Abstract

The invention provides a cable composite core with high temperature resistance, ageing resistance, high tensile strength, extremely high toughness, simple process and small equipment investment and a manufacturing method thereof. The cable composite core is formed by inner layer carbon fiber, outer layer glass fiber and mixed resin matrix adhered on the inner layer carbon fiber and the outer layer glass fiber in longitudinal directional distribution. The manufacturing method is implemented as follows: 1, preparing mixed resin and respectively pouring the mixed resin into three resin grooves; 2, placing the carbon fiber and the glass fiber on creels respectively, leading out by a yarn guide plate in a multi-beam manner, and drying by an infrared heater; 3, performing size soaking on the carbon fiber by an intermediate resin groove, performing size soaking on the glass fiber via the other two resin grooves at the two sides, and premolding; and 4, finishing moulding by a stock mould, entering in a thermocuring moulding mould for curing and moulding, drying, performing secondary curing, hauling by a hauling machine and rolling by a winding machine.

Description

technical field [0001] The invention particularly relates to a cable composite core and a manufacturing method thereof. Background technique [0002] The traditional cable core is a steel core, and the steel core cable has a small operating temperature range, a large expansion coefficient, and a low elastic modulus. The composite core is composed of at least one reinforcing fiber included in a thermosetting resin matrix, and has a higher modulus of elasticity and a lower coefficient of expansion at an operating temperature in the range of about 90-230°C. In CN1649718A there is provided "aluminum conductor composite core reinforced cable and manufacturing method", which includes longitudinally oriented and substantially continuous reinforcing fibers in a thermosetting resin matrix, capable of operating in the range of about 90-230°C. The method of manufacture is to provide a predetermined number of fiber bundles, direct the fiber bundles through a resin-filled dip tank, use ...
