Abstract:

A carbon-based composite is made by the steps of 1 impregnation a fibrous material with a phtbalonitrile thermoset polymer precursor, 2 curing the product of step I to form a fiber- reinforced thermoset polymer and 3 pyrolyzing the product of step 2 to form the carbon- based composite. The carbon-based composite may be made with only one cycle of the steps 1, 2, and 3.
