PROBLEM TO BE SOLVED: To solve the problems with: deterioration in basis weights in both side end parts of a reinforced fiber sheet, occurring when a unidirectional prepreg is manufactured by a hot melt method; deterioration in handleability of the unidirectional prepreg resulting from excessive adhesion of an overflowed matrix resin to both side end parts of the unidirectional prepreg when a resin is impregnated; and reduction in strength of the unidirectional prepreg when used as a fiber reinforced composite material.SOLUTION: The method for manufacturing a unidirectional prepreg comprises a matrix resin adhesion process, a sealant arrangement process, a matrix resin impregnation process and a sealant removal process. |
