Abstract
A laminated material in board form made by the steps of cutting open a lignocellulosic stalk in the fiber direction with a knife; flattening the lignocellulosic stalk by means of a roller press to form a compressed stalk, one face of which consists of its epidermis; arranging a plurality of the compressed stalks in parallel with each other to form a sheet; coating the sheet with a resin adhesive; stacking a plurality of the sheets coated with the adhesive; and then bonding with heat and pressure by means of a hot press. The laminated material has an equal to or higher flexural strength than conventional plywood or also has excellent sound absorbing and heat insulating properties in comparison with conventional particleboard or fiberboard.
