Abstract
At least one layer of fibers of a material susceptible to heating by electromagnetic radiation is incorporated in a porous structure. The structure is subjected to the radiation to heat up the body which is contacted with hydrocarbon gas to cause the gas to deposit carbon within the porous structure and thereby cause densification.
