摘要
通过不同尺寸的高温结构胶-双马基碳纤维层压板的二次胶接试验,对二次胶接过程中影响胶接内部质量和胶接强度的因素进行了分析。结果表明,在胶接反应过程中,复材板与复材板之间的实际配合间隙大于复材板制造的叠合公差,准确测量配合间隙及适当进行胶膜补充是提高胶接质量的重要保障,通过模拟胶接过程来测量配合间隙可行。对大尺寸胶接界面,通过提高胶膜的流动性能够提高胶接质量,但却降低了胶接强度。胶接强度随胶膜厚度增加而增加,但达到极值后随胶层厚度的增加而减小。
The factors in co-bonding process that influence the co-bonding quality and bonding strength were analyzed by co-bonding experiments between bismaleimide laminates of different size.It showed that the actual gaps between two laminates in the curing process were larger than the maximum sum of laminates tolerance.In a word,to measure the fitting gaps and make compensation to that were the key points for improve the bonding quality and it was a good way to measure the fitting gap by simulating the co-bonding process.Increasing the liquidity of adhesive film can improve the bonding quality,which decreased the bonding strength at the same time.The bonding strength increased with the increasing of film thickness,which decreased after reaching the peak value.
