摘要：With pre-oxidized fiber integrated felt prepared by relayed needle punching process as preform and thermosetting resin as precursor, impregnation-curing-carbonization of resin-graphitization process was employed to prepare rigid carbon fiber integrated felt used for thermal insulation. Effect of every process including needle punching parameters, carbonization temperature, solution concentration and curing pressure on density was studied. Microstructure of samples was studied by using SEM. The results show that high values of needle-punching parameters lead to high values of preform density, carbonization temperature has little influence on density, but much influence on carbon content. Also solution concentration and preform density have a certain influence on density. What is more, with increasing curing pressure, the density of samples increases.
