Abstract

PURPOSE: The cellulose base material holding a resin solution of, e.g. an epoxy resin is treated with heat and moisture, thus permitting the use of high-concentration resin solution, reducing the troubles such as tearing, facilitating the deposition of exhaust gas and producing prepregs in low costs.
CONSTITUTION: The cellulose base material 1 such as cotton linter paper is passed through the resin tank 11 mainly containing phenolic resin or epoxy resin to prepare the resin-holding base material 2. The base material 2 is sent through the squeeze rollers 12 and to the chamber where it is treated with heat and moisture that is higher in hymidity than that is obtained when the ambient air is heated to the treating temperature, preferably higher than 50°C. Then, the resultant base material 2 is sent to the drier 16 where it is dried with hot air to produce the objective prepreg.
USE: Production of laminates.
