摘　　要：以聚碳硅烷为前驱体采用PIP工艺制造陶瓷基复合材料构件,在裂解炉升温过程中,由于炉内温度场空间分布上存在的差异,以及炉内不同区域的实际升温过程相对于控温程序的滞后性,导致了裂解场分布不均匀。以聚碳硅烷热裂解动力学为基础,通过温度场与裂解度场的对应关系,阐述裂解度场的计算过程,并提出应用裂解度场的PIP工艺质量一致性控制方案。The use of polycarbosilane as precursor through PIP process to manufacture ceramic matrix composite component inpyrolysis furnace heating process, differences in the spatial distribution of temperature field as well as the furnace temperature program lag in different regions results in uneven distribution of the field of pyrolysis. Based on the polycarbosilane pyrolysis kinetics and correspondence between the temperature field and the field of pyrolysis, the calculation of the field of pyrolysis is described and the application of the field of pyrolysis to control the unity consistency in PIP process is proposed.
