以Nomex蜂窝和新型自粘接预浸料作为试验材料,通过采用均压板的共固化工艺制备蜂窝夹层板.采用滚筒剥离方法测试其面-芯结合性能,采用电子显微镜等方法观察其蒙皮-蜂窝粘接面、剥离后蒙皮表面结构及蜂窝壁端面的微观形态,并测试了蜂窝壁厚度与蜂窝壁浸渍的树脂成分.结合以上测试结果研究了在采用均压板的制备过程中工艺参数和蜂窝特征对蜂窝夹层板面-芯结合强度的影响规律,并考察了蜂窝夹层板的粘接形式.结果表明:在采用均压板模具的共固化工艺中,一定的升温速率范围内,蜂窝板的面-芯结合强度随着升温速率的减小而增大；而加压时机对蜂窝板的面-芯结合强度的大小没有明显的影响；蜂窝壁端面越粗糙、蜂窝壁树脂层厚度越小,夹层板的面-芯结合强度越好.
