This project overcame the technical bottleneck that bamboo-based composites were difficult to be applied in load-bearing fields such as construction structures, vehicle and ship manufacturing. Four new materials, five new processes and seven sets of key technical equipment were developed:
1) For the first time, the concept of "in-situ restructuring of bamboo" was proposed, and two manufacturing technologies and key equipment for bamboo in-situ restructuring materials were developed: bamboo curved in-situ restructuring material and bamboo multi-directional in-situ restructuring material. The modulus of rupture (parallel, MOR∥) reached 140 MPa, and its physical and mechanical properties were better than those of ordinary solid wood.
2) An innovative manufacturing technology for bamboo OSB was developed. The MOR∥ of bamboo OSB material was 35.1 MPa, and the modulus of elasticity (parallel, MOE∥) was 5070 MPa. Its load-bearing performance exceeded the highest-grade OSB/4 standard specified in "Oriented Strand Board" (LY/T 1580-2000).
3) For the first time, the manufacturing technology of large-specification bamboo strip laminated lumber was developed. The MOR∥ of the material was 151.6 MPa, and the MOE∥ was 17793 MPa. Its load-bearing performance exceeded the standard specified in "Test Methods for Physical and Chemical Properties of Wood-Based Panels and Decorated Wood-Based Panels" (GB/T 17657-1999).
4) An innovative manufacturing technology for bamboo split-paired silk recombination material was developed. The MOR∥ of the material was 98 MPa, and the MOE∥ was 5800 MPa. Its load-bearing performance exceeded the standard specified in "Bamboo Plywood for Automobile Cargo Floor" (LY/T 1055-2002).

Major Achievements: Four sets of new equipment were appraised by the National Forestry and Grassland Administration as "strong in technological innovation, reaching international advanced level"; three sets of new equipment were appraised by Hunan Province as "filling domestic gaps, with product technology reaching domestic leading level"; one new process was appraised by Hunan Province as "ranking leading level in domestic similar research". Three sets of key technical equipment were recognized as provincial-level new products; four new achievements were registered by provincial and ministerial-level scientific and technological departments. 7 invention patents and 11 utility model patents were authorized. 3 industry standards were formulated, and 2 enterprise standards were promulgated and implemented. 15 national-level product and production line inspections and tests were passed. 1 monograph was published, and 38 academic papers were published. 8 scientific and technological novelty searches were conducted. 1 postdoctoral fellow, 4 doctoral candidates, 12 master candidates and a number of scientific research backbones were trained, forming a relatively stable high-level scientific research team.

The research results were popularized and applied in more than 10 enterprises including Zhenjiang Zhongfuma Machinery Co., Ltd. (Jiangsu), Qingdao Guosen Machinery Co., Ltd. (Shandong), Ningguo Zhongji Bamboo & Wood Products Co., Ltd. (Anhui), Hunan Hengdun Group Co., Ltd. and Zhuji Guangyu Bamboo Industry Co., Ltd. (Zhejiang). Three equipment manufacturing bases and six production lines have been built, directly providing nearly 3000 jobs. In the past three years, the newly added output value reached 1,550.4 million yuan, newly added profit was 187.44 million yuan, and newly added tax was 105.554 million yuan.

This project belongs to agroforestry non-wood material manufacturing technology, with distinct characteristics. It extends the industrial chain, cultivates new economic growth points in bamboo-producing areas, drives the economic development of vast bamboo-producing areas, plays a significant role in the upgrading of forest product industry, and has achieved remarkable economic, social and ecological benefits.
