Description
Summary: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.
