Problems solved by technology

[0014] In addition, when a conventionally known transparent thermoplastic film is used instead of such a resin material, the thickness of the transparent layer can be ensured. Poor adhesion between woody materials made of permanent resins creates a new problem of breakage or peeling of the transparent layer (thermoplastic film)

Abstract

A formed ligneous body having a clear layer integrally formed on the side of its front surface, with a predetermined thickness and a high degree of adhesiveness, and a decorative design surface presenting a deep and excellent appearance, and a method of advantageously producing a formed ligneous body presenting an excellent decorative design. The formed ligneous body (10) has a ligneous substrate (12) whose front surface serves as the decorative design surface (16) and the translucent clear layer (14) integrally formed on the decorative design surface (16), wherein the ligneous substrate (12) is formed by subjecting a ligneous material impregnated with a thermosetting resin material to a flow molding process, and the clear layer (14) is formed by heating / pressing at least one fibrous sheet constituted by plant fibers and impregnated with a thermosetting resin material, together with the ligneous material during the flow molding process, so that each of the fibrous sheet is made transparent.

Description

technical field [0001] The present invention relates to a wooden shaped body and a manufacturing method thereof, and more particularly to a wooden shaped body formed with a deep appearance surface, and a method of advantageously manufacturing the wooden shaped body. Background technique [0002] Conventionally, wooden molded objects formed from various wood materials such as wood and bamboo have been widely used as structural materials for furniture and daily necessities in addition to floors for construction. For example, even in the field of automobiles, as the intention to upgrade is increasing, automotive interior parts with a woody feel are preferred. In order to meet such requirements, wooden molded articles are also used as outer panels or Surface panels, etc. [0003] Then, as such a wooden molded article or its manufacturing method, in Japanese Patent No. 4502848 (Patent Document 1) and Japanese Patent No. 4849609 (Patent Document 2), a wooden molded article useful...
