1. A process for producing a carbon reinforced preform of continuous fiber useful in the manufacture of carbon reinforced composite articles, comprising steps of:

  • (a) dispersing a catalyst precursor throughout a preform of continuous fiber;

    (b) converting said catalyst precursor into catalytic particles, said catalytic particles dispersed throughout the preform; and

    (c) contacting the preform of continuous fiber containing the catalytic particles with a hydrocarbon gas whereby vapor grown carbon nanofibers are deposited in situ at the catalytic particles throughout the preform to yield a carbon reinforced preform of continuous fiber.
