This study was conducted to improve the adhesion strength between a propellant, liner, and heat‐resistant material. As the drying time of the heat‐resistant material increased, the adhesion strength between the propellant, liner, and heat‐resistant material improved. Further, the surface of the heat‐resistant material was subjected to buffing treatment to improve the adhesion strength. In addition, as the thickness of the heat‐resistant material increased, the adhesion strength degraded. Moreover, the adhesion strength was improved by increasing the thickness of the liner on the heat‐resistant material. Besides, the adhesion strength slightly reduced with an increase in the plasticizer content. The liner curing time was an important factor affecting the adhesion strength, and an optimum liner curing time was obtained. In this study, the adhesion strength was improved by applying a barrier coat between the heat‐resistant material and liner. The adhesion was further improved when the heat‐resistant material was buffed.

提高复合固体推进剂，衬里与耐热材料之间粘结强度的研究

进行这项研究是为了提高推进剂，衬里和耐热材料之间的粘合强度。随着耐热材料的干燥时间的增加，推进剂，衬里和耐热材料之间的粘合强度也随之提高。此外，对耐热材料的表面进行了抛光处理以提高粘合强度。另外，随着耐热材料厚度的增加，粘合强度降低。此外，通过增加耐热材料上的衬里厚度可以提高粘合强度。此外，随着增塑剂含量的增加，粘合强度略有降低。衬垫固化时间是影响粘合强度的重要因素，并且获得了最佳的衬垫固化时间。在这个研究中，通过在耐热材料和衬里之间涂一层阻隔涂层，可以提高粘合强度。抛光耐热材料后，附着力进一步提高。
