Abstract : An investigation was made to develop a composite thermoplastic/glass filament reinforcement for buoyant submarine cables, and to design, develop and fabricate experimental and test models of wire and cables in 2000 foot lengths for use in improved floating wire submarine antenna systems. A new type glass tire-cord, with 3 strands, is somewhat stronger than the old 5 strand cord and has a significantly improved flex life. Its properties will be used as the new bench mark. To permit watertight packing of the impregnated tensile members, it may be necessary to start with wire-like, cylindrical shapes. From initial trials, it appears that the ribbon-like shapes, which are currently produced, can be converted into cylinders with the use of a roll-forming operation. No additives investigated to date significantly improved the properties of the polyurethane impregnated tensile members. Additives included coupling agents, Phenoxy, polysulfone, and a polyethylene interpolymer adhesive. No further work with additives is planned.
