Abstract
It is an object of the present invention to provide a resin composition for FRP, an FRP sheet and a molded product that enable inhibition of the whitening in and between fiber bundles. A resin composition for FRP according to an embodiment of the present invention is a resin composition with which a fibrous reinforcement sheet is to be impregnated for formation of FRP, and contains methyl methacrylate as a principal component, a methyl methacrylate polymer, a polymerization initiator, and at least one of dendrimer (meth)acrylate and glycidyl (meth)acrylate, as a monomer. An FRP sheet according to another embodiment of the present invention includes a matrix and a fibrous reinforcement sheet in the matrix. The matrix contains the hardened resin composition for FRP.
