ス繊維製「板状体」は軽量である特徴を有する。(Prior art) A plate-shaped body (hereinafter referred to as a "plate-shaped body") obtained by pressurizing and heating a fiber mat such as a glass fiber mat containing an uncured binder to harden the binder has sound absorption and heat insulation properties. It is widely used as an interior material for buildings, vehicles, etc., and glass fiber "plates" in particular are characterized by their light weight.

うな問題点を有する。However, "plate-shaped bodies" generally have the disadvantage of low mechanical strength, especially bending strength, and if a load is concentrated on one part during handling, they are likely to break or peel off in that part, and this tendency is The smaller the thickness and density of the "plate-shaped body", or the larger its dimensions, the more significant the problem becomes. In order to increase the mechanical strength of the "plate-like body", has any method been proposed for reinforcing it by bonding reinforcing members such as FRP or metal plates to the "plate-like body" (Utility Model Publication No. 53-14493? (see publication), it has the following problems.
（１）「板状体」と補強部材が剥離し易い。(1) The "plate-shaped body" and the reinforcing member are likely to separate.
（２）「板状体」の単位面積当りの重量が大となる。(2) The weight per unit area of the "plate-shaped body" becomes large.

り易い。(3) If it is a "plate-shaped body" or a flat plate-shaped body, a reinforcing member and a fiber mat containing an uncured binder are layered together,
The binder is hardened and bonded by applying pressure and heat to form a "plate-shaped body" and is integrally bonded with a reinforcing member to form a reinforced "plate-shaped body".
It can also be used as a "plate-shaped body" (hereinafter referred to as a "reinforced plate-shaped body"). (Hereinafter, this method will be referred to as the integral molding method.) However, if the "plate-shaped body" has a curved shape, it is difficult to manufacture a reinforced plate-shaped body using the integral molding method. It is necessary to mold the reinforcing members separately and attach them together, which not only complicates the manufacturing process, but also makes it difficult to perfectly match the shapes of the two, and there is a gap between the plate and the reinforcing members. The formation of gaps and peeling tends to cause a decrease in strength.

ないことが見出された。By heating, the phenolic resin contained in the dried cloth is once softened and then hardened. Therefore, the cloth-like material can undergo sufficient plastic deformation before hardening, and therefore has good conformability to the mold and can be deep-drawn. At the same time that the resin contained in the dry cloth is cured by the crosslinking reaction, the resin contained in the mat is also cured by the crosslinking reaction. The resin contained in the dried cloth is B stage (resol), and the resin contained in the wood mat is A stage (resol).
In addition, this mat contains a considerable amount of water, and even though this mat has a larger weight per unit area and is thicker, both can be cured at the same time in a short time. It was found that both were strongly and integrally bonded and no peeling occurred.
