Weihai Guangwei Composite Materials Co., Ltd. (stock code: 300699), is affiliated to Weihai Guangwei Group and is a high-tech enterprise specializing in the research, development and production of high-performance carbon fibers and composite materials. The company is under the jurisdiction of Weihai Tuozhan Fiber Co., Ltd., General New Materials Section, Weihai Guangwei Composite Materials Technology Co., Ltd., Weihai Guangwei Energy New Materials Co., Ltd., Weihai Guangwei Precision Machinery Co., Ltd., Weihai Guangsheng Aerospace Technology Co., Ltd., Inner Mongolia Guangwei Carbon Fiber Co., Ltd., Guangwei Beijing R&D Center and other units can provide customers with the integrated entire industry of "raw silk-carbon fiber-fabric-resin-precipit-composite material products-equipment manufacturing-testing and analysis-technical design" Chain service.

At the beginning of the 21st century, in order to solve the passive situation of foreign "technology, products, and equipment" of carbon fiber and the core technology being controlled by others, Guangwei Composite resolutely transformed from the traditional fishing gear industry to the high-tech new materials industry, and established Weihai Expanded Fiber in 2002. Co., Ltd., led by the founder Mr. Chen Guangwei, embarked on the road of carbon fiber research and development of "eliminating wealth and poverty, turning back without shore", using the meager power of a small fishing rod to realize China under the dilemma of no technology and equipment. The "from nothing" of carbon fiber has broken foreign blockades, changed the world's carbon fiber pattern, and has become the main supplier of carbon fiber in national defense and military industry.

The company's products mainly include GQ3522 (T300 level), GQ4522 (T700 level) QZ5526 (T800 level), QZ6026 (T1000 level), QZ6526 (T11000 level), QM4035 (M40J level), QM4050 (M55J level), QM3560 (M65J level) and various types of carbon fiber and composite materials such as QM5535 (M40X grade). The products are widely used in aerospace, weapons and equipment, wind power blades, photovoltaic thermal fields, high-voltage hydrogen storage, sports and leisure, building reinforcement and other fields.

The company has strong scientific research strength, with scientific research platforms such as the National Industrial Design Center, the National Enterprise Technology Center and Shandong Carbon Fiber Technology Innovation Center. As the developer of the national carbon fiber standard, it presided over the drafting of "Polyacrylonitrile-based carbon fiber" and "Carbon Fiber Prepreg" Two national standards, "Technical Conditions for High-Temperature Carbonizing Furnaces for Carbon Fiber Production" and "Technical Conditions for Graphite Furnaces for High-Module Carbon Fiber Production", participate in the formulation of national standards such as "Carbon Fiber Testing Standards". 755 patents are authorized.

Faced with the booming domestic industry and fierce global competition, Guangwei Composite takes the guiding principle of "jumping out of the courtyard wall and turning around the courtyard wall", insists on serving the country in industry, adheres to the development of its main business, and accelerates technological innovation and market investment. The company implements the "621" development strategy, namely, layout carbon fiber, general-purpose new materials (prepreg), energy new materials (carbon beams and other pultrusion products), advanced aviation composite materials, advanced aerospace composite materials, precision equipment (carbon fiber production equipment and Working mold) 6 business segments, driven by the two "industry, education, research and application" scientific research platform engines of the National Industrial Design Center and the National Enterprise Technology Center, form a competitive full industrial chain and establish a national advanced composite material field. Dominate the position and lead the high-quality development of the industry.
