Abstract
A composite glass fiber cable is disclosed having a negative linear coefficient of thermal expansion which is controllable by variation of the .Iadd.helical angle or angles of .Iaddend.twist of helically plied glass roving to substantially zero change in length over a wide variation in environmental temperatures under varying load conditions. .Iadd.It is possible, by controlling the helical angle and maintaining it constant from the cable center to outer surface, to control thermal elongation effects on the cable to obtain either expanding, contracting or constant length cables over a wide temperature range. .Iaddend.
