METHOD FOR MANUFACTURING PREPREG AND LAMINATED SHEET

摘要

PROBLEM TO BE SOLVED: To provide a method for efficiently manufacturing a prepreg in which the warpage of a base material can be measured after being dried without lowering manufacturing efficiency and thus enables the efficient manufacturing of the prepreg with reduced warpage, in a continuous prepreg manufacturing process and a method for manufacturing a laminated sheet using the prepreg manufactured by the prepreg manufacturing method. SOLUTION: In the prepreg manufacturing method, a means to transfer the base material used when its warpage is measured during its transfer after a half-curing process is such a means that one of both ends of the base material in parallel with the advancing direction of the transfer means is not held. In addition, either of both the ends which is not held by the transfer means is subjected to the measurement of the warpage of the base material. COPYRIGHT: (C)2006,JPO&NCIPI
