1. A composite material comprising:
a textile substrate having a surface, the textile substrate formed from a yarn, where the yarn is formed from a plurality of fibres or filaments, such that the yarn has a core region of fibres or filaments surrounded by a peripheral region of fibres or filaments; and
a cured elastomeric material layer laid over the whole or part of the textile substrate surface, wherein:
the cured elastomeric material penetrates into the yarn and is attached to the fibres or filaments in the peripheral region of the yarn; and
the cured elastomeric material is not attached to the fibres or filaments in the core region of the yarn,
wherein the cured elastomeric material is a silicone elastomer, and
wherein the silicone elastomer comprises a blend of a first and a second silicone elastomer, where:
the first silicone elastomer has: a pre-cured viscosity of from 100,000 to 300,000 centipoise at a temperature of 20° C.; a Durometer shore A hardness of from 5 to 20; an elongation to break of from 500 to 2000%; and a tensile strength of from 1 to 8 MPa; and
the second silicone elastomer has: a pre-cured viscosity of from 1,000 to 50,000 centipoise at a temperature of 20° C.; an Asker C hardness of from 10 to 25; an elongation to break of from 200 to 1500%; and a tensile strength of from 1 to 6 MPa.
