Heating device for manufacturing carbon fiber composite core

Abstract

The invention relates to a heating device for manufacturing a carbon fiber composite core. The heating device comprises a quartz rod and an outer protection layer which are coaxially and horizontally arranged, wherein a cavity is formed between the quartz rod and the outer protection layer; an infrared generator is arranged between the quartz rod and the outer protection layer; the infrared generator is wound by a resistance wire along an outer surface of the quartz rod; the carbon fiber composite core runs through a through hole of the quartz rod; and the infrared generator generates intermediate wave infrared rays from 1 to 4mu m through the resistance wire to penetrate quartz or ceramic materials so as to generate a heat effect. The heating device has the advantages of a simple structure, high heat conduction speed, energy conservation and high efficiency.

Description

technical field [0001] The invention relates to a heating device, in particular to a heating device for manufacturing a carbon fiber composite core in a power transmission cable. Background technique [0002] In the process of manufacturing carbon fiber composite core, carbon fiber and other fiber composite materials need to be soaked and glued first, and then heated and cured. Traditional heating method: heat the metal shell, heat the metal shell through heat conduction, use the conduction heating of the air to heat the air in the cavity, and finally conduct heat conduction on carbon fiber and other fiber composite materials. It can heat, cure and dry carbon fiber and other fiber composite materials. During the conduction process, the temperature gradient of the object is used to conduct heat conduction. The speed is slow, the waste of heat source is serious, the time of heating, curing and drying is slow, and the productivity is low. Using the principle of infrared heat e...
