Carbon fiber molding

Join Date: 2020-02-07

Carbon fiber is a microcrystalline graphite material obtained by stacking organic fibers such as flaky graphite microcrystals along the axial direction of the fibers and performing carbonization and graphitization treatment. Carbon fiber not only has many excellent properties, such as high axial strength and modulus, low density, ultra-high temperature resistance in non-oxidizing environment, good fatigue resistance, small coefficient of thermal expansion and good thermal conductivity, It also has the softness and processability of textile fibers and is a new generation of reinforcing fibers.Due to the above characteristics of carbon fiber, it has been widely used in aerospace, automotive, military and other industries.

Three Common Processes of Carbon Fiber Molding

Compression Moulding
The carbon fiber prepreg is placed between the upper mold and the lower mold, the mold is closed, and the mold is placed on a table of the pressing machine. After curing the resin at high temperature and high pressure for a certain period of time, the carbon fiber product is removed. This molding technology has the advantages of high efficiency, good quality of parts, high dimensional accuracy and little environmental impact, and is suitable for the molding of compression parts with batch and high strength.

Winding molding
The carbon fiber prepreg is wound on the core of the mold according to certain rules. After a period of high-temperature curing, then demolding of form compression products. Carbon fiber winding molding can give full play to its characteristics of high specific strength, high specific modulus and low density. This molding process is usually used to manufacture pipelines.

Vacuum autoclave molding
carbon fiber prepreg is coated with vacuum, placed in autoclave and vacuumized by vacuum pump. After a period of vacuum heating, the resin is cured to obtain a carbon fiber product blank. The main advantage of this process is that high carbon fiber content composite material can be obtained. The resin can impregnate carbon fiber better.

Manufacture and Processing of Carbon Fiber Products:carbon fiber molding

1. Preparations
Cutting and laying prepreg, carbon fiber mold and other supporting work, and clean up the carbon fiber mold;

2. Mold filling and curing
Placing the stacked raw materials into the mold, closing the mold, applying certain pressure, temperature and setting curing time;

3. cooling and demolding
Cooling the mold after hot pressing treatment for a period of time to the mold, then opening the mold for demolding treatment;

4. processing and forming
The demolded product needs to be cleaned and polished to make the surface smooth and neat.

5. NDT and Final Inspection
The products will be inspected according to the requirements of design documents.
