Thermal processing molding process of a carbon fiber material head-mounted audio-visual and communication equipment shell

Abstract

The invention discloses a carbon fibre material thermoplastic processing forming process for a head-mounted audio-visual and communication equipment shell. The carbon fibre material thermoplastic processing forming process adopts mould pressing forming and comprises the following steps: (1) preheating a mould, and then placing a customized carbon fibre plate on a lower mould; (2) heating the lowermould and an upper mould, and simultaneously, heating by using an infrared device; (3) pressing the upper mould and the lower mould, and keeping temperature and keeping pressure; and (4) cooling, demoulding, and then gluing, wherein the customized carbon fibre plate is obtained by weaving carbon fibre cloth first by carbon fibre filaments, dipping the carbon fibre cloth in thermo-reversible resin, and coating the upper layer and the lower layer of the outer surface of the carbon fibre cloth with customized special films, wherein the customized special films are resin films. According to the carbon fibre material thermoplastic processing forming process for the head-mounted audio-visual and communication equipment shell, a high-gloss shell is directly formed by using a sheet carbon fibre material in the mode of selecting a resin material and laminating the films by using specific resin films after the carbon fibre cloth is dipped and matching specific process conditions; and the shellis not required to the polished and ground completely after being formed, has a mirror surface effect naturally, and has uniform thickness and extremely good visual sense.

Description

Technical field [0001] The invention relates to the field of communication and audio-visual equipment, in particular to a new material production process for head-mounted equipment. Background technique [0002] For head-mounted communication and audio-visual equipment, due to their special use needs to be worn on the head, their weight, comfort, and appearance are all factors that need to be considered in the selection of materials and processes. [0003] The mature technology of the existing molded case is the use of plastic injection molding, but the weight of the plastic case is still relatively large, which will bring a heavier burden during long-term use, while limiting the increase in the functionality of the headset and the possibility of expanding the use scene Sex. In addition, surface treatment such as spraying is required in the later stage of processing, which will cause serious environmental pollution. [0004] Therefore, in general, the existing plastic head-mounted ...

Problems solved by technology

However, due to the special use requirements of the overall head-mounted device shell as an appearance part, especially such products usually belong to high-end demand fields, such as aviation, industrial and mining industries, petroleum industry and other professional fields, which have higher requirements for surface polishing. , the general molding process cannot obtain a high-gloss surface that meets the requirements for large-volume parts such as the housing of head-mounted communication and audio-visual equipment.

Therefore, for the overall appearance of the larger shell covering the ear, direct molding of carbon fiber materials has not yet been applied in the audio-visual industry.
