show that there is almost no effect of target temperature at impact on the residual compressive strength of the damaged panels, although target temperature affects the damage induced by impact loading. Moreover, the effect of impact temperature on the residual compressive strength is negligible when compared to the strength reduction between pristine panels and the panels with the least amount of damage tested in this study.

研究了具有Nomex蜂窝芯的碳/环氧复合夹芯板的冲击行为后，冲击过程中的温度对压缩的影响。冲击试验在室温，-70°C和-150°C下进行，而受损板的冲击试验后的压缩在室温下进行，以隔离温度对残余抗压强度和破坏的影响。模式。结果表明，尽管目标温度会影响冲击载荷引起的破坏，但目标温度在撞击时几乎不会对受损面板的残余抗压强度产生影响。此外，
