Abstract
The ablative response at predetermined locations in a carbon-carbon reinforced composite material are selectively modified by one or more implants of a compatible, non-carbon material disposed at selected sites in the material. The implants of non-carbon material, which should have a melting point below the sublimation temperature of the surrounding carbon matrix and thermal expansibility having a force below the strength of the surrounding carbon matrix, preferably are arranged essentially parallel to one another at selected axial sites in the direction of expected thermal flux.
