Abstract
The present invention provides a method for producing a surface-treated glass fiber film comprising steps of: preparing a treatment solution consisting of a mixture of a hydrolysable silane compound and a partially hydrolyzed condensate thereof; coating a glass fiber film with the treatment solution so that the attached amount of the mixture is 2% by mass or more and 90% by mass or less, relative to 100% by mass of the surface-treated glass fiber film and drying the same; and heat-treating the glass fiber film coated. There can be provided a method for producing a surface-treated glass fiber film having high strength, a low average coefficient of linear expansion, a high storage rigidity at high temperature and excellent in heat resistance, flexibility, electric insulation, dimensional stability, and surface homogeneity, with less environmental impact.
