Abstract
A method for the densification of a porous structure comprises providing the structure with a body of material (13, 14) which includes a susceptor element foil (14) which is more susceptible to heating by electromagnetic radiation than the other material (13) of the body, exposing said porous structure to hydrocarbon gas and simultaneously applying an electromagnetic field to said porous structure whereby said susceptor element (14) at least in part causes heating of the porous structure to a temperature at which the gas infiltrating the porous structure deposits carbon within the porous structure.
