摘要
Provided are a tow prepreg comprising a reinforcing fiber bundle impregnated with a matrix resin composition, wherein the matrix resin composition contains a component (A) (an epoxy resin), a component (B) (dicyandiamide), a component (C) (a curing accelerator), and a component (D) (a core-shell type rubber particle), and a content of the component (D) with respect to 100 parts by mass of the component (A) is from 20 to 70 parts by mass, a viscosity is from 3 Pa·s to 80 Pa·s at 30°C, and a minimum viscosity to be obtained when a viscosity is measured by raising a temperature from room temperature to 130°C at a rate of temperature rise of 2.0°C/min is from 0.04 Pa·s to 1 Pa·s, which exhibits excellent drape property and tackiness and less stickiness and can be unwound at a high speed; and a composite material-reinforced pressure vessel having fewer voids in a reinforcing layer which is obtainable by using the tow prepreg, a high burst pressure, and an excellent appearance due to appropriate resin flow.
