纤维增强无机酚醛气凝胶复合材料超低温冷却加工试验

纤维增强类无机酚醛气凝胶复合材料，具有良好的隔热性能和质量轻的特点，是用于制作航天飞行器最外侧的热防护层的理想材料。但在常规加工中极易产生毛刺、撕裂等缺陷，利用大连理工大学自主研发的超低温内冷加工机床和内冷加工铣刀进行了侧铣加工试验，并以低损伤缺陷为目标对加工参数进行优化，结果表明超低温加工能够有效抑制上述缺陷的产生。Fiber-reinforced inorganic phenolic aerogel composites, which exhibit excellent thermal insulation properties and low density, are ideal materials for manufacturing the outermost thermal protection layers of aerospace vehicles. However, they are highly prone to defects such as burrs and tearing during conventional machining processes. Side milling experiments were conducted using the ultra-low temperature internal cooling machining machine tool and internal cooling milling cutter independently developed by Dalian University of Technology, and the machining parameters were optimized with the goal of minimizing damage-related defects. The results demonstrate that ultra-low temperature machining can effectively suppress the occurrence of the aforementioned defects.
