From shaoxing jiangnan branch co., LTD., Beijing ZhongFang fiber building technology co., LTD. Jointly completed "concrete reinforced polypropylene fiber and industrialization development of key application technology" project preparation of the three kinds of imitation of steel fiber can significantly improve the concrete performance of high-performance. The project research and development of the products is a new field of industrial textiles, application field is very wide. According to Beijing ZhongFang fiber building technology co., LTD., general manager of Shi Xiaoxing introduction, reinforced polypropylene fiber has become indispensable to large public buildings construction. In particular, the national stadium "bird's nest", Beijing Olympic park tennis center, CCTV headquarters building, Beijing metro line 4, the national conference center, the state general administration of sports training floor or national major projects such as Beijing can see the figure of reinforced pp fiber.

According to Shi Xiaoxing, using fiber reinforced concrete is not a new idea of contemporary, in the clay, lime, gypsum, cement and other cementitious materials to add fiber to improve its mechanical properties is a very old method. Chinese people already know more than three thousand years ago in the clay mixed with straw grass in order to increase the hardness and resistance to the ability of the rains washed out. Join MaGen in lime or gypsum application has more than two thousand years of history. Du pull companies in the United States made many contributions for China's large area USES polypropylene fibre.

After "concrete reinforced polypropylene fiber and industrialization development of key application technology" project after successful industrialization. Led by China textile academy of jiangnan branch, Beijing ZhongFang fiber building technology co., LTD. Of zhejiang shaoxing municipal science and technology "high-performance imitation steel fiber industrialization development and key technology of" science and technology development projects, also by the shaoxing municipal science and technology appraisal and acceptance of the organization. The product development and promotion of the use of toughening and crack resistance of concrete for construction has obvious effect, can significantly improve the toughness of concrete, to overcome the shortcomings of high strength and toughness of concrete is poor, so it is very beneficial for improving the durability of buildings.
