Problems solved by technology

[0002] Existing carbon fiber composite materials need to be molded in a high-temperature reactor in their preparation, which has a long manufacturing cycle, high cost, and great limitations. For example, the finalization of small products and the shell of experimental prototypes cannot achieve fast Efficient preparation, and requires a lot of manpower and material resources
The defects of its carbon fiber material in its preparation process prolong the development cycle of new products and hinder the rapid development of this field in practical applications

example 1

[0021] Include the following steps:

[0022] 1. Preparation of FRP mold;

[0023] 2. Carry out fine treatment on the surface of the mold, that is, polish it to a mirror state, and maintain the cleanliness, dryness and smoothness of the mold;

[0024] 3. At room temperature, spray release water or release wax on a soft cloth. The model of release water is national standard 67# release water. Use a soft cloth with release water to wipe evenly on the surface of the mold;

[0025] 4. After the mold is left to stand for 30 minutes, use a clean soft cloth to wipe the surface of the mold, and then use a soft cloth with release water to wipe the mold again. When using release wax, the mold is left to stand for 15 minutes;

[0026] 5. Repeat steps 3 and 4) three to five times, and the last time the mold is still for 30 minutes when using the release wax;

[0027] 6. Spray the gel coat evenly on the mold; when the pressure of the air compressor is above 8kg, the nozzle diameter of the...

Embodiment 2

[0037] 1. First prepare the FRP mold. The surface of the mold needs to be finely processed to achieve the best mirror effect. The mold needs to be clean, dry and bright.

[0038] 2. Prepare imported glass fiber reinforced plastic release wax, recommend 8#, 333#, 102#, 104# (high temperature), or release agent, usually require high release mold frequently, you can use imported PMR high-efficiency release agent (international Standard 67# mold release water) or Denos MR578.

[0039] Apply wax with a soft, clean cloth. Use circles to ensure that the entire surface of the mold is completely and evenly waxed; after waxing is generally dry for 30 minutes, wipe it off with another clean cloth. It is better to repeat 3-5 times for a new mold.

[0040] High-efficiency mold release agent is much faster. Wipe it with a clean cotton cloth or spray it with a well-atomized spray gun to form a continuous wet (not dripping) film on the entire mold surface, and wipe it off with another piece ...

Abstract

Provided is a method for manufacturing a carbon fiber resin matrix composite. The problems that an existing technology for producing the carbon fiber composite is too high in needed cost and long in production period are solved. According to the technical scheme, products are produced with low cost within a short time. The method has the beneficial effects that the carbon fiber composite products can be manufactured at room temperature without high temperature and high pressure, and closely-closed production facilities are not needed. Product molding is fast, and the cost is low. The development of the products in the field can be effectively promoted.

Description

technical field [0001] The invention belongs to the technical field of composite materials, in particular to a method for manufacturing carbon fiber resin-based composite materials. Background technique [0002] Existing carbon fiber composite materials need to be molded in a high-temperature reactor in their preparation, which has a long manufacturing cycle, high cost, and great limitations. For example, the finalization of small products and the shell of experimental prototypes cannot achieve fast Effective preparation, and need to spend a lot of manpower and material resources. The defects of its carbon fiber material in its preparation process prolong the research and development cycle of new products and hinder the rapid development of this field in practical applications. Contents of the invention [0003] The object of the present invention is to provide a manufacturing method of carbon fiber resin matrix composite material. [0004] The object of the present inve...
