Since this method of impregnating a base material with resin varnish is characterized by impregnating it with resin varnish as follows, it is possible to impregnate the resin varnish without narrowing the intersection of the warp and weft of the glass cloth and the space between the filaments. This makes it possible to obtain a resin-impregnated base material with no residual air within the base material.The present invention will be described in detail below.

。The long strip-shaped base material used in the present invention has a thickness of 0.05 to 1.0 mm and a width of about 1 m to about 2 m, and is made of inorganic fibers such as glass, asbestos, polyester, polyamide, polyaramid, polyvinyl alcohol, polyacrylic, etc. The base materials include woven fabrics, non-woven fabrics, woven fabrics, paper, or combinations thereof made of organic synthetic fibers and natural fibers such as cotton. Resin varnishes include phenolic resin, cresol resin, epoxy resin, non-9ated polyester resin, melamine resin, polyimide, polybutadiene, polyamide, polyamide-imide, polysulfone, polyphenylene sulfide, polyphenylene oxide, polybutylene tele-7-thalerate polyether ether ketone. , fluorinated resins, etc. alone, modified products, mixtures, etc. are used, and if necessary, water, methyl alcohol,

g medium'fr added. The tension of the long strip base material needs to be 10 KQ/c4 or less to impregnate it with the resin varnish. That is, if +OKq/d is exceeded, the space between the glass cloth intersection point and the filament cannot be sufficiently expanded, and therefore only a resin-impregnated base material with residual air inside the base material can be obtained. The tension of the long strip base material can be set to +nKq/d or less by adjusting the speed difference between the feed roll and the take-up feed roll before and after impregnation, but this is not particularly limited. Impregnation means
Even if you get stuck, you can use dipping, spray coating, transfer, casting, etc., and there are no particular limitations, and it is also possible to perform initial impregnation, such as primary, secondary, and tertiary impregnation. be.

I Fully immersed the feed roll into an impregnating tank containing epoxy varnish (diameter) and dried the resin for 4 seconds.
After impregnation to a weight of 4, the taken-up feed roll was dried in a dryer with a diameter to obtain a resin-impregnated base material, but the speed ratio of the taken-up feed roll was set to 1 at the start of operation. The feed roll was set at 1.2, and after steady operation, the speed of the feed roll and the take-up feed roll were synchronized and the tension of the long strip base material at this time was 5KQΔ.
