「問題点を解決するための手段」
本発明は、未硬化の結合剤を含むマット状の硝子繊維と
金属箔とを重ね一対の型で挟圧、加熱する際に、金属箔
を予め展延可能な形状としておくことを特徴とする。"Means for Solving the Problems" The present invention is a method of rolling out the metal foil in advance when stacking the matte glass fiber containing an uncured binder and the metal foil and pressing and heating them with a pair of molds. It is characterized by having a possible shape.
「作用」
一対の型で挟圧、加熱する際に、金属箔が展延して金属
箔とモールド品とがよく馴染むと共に、金属箔の破れが
防止される。"Function" When the metal foil is pressed and heated with a pair of molds, the metal foil spreads and the metal foil and molded product fit well together, and the metal foil is prevented from tearing.
「実施例」
第１図に示すように、金属箔１１と、未硬化の結合剤を
付与した硝子繊維１２とを重ね合せ、雌型１３と雄型１
４とからなる一対の型で挟圧、加熱して、未硬化の結合
剤を硬化させる。"Example" As shown in FIG.
The uncured binder is cured by pressing and heating with a pair of molds consisting of 4 and 4.
金属箔１１としては例えばアルミニウムなどが使用され

い。In addition, although the uncured binder is not particularly limited,
For example, a phenolic resin binder is used. As the glass fiber, for example, a single glass fiber is used. The amount of uncured binder applied is preferably about 10% by weight, for example. The matte glass fibers 12 preferably have a thickness of about 5 to 50 mm and a density of about 25 to 250 kg/rn'.
雌型１３と雄型１４とによる挟圧、加熱は、例えば圧力
１〜２０ｋｇ／ｃｒｎ’、温度１８０〜．３００℃程度
で１〜５分間程度行なうことが好ましい。The clamping pressure and heating by the female die 13 and the male die 14 are performed at a pressure of 1 to 20 kg/crn' and a temperature of 180 to 100 lbs., for example. It is preferable to carry out the heating at about 300° C. for about 1 to 5 minutes.

なものとなる。As shown in FIG. 4, the molded product 21 thus obtained has a shape that fits the female mold 13 and the male mold 14, and has a metal foil 11 adhered to the surface of the matte glass fiber 12. . Moreover, as shown in FIG. 5, the overall shape has a complicated shape with a plurality of convex portions 22 and concave portions 23, but due to the above-described spreading of the metal foil 11, the metal foil 11 is not torn. Since it adheres closely to the glass fiber 12, it has a beautiful appearance.
