Abstract
The invention provides an anti-freezing cable core. The anti-freezing cable core comprises a aluminum alloy substrate and continuous carbon fibers, wherein the continuous carbon fibers take polyacrylonitrile as a raw material and have the strength of 5,600-6,200MPA; and the continuous carbon fibers are uniformly distributed inside the aluminum alloy substrate in parallel. The cable core is low in density, light in weight, high in strength and resistant to low temperature. The invention further provides a manufacturing method of the cable core.
