摘要:
对J-133常温胶接蜂窝板的工艺特性进行对比分析,优选出合适的工艺方法,通过正交试验研究刷胶量、均压板厚度、打压压力对胶接质量的影响,优选出最佳的工艺参数,成功制备验证件。研究表明:最佳涂胶方式为“在面板胶接面依次涂胶,垫一层30g/m2碳毡,再刷上剩余胶液”;热压罐打压方式优于真空袋加压;在一定范围内的均压板厚度对蜂窝板的90°剥离强度影响最大,刷胶量的影响次之,打压压力影响最小;最优的工艺参数组合为:刷胶量350g/m2,均压板厚度为1.5mm,打压压力0.15MPa。根据最佳工艺参数制备出的J-133常温胶接蜂窝板,其胶接质量和力学性能与J78B胶膜中温固化的蜂窝板相近,满足航天设计要求。

Abstract:
The process characteristics of J-133 adhesive sandwich plate at room temperature were compared and analyzed. The suitable process method was selected. The effects of brushing amount, thickness of pressure equalizing plate and pressing pressure on the quality of bonding were studied by orthogonal test. Screen out the optimal process parameters and produced verification parts successfully. The research shows that the best way to apply glue is to “apply the glue on the panel’s adhesive surface, then put a layer of 30 g/ m² carbon fiber felt on the glue and brush the remaining glue”; the maximum effects on 90°peeling strength of honeycomb sandwich plate is the thickness of the plate, the second effects is the amount of brush and the pressure is the least; the best process parameters is that the amount of brush glue is 350 g/m²,the thickness of plate is 1.5 mm, the pressure is 0.15 MPa. According to the optimum process parameters, the quality of the honeycomb plate bonding at the room temperature meet the requirements of aerospace, which is similar to that bonding with heating.
