【摘要】：為了研究碳纖維復(fù)合材料(CFRP)修補(bǔ)結(jié)構(gòu)在電熱載荷環(huán)境下的沖擊性能,采用自制的電熱損傷測(cè)試平臺(tái),測(cè)試了修補(bǔ)后CFRP層板在不同電流下試樣的表面溫度分布和電阻變化規(guī)律,對(duì)修補(bǔ)后CFRP層板進(jìn)行了低速?zèng)_擊和沖擊后剩余壓縮強(qiáng)度(CAI)測(cè)試,并對(duì)沖擊損傷失效特征進(jìn)行了對(duì)比分析。結(jié)果表明:低電流對(duì)修補(bǔ)后CFRP層板的抗沖擊性能影響較小,CAI呈現(xiàn)略微增長(zhǎng)的趨勢(shì);隨著電流強(qiáng)度的增加,電熱產(chǎn)生的高溫對(duì)修補(bǔ)界面層產(chǎn)生破壞,導(dǎo)致材料抗沖擊性能減弱,CAI明顯降低。
[Abstract]:In order to study the impact property of carbon fiber reinforced plastic (CFRP) repair structure under electrothermal load, the surface temperature distribution and resistance change of the repaired CFRP laminates under different currents were measured by using a self-made electrothermal damage test platform. The low speed impact and residual compressive strength of the repaired CFRP laminates were tested. The failure characteristics of impact damage are compared and analyzed. The results show that the impact of low current on the impact resistance of CFRP laminates is slightly increased with the increase of current intensity. The high temperature produced by electroheat destroys the interface layer, which results in the decrease of the impact resistance of the material and the decrease of CAI.
