11173687 · 2021-11-16 · ·

A reinforced substrate is provided for use in molding a composite material. The reinforced substrate has a reinforcing layer having reinforcing fibers extending in a fiber direction that is aligned in a single direction and auxiliary fibers laminated on only one surface of the reinforcing layer so as to extend in only one direction that intersects with the fiber direction. The auxiliary fibers are joined to the reinforcing fibers to hold the reinforcing layer. The auxiliary fibers have a higher tensile elongation at break than do the reinforcing fibers. The reinforcing layer is arranged with fiber bundles of large tows being aligned in an unopened state. The large tows have a higher fiber count of the reinforcing fibers than does a regular tow.
