A fiberboard panel is formed from at least one corrugated sheet of molded cellulose fiber material having alternating ribs and grooves. Spaced slits are cut through the ribs on one face of the sheet and terminate short of the opposite face so as to form at least one slotted portion of more flexibility which may be bent to form a curve. The corrugated sheet is sandwiched between two flat sheets of the same material to form a composite panel. The corrugated sheet or panel is formed by a wet processing method including successive cold and hot press steps in which a wet mat is pressed between an opposing perforated platen and non-perforated, elastomeric material platen of cross-sectional shape substantially matching the desired panel shape and dimensions.

The invention belongs to the field of wood processing and discloses a method for manufacturing curved laminated veneer lumber. By the method, a plurality of layers of veneers are parallelly assembled, glued and hot pressed along the grains according to the following conditions: a, each veneer has the same breadth size and the moisture content of lower than a fiber saturation point; b, loose sides and tension sides or front sides and back sides of all veneers are kept in the same direction during parallely assembling; and c, one or more parameters of the veneers, such as the moisture content, thickness and density are increased or reduced layer by layer. In the method, the conventional plane hot press can be directly used without a die, so the production cost is saved, and the production cycle is shortened. As the bending of a product is determined by the nature of the laminated veneer lumber and is not influenced by the action of external force, the problem of serious resilience is solved, and sustained bending of the laminated veneer lumber can be realized.
