Abstract
PURPOSE: A prepreg sheet having good storage stability, prepared by applying cured layers consisting of photocurable resin composition containing a curing agent to both sides of a layer consisting of a curing agent-free thermosetting resin composition infiltrated into a substrate.
CONSTITUTION: A prepreg sheet is prepared by impregnation of a substrate 3 (e.g., paper, nonwoven fabric, etc.) with a curing agent-free thermosetting resin (e.g., bisphenol A-derived epoxy resin), followed by drying to form a layer 4 of the thermosetting resin composition, coating both sides of the layer with a photocurable resin (e.g., unsaturated polyester resin) containing a photopolymerization initiator (e.g., benzophenone) and a curing agent for the above thermosetting resin (e.g., boron trifluoride-monoethylamine) and curing the coatings by ultraviolet ray irradiation to form layers 5 consisting of the curing agent-containing photocurable resin composition.
