ABSTRACT:
Process for manufacturing tubes of a composite material from a preimpregnated fibrous reinforcing sheet whose width is split into a strip portion and a casing portion, where the thickness of the sheet is slit in the casing portion. A mandrel is inserted into the casing portion and rotated to cause the strip portion to be rolled around the mandrel, and the rolled strip and mandrel are placed into a plastic case for cross-linking. The process can be applied to the manufacture of tubes of small diameter, such as fishing rods, golf clubs and boat masts, and to the manufacture of porous tubes for use as a filtering material or filter membrane support.
