【摘要】：利用固化動(dòng)力學(xué)模型對(duì)20mm厚度和3mm厚度的ZT7H/5429碳纖維復(fù)合材料層合板進(jìn)行了固化模擬,在固化過(guò)程中,20mm厚度平板出現(xiàn)了溫度峰值,中心溫度與表面溫度差不超過(guò)6℃,3mm平板溫度分布均勻,溫度歷程與熱壓罐工藝溫度基本一致。利用簡(jiǎn)化的溫度場(chǎng)和等效熱膨脹系數(shù)對(duì)60°和90°拐角的V型基準(zhǔn)試件進(jìn)行了固化變形模擬,并進(jìn)行了V型基準(zhǔn)試件的固化試驗(yàn)。60°和90°拐角試件的固化回彈角的模擬值分別為1.58°和1.18°,試驗(yàn)測(cè)得的回彈角的平均值分別為1.59°和1.11°。對(duì)V型復(fù)合材料蒙皮構(gòu)件進(jìn)行了固化變形模擬,并得到了補(bǔ)償過(guò)的工裝型面,在該工裝上成型的試件與設(shè)計(jì)形狀基本一致。
[Abstract]:The curing simulation of ZT7H/5429 carbon fiber composite laminates with 20mm thickness and 3mm thickness was carried out by using curing kinetics model. During the curing process, the temperature peak value of 20mm thickness plate appeared, the difference between central temperature and surface temperature was not more than 6 鈩，
