Abstract: The cable includes continuous glass filaments which are helically plied in rovings at a constant helical angle from cable center to outer surface and bonded together in elastomeric material. When heated, thermal elongation of the filaments is opposed by simultaneous radially directed thermal volumetric expansion of the elastomeric material. Thus, with respect to overall cable length, thermal elongation of the cable is opposed by a simultaneous increase in cable cross sectional area such that thermal elongation effects are controllable, dependent upon the thermal expansion properties of the filament and elastomeric materials used, by controlling the helical angle at which the filaments are plied to obtain either expanding, contracting or constant length cables, as desired. Thermal contraction effects produced by cooling the cable also are controllable by controlling the helical angle.

Abstract: The disclosure is of a high temperature resistant, composite yarn useful in the manufacture of woven and knitted fabrics for high temperature applications. The yarn of the invention comprises a core of a twisted, multi-filament or spun yarn and an outer coating or sheath of a high temperature resistant, synthetic, polymeric resin. The multi-filaments or staple fibers of the core are selected from high temperature resistant, synthetic materials. The outer coating comprises a plurality of coating layers intimately bonded to each other and to the twisted core so as to give the composite yarn of the invention an outward appearance and other characteristics of a monofilament. The composite yarn of the invention combines the properties of a monofilament and a multi-filament or staple yarn and is useful in weaving high temperature resistant fabrics.
