The fiberboard is also named as a density board, which is an artificial board made of wood fiber or other plant cellulose fiber as a raw material and urea formaldehyde resin or other suitable adhesives. During the manufacturing process, adhesives and/or additives may be applied. The fiber board has the advantages of uniform material, small longitudinal and transverse strength difference, difficult cracking and the like, and has wide application. The 1 cubic meter fiberboard needs 2.5 to 3 cubic meters of wood to manufacture, and can replace 3 cubic meters of sawn timber or 5 cubic meters of log. The development of fiberboard production is an effective way for the comprehensive utilization of wood resources.

The fiber board has the defects that the surface areas of the two sides of the board are different due to the reticulate pattern on the back surface, and the board is warped and deformed due to the difference of expansion force generated after moisture absorption; the hard board has hard surface, difficult nailing and poor water resistance. Dry-laid fibreboards, while avoiding some of the disadvantages, are relatively expensive.

From the view of the yield of provinces and cities, the yield of the fiberboard in Henan province in 2011 reaches 698 ten thousand cubic meters, which is increased by 44.87% compared with 2010 and accounts for 14.09% of the total yield of China. Followed by Guangxi, Jiangsu and Shandong, which account for 12.84%, 9.76% and 8.56% of the total yield, respectively. The production capacity of the fiber board in China in 1-7 months in 2012 reaches 29805100.39 square meters, and is increased by 11.3 percent compared with the production capacity in 2011, and the artificial board is made of lignocellulose fibers by interweaving and forming and utilizing the inherent adhesive property of the lignocellulose fibers. During the manufacturing process, adhesives and/or additives may be applied.
