Abstract
A process for manufacturing a composite block of closed geometry, in the form of a continuous ring, based on reinforcing fibres and on a cross-linkable resin, by continuously winding in superposition a predetermined number Nc of layers of a tape of the reinforcing fibres embedded in a matrix based on a composition comprising the cross-linkable resin, the method comprising, from the upstream end downstream, the steps of: forming a tape made of the reinforcing fibres, the thickness of the tape being between 0.1 mm and 0.5 mm; depositing the tape on a support that dictates the final shape of the composite block, and winding the tape onto the support, in a single direction, by superposing the number Nc of layers in order directly to form the continuous ring on the support, Nc being less than 15.
