Embodiment

[0015] Embodiment: a kind of processing technology of carbon fiber product and glass fiber product, comprises the following steps:

[0016] ①. Pretreatment: Cut the carbon fiber prepreg or glass fiber prepreg into the required size and shape, and then stack the cut carbon fiber or glass fiber prepreg according to the thickness requirements;

[0017] ② Molding: Put the stacked carbon fiber prepreg or glass fiber prepreg into the mold, and the mold is evenly equipped with a heating channel, and the hot water is first passed into the mold for heating by using a rapid cooling and rapid heat conversion machine. In the channel, the temperature of the mold is raised to the set temperature, and then pressurized to the set pressure. After maintaining the pressure for a set time, cold water is passed into the heating channel of the mold to lower the temperature of the mold to the specified temperature, and then the mold is opened. Obtain carbon fiber semi-finished products or glass fibe...

Abstract

The invention discloses a processing techniques of carbon fiber products and glass fiber products, which comprises the steps of pretreating, molding, contouring and the like, wherein a quick cooling / heating conversion machine is used in the molding process to quickly heat and cool a mold, thereby shortening the molding time and greatly improving the production efficiency; in the molding process, the surfaces of piled carbon fiber prepregs or glass fiber prepregs are coated with release films, so that resin on the carbon fiber prepregs or the glass fiber prepregs can be transversely and uniformly leveled at high temperature and high pressure so as to obtain carbon fiber semi-finished products or glass fiber semi-finished products the surfaces of which are smooth and have no pits and pinholes, thereby reducing subsequent surface treatment difficulty, and saving the subsequent procedures and working time; and the surface of the mold used in the molding process is subject to mirror polish and electroplating treatments, so that the surface of the product produced by the mold has the highlight effect, the paint baking or other post-treatment technic of the product is omitted, the working time can be reduced, and the cost can be lowered.

Description

technical field [0001] The present invention relates to a processing technology of a product, in particular to a processing technology of a product mainly made of carbon fiber or glass fiber. Background technique [0002] The commonly used processing method of carbon fiber / glass fiber products is: slowly heat the formed carbon fiber / glass fiber prepreg to a certain temperature, keep it for 40-80 minutes, and then cool it naturally. The total molding time is at least 45 minutes. Moreover, during the high-temperature and high-pressure molding process, the epoxy resin on the surface of the carbon fiber / glass fiber cloth is affected by the high temperature, and it will undergo physical changes and flow slowly and be lost. Cavities will make the surface of carbon fiber / glass fiber semi-finished products quite unsightly, directly affecting the quality of carbon fiber / glass fiber products. Therefore, it is necessary to carry out surface treatment with paint to make carbon fiber / gl...
