摘要

Process for manufacturing a composite material tube, device for implementing said process, and tube obtained The invention relates to a method of manufacturing a tube of composite material by winding reinforcing fibers (21) or layers (20, 30) of unidirectional reinforcing fibers embedded in a thermoplastic or thermosetting matrix, comprising depositing the fibers or sheets (20, 30), on a mandrel (1) rotated about its longitudinal axis (XX '), by means of at least one carriage movable along the mandrel (1). It consists of superimposing several distinct layers (2, 3), each layer (2, 3) consisting of fibers (21) or sheets (20, 30) arranged in all parallel helicoids. The helicoids of one layer (2, 3) have the opposite helix angle of that of the helicoids of the adjacent layer (s). Figure for the abstract: Fig. 1
