A three‐dimensional fine‐woven punctured felt green body was used as a preform to generate an advanced ceramic. After chemical vapor infiltration and several cycles of precursor infiltration and pyrolysis, the pyrolysis carbon, as well as the silicon carbide and zirconium carbide ceramic matrix were formed. The advanced ceramic composite was tested under a hybrid fuel firing environment (hydrogen peroxide/ hydroxyl‐terminated polybutadiene, H₂O₂‐HTPB) for a relatively long time (240 seconds) as the puncture fibers head to the firing direction. After the test, beaded and bald fibers could be identified, and the sphere particles of firing residuals sizing from 10 μm to 1 mm were found. The test results show that the material is capable of withstanding a severe firing environment up to 2 MPa with an average linear erosion rate of 0.082 mm/s.

细织刺毡预成型高级陶瓷复合材料，可进行长时间混合燃料燃烧测试

使用三维精细编织的刺穿毛毡生坯作为预成型件来生成高级陶瓷。经过化学气相渗透和前体渗透和热解的几个循环后，形成了热解碳以及碳化硅和碳化锆陶瓷基体。在混合燃料燃烧环境下（过氧化氢/羟基封端的聚丁二烯，H ₂ O ₂‐HTPB）相对较长的时间（240秒），因为穿刺纤维朝着发射方向前进。测试后，可以识别出串珠和光头纤维，并且发现了烧成残留物的球形颗粒，尺寸从10μm到1 mm。测试结果表明，该材料能够承受高达2 MPa的严酷烧成环境，平均线性腐蚀速率为0.082 mm / s。
