Abstract
This pultrusion material that is a composite material member comprises: a plurality of fiber sheets that extend along a lengthwise direction; and a gap material that is provided to a gap formed by the plurality of fiber sheets, wherein the gap material has a gap fiber sheet including reinforcement fibers that are oriented in a different fiber direction than the lengthwise direction, and has gap reinforcement fibers that are oriented in the same fiber direction as the lengthwise direction. Additionally, the gap reinforcement fibers are provided evenly distributed in a cross-section of the gap material, said cross-section being perpendicular to the lengthwise direction.
