Abstract
According to the present invention, a gas tank having a gas-barrier inner shell and an outer shell that is formed so as to cover the inner shell and is made of a pressure-resistant FRP, such outer shell comprising reinforcing fiber bundles (A), a thermosetting resin (B), and an elastomer particles and/or thermoplastic resin particles (C), provided that elastomer particles and/or thermoplastic resin particles (C) that have been dispersed in a thermosetting resin (B) exist in reinforcing fiber bundles (A), is provided. Such gas tank is excellent in strength and heat resistance and has suppressed gas permeability.
