摘要： A composite material for uses including stay cables and prestressing concrete comprises high strength wire strand coated and impregnated with an impermeable and strongly adherent epoxy based resin. Impregnation and coating are effected by passing a fully formed, cleaned, and heated strand (2) through a known electrostatic powder coating line (6) modified to include a mechanism (5) for temporarily opening successive sections of the strand such that the strand (2) passes into the coating line in an opened state, and the strand wires (12 and 13) are coated with a fused thermosetting epoxy resin before the strand (2) is reclosed, the resin filling the interstices in the reclosed strand (2a). The strand opening mechanism (5) includes a rotatable template (19) with wire guides (19a) for leading the outer spiraled wires (13) of the strand (2) temporarily away from the center wire (12).

摘要： Concrete strengthening members, particularly prestressing tendons such as strands of steel wire, are provided with a strongly adherent plastic coating which may be substantially impermeable for improved corrosion resistance, and/or which may have embedded therein abrasive or grit-form particles to provide improved bond with the concrete, and particularly to provide controllable bond transfer in prestressing tendons of the pretensioned type. The plastic coating preferably is applied electrostatically in powder form, and fusion bonded by heat. The abrasive can be applied by spraying during a viscous state of the heated resin, and can be varied as to size and spacing density so as to control the surface condition and the bonding effect. Fusion and curing heat may come from preheating of the member before application of the resin powder, which preferably is a heat curable, thermosetting epoxy. Coating thickness and grit application are readily variable to meet particular requirements. Particularly advantageous results are achievable for high strength steel strands for prestressing concrete by pretensioning, facilitating their use where previously considered impractical or impossible.
