Carbon fiber polymer composite materials, due to their low specific gravity, high modulus and strength, large design freedom, convenient molding, and integration of structure and function, have become representatives of lightweight and high-strength materials. These materials are increasingly being used in structures such as large aircraft, automobiles, and wind turbine blades. However, there are only a few domestic enterprises capable of producing high-strength and high-toughness carbon fiber polymer composite materials, which has become a bottleneck for the development of these industries. Professor Qiu Jun has been committed to the research of high-performance carbon fiber polymer composite materials, proposed the theory of nanostrengthening of polymer matrix materials, holds more than ten patents in this field, and has mastered the production processes and performance control methods of high-strength and high-toughness carbon fiber polymer composite materials that meet the needs of different industries. With funding from the National Eleventh Five-Year Plan 863 Program and the Ministry of Education's international cooperation projects, this project has made significant progress in theoretical foundations, The application research has gradually matured. High-strength and high-modulus carbon fiber polymer composite materials are mainly based on the patented technologies invented by Professor Qiu Jun, 'Preparation method of carbon fiber/carbon nanotube/epoxy resin multi-dimensional hybrid composite material' (ZL201010121917.9) and 'Preparation method of carbon fiber/carbon nanotube/bismaleimide resin multi-dimensional hybrid composite material' (ZL201010105610.x). According to these two patents, taking epoxy resin and bismaleimide resin as the research objects, based on the structural characteristics of the two resins, a structure with characteristic functional groups in organic diamines was introduced onto the surface of carbon nanotubes, resulting in an 'amine-functionalized multifunctional carbon nanotube modifier'. Through the chemical reactions between the organic diamine and both epoxy resin and bismaleimide resin, curing, toughening, reinforcement, and other effects were achieved. For the purpose of dispersion, etc., further by using carbon nanotubes-epoxy resin and carbon nanotubes-bismaleimide resin as matrices to composite with carbon fibers, carbon fiber/carbon nanotube-epoxy resin and carbon fiber/carbon nanotube-bismaleimide resin composite materials are prepared. During the processing, physical and chemical interactions occur between the three phases, thereby forming a synergistic reinforcement effect of carbon nanotubes and carbon fibers. This results in high-strength, high-toughness carbon fiber polymer composite materials with comprehensive properties such as ultra-high toughness, strength, stiffness, erosion resistance, corrosion resistance, and anti-aging performance. This technology belongs to the National 863 Project Plan, and its achievements have reached the international advanced and domestic leading level.
