されている。Due to the tight wood situation and the demand for effective use of raw wood, a medium-quality fiberboard (hereinafter referred to as "MDF") made by heat-pressing and laminating wood fibers with a special adhesive is widely used. However, this MDF has a smooth surface and has a beautiful finish when painted or overlaid with a vinyl chloride sheet, decorative paper, etc. In addition, there is no cracking when a name wood veneer is applied as a lumber board. Due to its excellent secondary processing characteristics, it is mainly used for various furniture materials such as wedding sets, mirror stands, sideboards, etc., as well as materials for light electric appliances such as TV cabinets and speaker boxes.
しかしながら、現在のＭＤＦは上述した家具などの非構
造用材として利用できるが、構造用建材として利用でき

に広くなる。Therefore, if the physical properties such as bending rigidity, wood screw holding force, and dimensional stability can be improved and the guarantee in terms of strength can be ensured while maintaining the good secondary processing properties inherent in MDF, it is possible to obtain a non-structure. Not only can it be used as a construction material, but it can also be used as a structural building material, and its range of use will be dramatically expanded.
本発明ではこれらの点に着目し、ＭＤＦの物理特性を改

提供することを目的としたものである。The present invention focuses on these points and aims to provide a composite plate that can be widely used by improving the physical properties of MDF.
そこで本発明はＭＤＦの両表面近くに、ラワン等の単板
を介在させることにより、ＭＤＦの物性を補強して上述
した課題を解決したものである。Therefore, the present invention solves the above-mentioned problems by interposing a single plate such as lauan near both surfaces of the MDF to reinforce the physical properties of the MDF.
即ち、比較的厚手のＭＤＦ基板の両面に木質補強板を接

一体的に圧着されたものである。Hereinafter, the structure of the present invention will be described more specifically based on the embodiments shown in the drawings. 1 is a substrate made of MDF having a thickness of 12 mm, for example, and wood chips are finely disintegrated fibers like cotton. It is formed by a usual manufacturing method in which an adhesive is applied and these are hot pressed and molded. 2 is a wood reinforcing plate such as a 3 mm thick lauan veneer that is crimped to both sides of the substrate 1 and 3 is a 3 mm thick MDF surface plate formed in the same manner as the above substrate. 2 is integrally crimped to each outer surface.
尚、図中４はＭＤＦの熱圧・成板時に板の表裏面に滲出
・硬化した接着剤によって成型された岩盤層を示す。In the figure, reference numeral 4 denotes a bedrock layer formed by an adhesive that has exuded and hardened on the front and back surfaces of the plate during hot pressing and forming of MDF.

のである。As shown in the table below, the composite plate has the wooden reinforcing plates 2 and 2 near the surface thereof, as shown in the following table, for example, bending strength and rigidity, length expansion coefficient due to water absorption / moisture absorption, length due to moisture release. Normal physical properties such as shrinkage and wood screw holding power
It has been experimentally confirmed that it is significantly improved compared to.
尚、上記物性データー表の複合板の数値は、単板の繊維
