The modification process will lead to a qualitative leap, new processing ideas and ideas are constantly produced.3, The complex shaped construction of bionic design of product structure innovation is a breakthrough, fundamentally changing the traditional processing model Product structure from the common plate to the direction of multi-structure form.

It is mainly hollow - type barrel type LVL, anisotropic structure particleboard, local enhancement of unequal cross - section plate.4, dense micro - porous surface processing technology, wood compression and micro - hole technology developed rapidly, becoming a new"bright spot"of forestry industry.

The research of wood compaction is mainly focused on the compression and deformation of wood.Compression perpendicular to grain of wood research: the analysis of the compression perpendicular to grain of wood; Flat-bed press technology (lateral fixation techniques, bi-directional compression technology, part of the compression technology); Rolling technology; Water hydraulic technology.
