<p>PROBLEM TO BE SOLVED: To provide a method for manufacturing a prepreg of a filament-reinforced resin material with improved mechanical strength such as elastic modulus, tensile strength and impact strength, and further, improved productivity and cost.SOLUTION: A method for manufacturing a prepreg includes: a step A of causing glass cloth to contact with a liquid-type modified polypropylene resin; a step B of impregnating the liquid-type modified polypropylene resin into the glass cloth; and a step C of solidifying the impregnated modified polypropylene resin. The modified polypropylene resin is obtained by reacting a polypropylene resin and an alkylphenol resin under a presence of a radical initiator.</p> |
