电热载荷对修补碳纤维增强复合材料冲击后压缩性能的影响
Effects of Electric-thermal Load on Residual Compressive Strength Repaired CFRP after Impact
摘要
Abstract
In order to investigate the impact performance of repaired Carbon Fiber Reinforced Polymer (CFRP) at electric-thermal load conditions,the electric-thermal load were performed on the repaired CFRP by the self-devised damage test device.The surface temperature field of the electrified specimens and the resistance variation with different current intensity were measured.The velocity impact and residual compressive strength after impact (CAI) of the electrified specimens were measured.The impact damage failure behavior was analyzed.The research results revealed that the effect on the impact properties is not so dominant when specimens electrified with low current that the CAI just increases slightly.With the increase of current intensity,the repaired interface layer property is destroyed by the high temperature of electric-thermal.The impact performance and CAI of electrified specimens are decreased obviously.关键词
