Abstract
In the manufacture of prepreg using various types of resin varnish having different properties, prepreg having good appearance and desired properties is manufactured without decreasing productivity. A prepreg manufacturing apparatus is able to perform, in a base material feeding path, immersing a base material in resin varnish in a tray, scraping off the excess resin varnish on the base material with scraping rollers which are provided above the tray, and thereafter drying the base material with a drying device. The prepreg manufacturing apparatus is configured such that, on the base material feeding path, the distance from the liquid surface of the resin varnish in the tray to the scraping rollers and the distance from the scraping rollers to the drying device are adjustable.
