Abstract

The invention discloses a preparation method of a high-strength carbon-bonded non-metal reinforcing part. The high-strength carbon-bonded non-metal reinforcing part comprises aramid yarn, a carbon-bonded non-metal bonding layer and an extrusion molding layer, wherein the aramid yarn is located at the center, the aramid yarn is coated with the carbon-bonded non-metal bonding layer, and the extrusion molding layer is located at the outermost layer and covers the carbon-bonded non-metal bonding layer. The preparation method of the high-strength carbon-bonded non-metal reinforcing part comprises the following steps of A, taking aramid fibers; B, carrying out primary heating; C, carrying out soaking; D, carrying out drying and curing; E, carrying out secondary heating; F, carrying out extrusionmolding; G, carrying out primary cooling; H, carrying out secondary cooling; and I, carrying out winding. The high-strength carbon-bonded non-metal reinforcing part provided by the preparation methodhas high-strength tension stress, the melting point of the carbon-bonded non-metal bonding layer is relatively high, the carbon-bonded non-metal bonding layer is not prone to burning, the carbon andother compounds are inert at room temperature, and the structure is stable.

Description

technical field [0001] The invention relates to a strengthening member for an optical cable, in particular to a preparation method of a high-strength carbon-bonded non-metallic strengthening member. Background technique [0002] Many cables, such as fiber optic cables, generally include a strength member comprising at least one fiber or bundle of fibers. The reinforcement typically comprises one or more of glass fibers, aramid fibers, carbon fibers, etc. in a polymer matrix of epoxy, polyester, vinyl ester, polyolefin, acrylic, etc. Fiber and polymer selection is based on the desired characteristics of the reinforcement including, but not limited to, modulus of elasticity, tensile strength, and coefficient of thermal expansion. [0003] One method of making reinforcements is resin-wetting enabled pultrusion (resin-wetting enabled [0004] pultrusion). The method comprises the steps of wetting the fibers in a resin bath followed by consolidating the resin on the fibers in ...
