Description of the Related Art Conventionally, a glass fiber woven fabric and a core material for a surface material have been used in the production of a laminated board (CEM-3) for electrical insulation, which uses a glass fiber woven fabric and a glass fiber nonwoven fabric in combination as a sheet-shaped substrate. The glass fiber non-woven fabrics are produced separately. Further, the steps of manufacturing a prepreg by impregnating and coating a resin varnish on these sheet-shaped substrates are also performed separately. In order to improve the increase in the number of steps, it has been proposed to integrate the periphery of a predetermined number of prepregs to improve the handling property, and then subject the prepregs to heat and pressure molding (Japanese Patent Application Laid-Open No. 2004-242242).

Alternatively, the glass fiber base material is manufactured by further stacking a glass fiber woven fabric on the papermaking surface of the manufactured glass fiber base material and integrating them with a binder. The method for producing a laminated board according to the present invention comprises heating and pressing a prepreg obtained by impregnating and coating a resin varnish on the glass fiber base material.

Therefore, the glass fiber woven fabric and the glass fiber nonwoven fabric will be handled as one,
It is possible to improve the efficiency of the impregnation coating of the resin varnish on the base material and the step of stacking a predetermined number of prepregs prepared thereby (weighing step). Further, the glass fiber base material produced by the method according to the present invention, the glass fiber produced and the glass fiber of the glass fiber woven fabric are bound with a binder,
The glass fibers of the woven glass fiber itself are also fixed with a binder. Therefore, it is possible to suppress the displacement of the glass fibers of the glass fiber woven cloth by the resin that melts and flows during the heat and pressure molding of the laminate, and as a result, suppress the warpage of the laminate and stabilize the dimensional characteristics. Has an effect on.
