Various winding forming processes of carbon fiber tubes

The winding molding of carbon fiber tube is to infiltrate the carbon fiber with resin or directly wind the carbon fiber prepreg on the core mold according to a certain angle and direction for heating and curing. The winding molding of carbon fiber tubes can be divided into three types: wet winding, dry winding, and semi-dry winding. This article will make a simple analysis of these three molding methods.custom carbon fiber tube

1. Wet winding

Wet winding is to wind the carbon fiber tow soaked with resin on the steel core mold by controlling the tension. This winding method can squeeze the air between the carbon fiber tows, effectively reducing the porosity of the product and increasing the sealing effect. and carbon fiber layout balance. In the process of production, the wear and tear of carbon fiber can be well reduced, the production speed can be accelerated, and the production cost can be reduced. This method also has limitations, such as poor selectivity of resin matrix, difficult control of product quality, and easy waste of resin raw materials.

2. Dry winding

Dry winding molding is mainly made of carbon fiber prepreg, which mainly heats the winding machine. When the carbon fiber prepreg is viscous, it is wound on the core mold. This molding method can adjust the formula and winding of the prepreg. The direction is controlled, so the quality of the produced products is easier to control, and the production efficiency is high, and the environment is clean and hygienic. But at the same time, the cost of production will also increase, and the degree of shear between the carbon fiber prepreg layers will also have an impact.carbon fiber sheets

3. Semi-dry winding method

The semi-dry winding method is to infiltrate the carbon fiber tow in the resin, place it in a winding machine for semi-drying, remove a part of the solvent in the carbon fiber tow, and then wrap it on the carbon fiber tube core mold. Compared with wet winding, this method can reduce the porosity a lot.

Due to the influence of a series of factors such as production process and production cycle, the winding and forming of carbon fiber tubes is mainly dry winding. At present, carbon fiber tubes made of carbon fiber prepreg are mostly circulating on the market.custom carbon fiber pool cue
