Abstract The present invention provides a fibrous composite rope suitably used as a prestressing member for PC structures. The present invention features in one aspect such a fibrous composite rope. excellent in mechanical strength, fabiricated by heating the thermosetting resin-impregnated fiber cores so as to semicure the resin, then wrapping a primary wrapping and a secondary fiber bundles around the periphery of each said fiber core, stranding a plurality of the resultant fiber cores together into a rope form, and subsequently heating the stranded rope to complete the curing. In another aspect, the present invention provides a fibrous composite rope, in which either the primary or secondary wrapping fiber bundle is wound with wrapping clearance so as to form a rugged peripheral surface to improve adhesion to an anchoring means, as is required for a prestressing member.
