<p>The membrane can for example consist of an assembly of panels (1, 5) of continuous resistant fibres, for example carbon, impregnated with a polymerisable synthetic resin, the membrane consisting of two layers (2, 6) of panels extending in a radial or virtually radial direction of the membrane and the resistant fibres of the other layer of panels being directed in a direction perpendicular or approximately perpendicular to the generatrices of the membrane. The method consists essentially in cutting out from a sheet of unidirectional fibres, and in the desired orientation, panels (1, 5), and in arranging them on the core of a heating mould in order to ensure the polymerisation of the resin. <IMAGE></p> |
