Prepreg and molded article |
| abstract |
Provided is a prepreg containing a urethane-modified epoxy (meth)acrylate (A) that is a reaction product of an epoxy (meth)acrylate (a1) having an average of 1.8 to 2.6 hydroxy groups and a polyisocyanate (a2) having an average of 2 to 3 isocyanate groups, an ethylenically unsaturated monomer (B), a polymerization initiator (C), and reinforcing fibers (D) as essential components, in which the molar ratio (NCO/OH) of isocyanate groups (NCO) in the polyisocyanate (a2) to hydroxy groups in the epoxy (meth)acrylate (a1) is 0.6 to 1.1, and the proportion of the ethylenically unsaturated monomer (B) in the total mass of the epoxy (meth)acrylate (a1) and the ethylenically unsaturated monomer (B) is 10% to 50% by mass. The prepreg has good workability and good moldability and can be appropriately used for various molded articles such as automotive members because various excellent physical properties such as interlaminar shear strength and heat resistance are provided. |
