縁抵抗が低下してしまう。BACKGROUND OF THE INVENTION Conventionally, as a nonwoven fabric used as a base material for the core layer of a composite epoxy resin laminate, a paper made by adding a binder to glass fiber has been used. Glass fiber does not have a good 1: retention property against epoxy resin, so when the epoxy resin absorbs moisture and swells, the laminate obtained by impregnating this nonwoven fabric with epoxy resin and molding it under heat and pressure will not react with glass fiber. The epoxy resin will peel off. Moisture then enters the interior due to capillary action, reducing the insulation resistance of the laminate.
その対策として、ガラス不織布にカップリング剤処理を
施し、その後エボキシ樹脂を含浸することが行なわれて
いる。As a countermeasure against this problem, the glass nonwoven fabric is treated with a coupling agent and then impregnated with an epoxy resin.
発明が解決しようとする課題
しかし、ガラス不織布を構戒するガラス１６Ｊｉ維は、
その表面にサイジング剤等の処理剤が梅さ？ているため
、その上からカップリング剤を於しても、その効果はあ
まりなかった。Problems to be Solved by the Invention However, the glass 16Ji fiber, which is used for glass nonwoven fabrics,
Is there a processing agent such as a sizing agent on the surface? Therefore, even if a coupling agent was applied over it, it did not have much effect.
本発明の課題は、ガラス不織布を積板用の部材として、
用いたとき、得られた積層板の絶紹抵抗の経時劣化を抑
制することである。The problem of the present invention is to use glass nonwoven fabric as a member for laminated boards.
When used, the objective is to suppress deterioration of the ultimate resistance of the obtained laminate over time.

ある。Means for Solving the Problems In order to solve the above problems, the method according to the present invention includes removing the sizing agent (used in the production of glass woven cloth) adhering to the glass fibers, and then The glass woven fibers are then treated with a coupling agent and bound with a binder to form a nonwoven fabric. A means for removing the sizing agent is, for example, heat treating the glass fibers.

形して製造する。A laminate is produced by impregnating the glass nonwoven fabric obtained as described above with epoxy resin, using it alone or stacking it in combination with another base material impregnated with epoxy resin, and then molding it under heat and pressure. .

繊維との親和性が必ずしも改善されているとはいえない
。Function Conventionally, in glass nonwoven fabrics, sizing agents remain attached to the surface of the glass fibers, and even when this glass nonwoven fabric is treated with a coupling agent, the thin layer of sizing agents becomes an obstacle, and the sizing agent remains attached to the surface of the glass fibers. It cannot be said that the affinity between the epoxy resin to be clarified and the glass fiber is necessarily improved.

としたときの吸湿による絶縁抵抗の経時劣化を抑制でき
ることになる。In the method according to the present invention, the sizing agent adhering to the surface of glass fibers is removed and the glass fibers are treated with a coupling agent. It will work effectively. That is, the adhesive force between the glass fiber and the resin increases, and it is possible to suppress the deterioration of the insulation resistance over time due to moisture absorption when the glass fibers are placed in a stack.

ンダも同時に除かれることが多く、ガラス不織布がその
形態をとどめにくくなるので適した方法とはいえない。It is also possible to remove the sizing agent after forming the nonwoven fabric, but in this case, the binder that binds the glass fibers together is often removed at the same time, making it difficult for the glass nonwoven fabric to maintain its shape, so this method is not suitable. I can't say that.

The glass fibers may be heated at a temperature of 350 to 800°C for 5 minutes to 48 hours. Heat treatment burns off the sizing agent and any attached organic substances. The coupling agent used to treat the glass fibers after the heat treatment is preferably an aminosilane coupling agent. Examples include 3-aminopropyltrimethoxysilane, 10-aminoundecyltrimethoxysilane, 3-aminopropyltriethoxysilane, and the like.
