 On June 28, Li Bo, member of the Xinxing Party committee and deputy general manager of Shaanxi investment group, together with relevant personnel from the strategic planning department, went to Xi'an Jingwei new city to investigate a new carbon / carbon composite company and had in-depth exchanges with the founder of the company on further cooperation planning and other issues.
       C-C composite or carbon carbon composite material is a carbon matrix composite reinforced by carbon fiber and its fabric. It has the advantages of low density (<2.0g/cm3), high strength, high specific modulus, high thermal conductivity, low coefficient of expansion, good friction performance, good thermal shock resistance and high dimensional stability. It is now one of the few candidate materials used above 1650 ℃, and the highest theoretical temperature is as high as 2600 ℃, so it is considered to be one of the most promising high-temperature materials. Due to its unique properties, carbon / carbon composites have been widely used in aerospace, automotive industry, medicine and other fields, such as rocket engine nozzle and throat liner, thermal protection system of space shuttle end cap and wing leading edge, aircraft brake disc and so on.
       During the meeting, Li Bo made a general introduction to the establishment background, development process and development status of Shaanxi investment emerging, and focused on the company's existing industrial layout in the composite industry and the future 14th five year development plan. Li Bo expressed the hope that the two sides can cooperate and complement each other in the future, make good use of their advantages in industry, capital, policies and supporting facilities, strengthen exchanges in the field of high-end composite industry, and maintain a long-term close cooperative relationship.
