Bamboo is a very high quality design material, with natural good mechanical properties, high lateral compression resistance and bending resistance. It is widely used in household manufacturing. The current bamboo processing methods include cutting and crushing in large quantities, which seriously damage the natural hollow structure of bamboo, reduce the mechanical properties, and have low utilization. In view of the above problems, processing bamboo with the same diameter into an incomplete square prism, horizontal splicing and secondary veneer can produce a high‐strength composite board to improve the utilization rate of bamboo, which is of great significance for the efficient utilization of bamboo. This paper discusses the development of bamboo molding technology and the functional treatment of bamboo.
