Disclosed is a process for producing composite board, and the said board is glass fiber reinforced magnesium cement board with wood grain. The process comprises two steps of preparing a mold with wood grain and preparing glass fiber reinforced magnesium cement board using the mold. The first step comprises forming film bearing wood grain, copying the wood grain onto mill rolls, and rolling the formwork with the mill rolls. The second step comprises steps of preparing MgCl2 solution, agitating the mixed raw materials to obtain slurry, conveying the molds, scratching the slurry, disposing the raw materials, rolling, separating, shelving, curing, impregnating the board into water to remove free MgCl2, cutting, spraying protecting-paint, and so on. The process can produce the board with three-dimensional appeal, wood grain similar to that of log, and beautiful appearance. The board produced by the process has advantages of fire proof, water proof, vermin proof, light weight, compression and bending resistant, high strength, no moss growing, and so on.
