Abstract:
Polymer composites reinforced with carbon fibers coated with polybutadiyne and the coated fibers are described. The polybutadiyne coating is formed in a closely adherent film on or slightly below the surface of carbon fibers by substantially simultaneously vapor depositing and polymerizing butadiyne on the fiber.

Abstract:
A carbon-based composite is made by the steps of (1) impregnating a fibrous material with a phthalonitrile thermoset polymer precursor, (2) curing the product of step (1) 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).
