Abstract: The present invention concerns a method and apparatus (14a) for winding a section of each of one or more layers of material (18a) around a mandrel (30) and about a longitudinal axis of the mandrel (30), wherein each layer of material (18a) includes fibers and the winding is performed such that, for the wound section of each layer of material (18a), each of a majority of the fibers is angularly disposed relative to the longitudinal axis of the mandrel (30), and: (1) disposing a tape (82) over the layer(s) of material (18a) such that at least a portion of the tape (82) overlies at least a portion of the wound section of each layer of material (18a) and a long dimension of the portion of the tape (82) is substantially parallel to the longitudinal axis of the mandrel (30); and/or (2) spot-joining adjacent sections of the wound section(s) together.
