This project falls within the field of wood-bamboo composite materials and engineering. Supported by national key scientific and technological research and development projects under the Tenth Five-Year Plan, the Eleventh Five-Year Plan Sci-Tech Pillar Program, and the National High-Tech R&D Program (863 Program), and after 8 consecutive years of industry-university-research collaborative research, the project broke through major technical bottlenecks that had long restricted the development of China's bamboo industry. It invented high-performance bamboo-based composite manufacturing technologies, and developed 7 new products including container flooring, indoor and outdoor flooring, furniture decoration materials, and concrete formwork.

Starting from 2008, the project began applying for national patents. As of now, it has obtained 5 authorized invention patents, 8 authorized utility model patents, 3 published invention patents, and filed 2 international patent applications. Meanwhile, it has 2 achievements recognized by the Ministry of Science and Technology and the National Forestry and Grassland Administration, formulated 3 national and industrial standards, and published 17 research papers. A complete intellectual property system integrating technology research and development, patent application and standard formulation has been established.

Aiming at the technical bottleneck that bamboo green and bamboo inner layers are difficult to bond during the development of China's bamboo industry, the project invented the differential-speed asynchronous spot-cracking minimally invasive technology for bamboo green and bamboo inner layers, in-situ controllable fiber separation technology, fibrized veneer manufacturing technology, graded resin impregnation technology for reinforcement, and formaldehyde-free bamboo-based composite manufacturing technology. It developed a multifunctional bamboo veneer defibrator, established a bamboo-based composite manufacturing technology platform, and developed high-strength and high-weather resistance bamboo-based composites. The technical bottleneck of difficult bonding of bamboo green and bamboo inner layers was solved, increasing the primary utilization rate of large-diameter bamboo materials such as moso bamboo from 20-50% to over 90%, and enabling efficient utilization of small-diameter bamboo, clumping bamboo and other bamboo materials that were not previously industrially utilized.

The core of this technology lies in the invention of the bamboo fibrized veneer manufacturing technology, which breaks through the technical bottleneck of bonding bamboo green and bamboo inner layers, and developed two series of new products with high strength and high weather resistance. It adopts an enterprise-led, industry-university-research collaboration model for promotion and demonstration, to guide China's wood-bamboo industry towards high-tech content and high added value. It has realized large-scale industrial utilization of clumping bamboo, small-diameter bamboo and bamboo processing residues, promoted the upgrading and transformation of the bamboo industry, and enabled China's bamboo industry to maintain a leading position globally for a long term.
