摘要
采用共固化和共胶接两种不同工艺条件制备了M40J级碳纤维/双马树脂基复合材料层合板,研究了两种工艺对复合材料层合板层间性能和胶接质量的影响。结果表明,共固化工艺制备的复合材料层合板的Ⅰ型临界应变能释放率(简称临界G_(ⅠC))和II型临界应变能释放率(简称临界G_(ⅡC))比共胶接工艺分别低8.4%和8.7%,但共固化工艺的Ⅰ型扩展应变能释放率(简称扩展G_(ⅠC))和Ⅱ型扩展应变能释放率(简称扩展G_(ⅡC))比共胶接工艺分别高24.0%和15.9%。此外,共胶接工艺层合板的胶层厚度比共固化工艺厚,更容易发生内聚破坏,且破坏主要发生在胶接层界面。
M40 J carbon fiber reinforced bismaleimide composite laminates were prepared by two different processes of co-curing and co-bonding.The influence of the two processes on the interlaminar performance and bonding quality of the resultant composite laminates were studied.The results show that the modeⅠcritical strain energy release rate(short as critical G_(ⅠC))and modeⅡcritical strain energy release rate(short as critical G_(ⅡC))from the co-curing process are 8.4%and 8.7%lower than that of the co-bonding process,respectively,while the extended G_(ⅠC)and G_(ⅡC)from the co-curding process are 24.0%and 15.9%higher than that of the co-bonding process.Furthermore,the results indicate that the adhesive thickness of the composite laminates from co-bonding process is higher than that of the co-curing process.Moreover,cohesive failure prefers to appear when the co-bonding process is adopted and the failure mainly occurres at the bonding interface.
