(57) [Summary]nThe carbon matrix composite comprises the following steps: 1) impregnating the fibrous material with a phthalonitrile thermoset polymer precursor, and 2) curing the product of step 1) to form a fiber reinforced thermoset polymer. And 3) pyrolyzing the product of step 2) to form a carbon matrix composite. The carbon matrix composite can be formed in only one working cycle of steps 1), 2) and 3). |
