Prepreg and method for producing prepreg

Abstract

The present invention is a prepreg containing a resin composition and a carbon nanotube film. The resin composition is impregnated in the carbon nanotube film. The resin composition contains a free radical polymerizable thermosetting oligomer and a polymerization initiator. The aromatic nucleus concentration of the resin composition is 0.1 mol / kg or more. The weight per unit area of ​​the carbon nanotube film is 0.0226~170 mg / cm2. The carbon nanotube film is a carbon nanotube network stack. A prepreg containing a resin composition and a carbon nanotube film, wherein the carbon nanotube film is impregnated with the resin composition, the resin composition contains a radical polymerizable thermosetting oligomer and a polymerization initiator, the resin composition has an aromatic nucleus concentration of 0.1 mol / kg or greater, the grammage of the carbon nanotube film is within a range from 0.0226 to 170 mg / cm2, and the carbon nanotube film is a carbon nanotube web laminate.
