ることが行なわれている。2. Description of the Related Art Conventionally, as a non-woven fabric used as a base material of a core layer of a composite epoxy resin laminate, a paper made by adding a binder to glass fiber is used. Since glass fiber does not have good wettability with epoxy resin, a laminate obtained by impregnating this non-woven fabric with epoxy resin and subjecting to heat and pressure molding is
When the epoxy resin absorbs moisture and swells, the glass fiber and the epoxy resin are separated from each other. Then, from there, moisture enters even inside due to the capillary phenomenon, and the insulation resistance of the laminated plate decreases. As a countermeasure, a glass nonwoven fabric is treated with a coupling agent and then impregnated with an epoxy resin.

ある。Means for Solving the Problems In order to solve the above-mentioned problems, the method according to the present invention is a method of removing a sizing agent (used during the production of glass fibers) attached to glass fibers and then cupping the glass fibers. Treat with ring. Then, the glass fibers are bound with a binder to form a non-woven fabric. A means for removing the sizing agent is to heat-treat glass fiber, for example.

い。Action Traditionally, glass nonwoven fabrics have sizing agents attached to the surface of the glass fibers, and even if this glass nonwoven fabric is treated with a coupling agent, the thin layer of the sizing agent becomes an obstacle and is impregnated thereafter. It cannot be said that the affinity between the epoxy resin and the glass fiber is improved.
