Method of manufacture of composite materials, which has to be efficiently elastomers silicones together by a surface treatment and insulating composite materials thus obtained

摘要

The present invention relates to a method of manufacture of composite materials consisting of: / p & & p & 1.a coating the surface of a silicone elastomer of a thin layer of a solution in at least one organic solvent at most 15% by weight of a polymer metylhydro - genopolysiloxanique; 2.a ensure drying of the layer filed to the ambient air for more than 3 hours; 3.a applied on the layer 2 dried in a composition organopolysiloxane hardening in elastomer by a reaction of addition; 4.a allowed to harden the wrapper in the composition 3 in the elastomer. / p & & p & application of the process of the invention is the manufacture of ferrules in the field of electrical insulation.
