| titleOfInvention | Vacuum Press Impregnation Carbonization for High Density Carbon / Carbon Composites |
| abstract | The present invention relates to a vacuum pressure impregnated carbon number (VPIC) for densifying a carbon / carbon composite material, and in order to densify a carbon fiber preform or a carbonaceous material (10), the reaction vessel (12) with a pitch (11). After being put into the reactor, it is mounted in the reactor (2) and impregnated by heat and pressurization. In the state in which the reactor (2) is made in a vacuum, a large amount of volatiles are generated from the pitch (11) while the viscosity of the pitch After performing the first heating step of heating up to a temperature T 1 to be lowered, pressurizing to a predetermined pressure P 2 and continuously heating up to maintain a constant temperature at a temperature T 2 at which the melt viscosity is the lowest. And performing a second heating step for cooling, and then performing a third heating step for coking the impregnated pitch by pressurizing it to a higher power force (P 3 ) and heating up the temperature. With the constitution, the densification process can be carried out at a relatively low pressure, thereby reducing energy consumption and economically easily carried out by low-cost equipment. Nevertheless, the impregnation efficiency can be raised above the conventional high temperature static pressure impregnation carbonization method. It can be. |
