Abstract (en)
[origin: WO9415015A1] This invention relates to a complex fiber string used as a tension member of a PC structure. The characteristics of the present invention reside in that it provides a complex fiber string having a high mechanical strength and produced by heating a thermosetting resin-impregnated fiber core so as to put the thermosetting resin in a semi-hardened state, subjecting the outer circumferential surface of the fiber core to primary wrapping and secondary wrapping with bundled fiber yarn, intertwining a plurality of fiber cores thus obtained, and then heating the intertwined fiber cores so as to harden the semi-hardened thermosetting resin. Another characteristic of the present invention reside in that the bundled fiber yarn for the primary or secondary wrapping of the fiber core is wound therearound in a spaced manner so as to form helical ridges and grooves on the outer circumferential surface of the fiber core, whereby the bonding strength required by a final product as a tension member with respect to a material to which the tension member is to be applied is improved.
