Abstract
Method of forming a fiber-reinforced composite by applying multiple layers of prepreg material at the same time such that the proportion of unidirectional fibers which are orientated in the performing direction are greater than the proportion of unidirectional fibers which are obliquely orientated relative to said performing direction. This method controls the presence of overlaps, non-overlaps or gaps between the adjacent turns of the winding, thus improving the quality of the tube. This method also permits a reduction of the manufacturing costs. This method further enables production of tubes in a continuous way with different mandrels arranged to follow each other in a sequence which lead to an improvement of the production rate.
