Processing mold used for carbon fiber complex core pressing moulding

Abstract

The invention relates to a processing mold used for carbon fiber complex core pressing moulding. The processing mold comprises a horizontally arranged mold. A cylindrical surface of the mold is provided with an infrared generator which is formed by winding resistance wire around the cylindrical surface of the mold. A carbon fiber complex core runs through a through hole of the mold. A shape of the through hole of the mold can be set as a round shape, a square shape, an abnormal shape, a plate shape or other shapes. At six surfaces of the carbon fiber complex core or one surface combined with other random surface, a mold through which an infrared spectrum (1 micron to 4 microns) can penetrates is provided. The processing mold of the present invention has the advantages of simple structure, high precision, energy saving and high efficiency.

Description

technical field [0001] The invention relates to a processing mold, in particular to a processing mold for pressing and forming a carbon fiber composite core in a power transmission cable. Background technique [0002] In the process of manufacturing carbon fiber composite cores, carbon fiber composite cores include various fiber-reinforced composite materials (fibers refer to long fibers and short fibers of inorganic fibers, organic fibers, natural fibers, and metal fibers; composite materials refer to thermosetting and thermoplastic types. Composite materials), the mold is formed by drawing and extrusion, and the fiber-reinforced composite material is heated and solidified by heating the metal mold or heat-melted and then solidified. The heat conduction process makes the temperature of the pre-impregnated fiber-reinforced composite material Due to the conduction of heat energy from the surface to the inside, there is a difference between the inside and the outside, which is...

[0002] In the process of manufacturing carbon fiber composite cores, carbon fiber composite cores include various fiber-reinforced composite materials (fibers refer to long fibers and short fibers of inorganic fibers, organic fibers, natural fibers, and metal fibers; composite materials refer to thermosetting and thermoplastic types. Composite materials), the mold is formed by drawing and extrusion, and the fiber-reinforced composite material is heated and solidified by heating the metal mold by means of heat conduction or heat-melted and then solidified. The heat conduction process makes the temperature of the pre-preg Due to the conduction of heat energy from the surface to the inside, there is a difference between the inside and the outside, which is likely to cause the bonding stress between the fiber and the resin, and the uneven thermal curing and thermal melting of the composite material. At the same time, the thermal expansion coefficient of the metal mold is large, resulting in fiber reinforced composite products. Larger forming errors, difficult drawing and extrusion, poor material consistency and reduced strength, etc.
