Carbon fiber composite materials have excellent properties such as light weight, high strength, high temperature resistance, wear resistance, fatigue resistance and high X-ray transmittance. They are now used as structural materials and are widely used in aerospace, automobile manufacturing, medical equipment, rail high-speed rail and other fields. It is very popular among people. With the development of technology, people's requirements for carbon fiber composite materials are also increasing. The following is a new trend of this new material technology.

In the future, the development direction of carbon fiber composite materials is: in the aspect of reinforcing materials, further improving the strength and modulus of carbon fiber and reducing the cost; in the aspect of resin matrix, mainly improving the compressive strength and heat and humidity resistance of the resin after impact; in the aspect of composite molding technology Further realize integral molding technology, curing monitoring, automation technology and 3D composite material technology, while improving composite material performance and reducing manufacturing costs.
 
1. Improvement of carbon fiber performance: In order to balance the strength, elastic modulus and cost, the compressive strength of carbon fiber needs to be improved, and the boron ion is accelerated under high voltage to make the crystal structure finer and the compressive strength can be improved by 1.3. ~2.0 times.
 
2, matrix resin technology: low temperature curing heat resistant resin, hot melt resin, non-combustible resin, carbon nanofibers with carbon fiber resin prepreg, improve the interlayer peel strength and compression strength.
 
3. Molding technology: Efforts to develop molding technology and intermediate materials that are high-speed, low-priced, and suitable for mass production. These technologies include: high-speed molding technology, resin infusion molding, resin film infusion molding (RFI), RTM molding, pultrusion, high-speed winding (FW) molding, SMC/BMC molding and other technologies.
