Abstract: A new type of fibreboard was manufactured by using the sludge recovered from alkaline hydrogen peroxide machine pulp(APMP)of poplar and Pinus massoniana fiber as the starting materials in this paper. Effects of the ratio of sludge dosage, UF resin content, and hot-press temperature on the mechanical properties of the sludge-fiber boards were investigated. Result showed that higher content of sludge resulted in higher IB, lower MOR and MOE. A sludge-fiber board could be produced MDF used for interior with 15% content of sludge, according with request of the Chinese national standard GB/T 11718—1999. The fiber board with 15% sludge could reduce the danger of the fire, the heat release rate and the mass loss rate of the board.
