COMPOSITE MATERIAL MEMBER, GAP MATERIAL, PULTRUSION DEVICE, AND PULTRUSION METHOD

摘要

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 22 that is provided to a gap formed by the plurality of fiber sheets, wherein the gap material 22 has a gap fiber sheet 26 including reinforcement fibers that are oriented in a different fiber direction than the lengthwise direction, and has gap reinforcement fibers 24 that are oriented in the same fiber direction as the lengthwise direction. Additionally, the gap reinforcement fibers 24 are provided evenly distributed in a cross-section of the gap material 22, said cross-section being perpendicular to the lengthwise direction.
