A composite material comprising a silicone elastomer which is used in combination with another elastomer exhibiting properties which are complementary to those of the silicone elastomer, through the intermediacy of a means of attachment consisting of an elastomer which is interposed between the silicone elastomer and the other elastomer and which acts as a barrier for protecting the silicone elastomer, which material is characterised in that the intermediate elastomer is a heat-vulcanisable grafting elastomer, and this enables the interposed elastomer to act also as a layer for grafting the two outermost elastomers between which it is interposed. The process for the production of the composite material according to the invention consists essentially in subjecting the abovementioned heat-vulcanisable intermediate elastomer to a crosslinking treatment jointly and simultaneously with the outermost elastomeric components between which it is interposed. Application to the production of tubular structures such as pipes, tubes, thermal insulation sleeves and, in particular, connection hoses. |
