Process for laying filaments on axesymmetrical convex surface, device for manufacturing and structure thus obtained.

摘要

- The method of the invention is a method for laying down filaments on a convex axisymmetric, especially hemispherical, surface (1) equipped with a circular hole or dead zone (4) centred on the pole (3), characterised in that a regular succession of points is defined on a reference circle (R) of the surface, the filament is presented successively in three geodesic trajectories (F1d, F1g, F1a) from a first starting point to a first finishing (arrival) point on the reference circle, the same laying-down procedure is reproduced for a second pair of starting and finishing points, so as to lay down a set of filaments called a ply (N1), then the same ply-laying-down procedure is repeated with a successive shift so that each point on the said reference circle (R) is, simultaneously and once, a starting point and a finishing point so as to obtain a layer and, possibly, the above procedure is started again until the desired thickness is obtained. - Application to the production of domed structures covered with strong fibres.
