Document Type and Number:
Japanese Patent JP2957829
Kind Code:
B2
Abstract:
Process for the preparation of a composite material made up of a vulcanised elastomer containing carboxylic acid or dicarboxylic acid anhydride functional groups, in combination with a thermoplastic elastomer containing polyamide blocks, characterised in that an elastomeric composition comprising the vulcanisable elastomer, a crosslinking system and optionally various adjuvants is vulcanised in a mould, part of which is occupied by the said thermoplastic elastomer containing polyamide blocks, the vulcanisation temperature being between -15 DEG C and +5 DEG C in relation to the Vicat point of the said thermoplastic elastomer containing polyamide blocks, the elastomeric composition and the vulcanisation kinetics being such that the material exhibits a cohesive rupture when stressed with the separation of the two elastomers. This process produces composite materials exhibiting excellent properties, especially tensile strength (cohesive rupture). The invention also relates to the composite material thus formed and its application to sports articles produced with the aid of these materials.
