Document Type and Number:
Japanese Patent JP2004522867
Kind Code:
A
Abstract:
A method for the production of a multifilament carbon fibre-based longitudinal reinforcing element, designed to be incorporated in a rubber-based item. Said method comprises the following steps, whereby untwisted carbon fibres are plunged into an impregnating bath contained a solution of resorcinol-formaldehyde resin and rubber latex, the impregnated fibres are then dried and the dried fibres are subsequently twisted. The inventive method is characterised by the fact that it also comprises a step, during the impregnation step, consisting in opening out the carbon fibres by spreading out the constituent filaments thereof in such a way that each fibre has an increased surface area on which the impregnation can be performed.
