Manufacturing technology of bamboo engineering materials for construction

I. Technical Overview

The manufacturing technology of bamboo-based engineering materials for construction is a structural composite material manufacturing technology developed by the Research Institute of Wood Industry, Chinese Academy of Forestry. It uses bamboo as raw material and undergoes a special recombination process. The main products are of two types: bamboo-based engineered lumber for building structures and bamboo-based panels for building envelopes. Bamboo-based engineered lumber uses laminated bamboo strips as structural units and is mainly used for structural components of buildings, such as beams, purlins, rafters, and columns. Bamboo-based panels are mainly used for wall panels, roofing panels, and floor slabs. Currently, this technology has obtained four invention patents, implemented one forestry industry standard and one national standard, and won the first prize of the National Science and Technology Progress Award (one of the award-winning achievements).

II. Technical Features

Bamboo laminated timber technology uses bamboo strips as basic units, which are then glued, assembled, and hot-pressed to create structural bamboo laminated timber. This laminated timber is then graded, assembled, and glued together to form engineered timber. The product exhibits stable performance and excellent bending, compressive, and tensile strength, making it suitable for load-bearing components such as beams, purlins, trusses, and columns in buildings. Bamboo-based panel technology for building envelopes uses bamboo mats, bamboo blinds, or bamboo shavings as primary units to create high-strength panels suitable for wall panels, floor panels, and roof panels in buildings.

III. Market Prospects

During the "15th Five-Year Plan" key project period, the Research Institute of Wood Industry of the Chinese Academy of Forestry developed a manufacturing technology for bamboo-based engineering materials for construction. Permanent and temporary building demonstrations were conducted in Yunnan, Beijing, Sichuan, Wuhan, and other locations to meet the diverse construction needs. my country has abundant bamboo resources, and the implementation of this technology can provide customized options for promoting the development of domestically produced wood structures.
