摘要：为提高硅橡胶胶黏剂胶接石英陶瓷和碳纤维增强复合材料的强度和耐温性能,研究了胶接面湿热状态、打磨程度、胶层厚度、操作等待时间等工艺参数对胶接强度的影响。在试片正常烘干、打磨的情况下,当胶层厚度为0.4 mm、操作等待时间小于0.5 h时,胶接效果最优,其压缩剪切强度达到了3.06 MPa。探索了底涂剂处理对胶接强度和耐温性能的影响。在温度不高于100℃时,底涂剂A的效果较好。经底涂剂A处理后,胶接试片常温下的强度提高了13.7%,达到3.48 MPa;100℃时的强度提升率达到37.7%。在更高温度下,底涂剂B的效果更为显著。经底涂剂B处理后,胶接试片常温下的强度提升了10.1%,达到3.37 MPa;300℃时的强度提升了44.0%,达到1.57 MPa;200℃时的强度提升率最高,为49.0%。测试结果为高温条件下石英陶瓷胶接结构的胶接工艺优化及其应用提供了参考。
To increase the adhesive strength and the heat-resistance ability of the quartz ceramic and the carbon fiber reinforced polymer when the silicon rubber adhesive is used,the influence of process parameters,such as wet-hot state,grinding degree,adhesive thickness and waiting time before operation of the adhesive surface on the adhesive strength is studied.Under the condition of normal drying and grinding,when the adhesive thickness is 0.4 mm and the waiting time is less than 0.5 h,the best adhesive effect is obtained,and the compressive shear strength reaches 3.06 MPa.The influence of primer coating treatment on the adhesive strength and the heat resistance is further investigated.The effect of primer coating A is better when the temperature is not higher than 100 ℃ and the effect of primer coating B is more significant when the temperature is higher.After the treatment of primer coating A,the compressive shear strength increases by 13.7% and reaches 3.48 MPa at room temperature and the highest increase rate is about 37.7% at 100 ℃.After the treatment of primer coating B,the compressive shear strength increases by 10.1% and reaches 3.37 MPa at room temperature,and it increases by 44.0% and reaches 1.57 MPa at 300 ℃.The highest increase rate is about 49.0% at 200 ℃.The test result provides a reference for the optimization of the adhesive process and the application of quartz ceramic adhesive structure under high temperature.
