Three Elements Of Carbon Fiber High Temperature Compression Molding


High temperature compression molding is a commonly used molding process in the production process of carbon fiber products. The carbon fiber prepreg is placed between the upper and lower molds, and the mold is placed on the hydroforming table. After a certain period of high temperature and high pressure, the resin is cured. The carbon fiber part embryo body can be obtained. There are three elements that need to be paid attention to in carbon fiber molding. Let’s take a look at this article.
 
Temperature: The temperature control during molding mainly includes the molding temperature, the heating rate, and the molding curing temperature. When the material is put into the mold cavity, the temperature of the mold refers to the temperature of the mold, which mainly depends on the variety of the material and the quality index of the material. The temperature is also very important. If the temperature is too high, the cross-linking reaction of the material will start prematurely and the curing speed will be too fast, resulting in different curing of the inner and outer layers of the material in the mold cavity. The surface material will harden first, which will cause swelling and warping of carbon fiber products. warp deformation. When the molding temperature is too low, the fluidity of the material is poor, the curing speed of the material is slow, and the cross-linking reaction cannot be fully carried out, resulting in low strength of the product.
 
Pressure: The function of molding pressure is to overcome the vapor pressure generated by volatile substances in the material, to avoid defects such as bubbles, delamination, and loose structure of the product, and to increase the fluidity of the material, which is convenient for the material to fill all corners of the mold cavity. Make the product structure dense.
 
Time: The molding time is determined according to the size and difficulty of the product, and the curing time also needs to be determined according to the size and difficulty of the resin system product.

We are also able to handle larger production runs and provide a competitive pricing. If we don’t have the material or finish you require, we are more the willing to look at bringing it in for you.

What Is Carbon Fiber?Carbon fiber is made of polyacrylonitrile (PAN) (or pitch, viscose) and other organic fibers by carbonization (removal of most elements except carbon) by pyrolysis method under inert gas at high temperature above 1,000 °C. Inorganic polymer fibers with a carbon content of more than 90%.
