Fiber structure and fiber-reinforced composite material

Abstract

A fiber structure serves as a reinforcement of a fiber-reinforced composite material that includes matrix resin as a matrix. The fiber structure includes a plurality of first reinforcing fiber yarns and a second reinforcing fiber yarn. The first reinforcing fiber yarns is each formed of a bundle of fibers including discontinuous fibers made of reinforcing fibers. The bundle of fibers is wrapped with a covering yarn. The second reinforcing fiber yarn is formed of a bunch of continuous fibers made of reinforcing fibers. The fiber structure includes a fiber body formed of the first reinforcing fiber yarns and the second reinforcing fiber yarn arranged alongside and extending in the same direction. The fiber body has a portion in which the second reinforcing fiber yarn is held between and by the first reinforcing fiber yarns.
