ABSTRACT:
A laminated material comprises a plurality of straight portions of vegetable stalks, each having an epidermis mainly of lignocellulose and a porous core. These vegetable stalks straight portions are impregnated with a thermal hardener solution of high-molecularizable liquid compound, resinified liquid, or mixtures thereof, arranged in parallel to form a layer of a sheet-like material, piling these sheet-like materials and pressing them to make these layers come to contact closely in flat condition. It is possible to make the directions of vegetable stalks in the sheet-like material different from the neighboring layers in order to strengthen a bending strength and other physical strength of the piled multi-layer laminated material, such as a pillar-like laminated material. Such pillar-like material is made by using a pair of pressing female mold and male mold, vegetable stalks being placed in the female mold and hot-pressed. After these vegetable stalks are laminated, the resin compound in the thermal hardener solution is set or harden.
