| Abstract: | Deposition process and principle of chemical liquid thermal gradient densification is analyzed briefly for the preparation of carbon carbon composites. A kind of liquid carbon source is used as precursor in this new densification process and gradient heating is employed for a rapid densification.Experimental results show that chemical liquid thermal gradient densification process can increase the density of carbon matrix very quickly(2.5h) compared with conventional chemical vapor densification process. |
