Abstract

A panel is disclosed. The panel includes a core layer; one or more first reinforcement layers connected to the core layer and one or more second reinforcement layers connected to the one or more first reinforcement layers. The one or more first reinforcement layers includes randomly chopped fibers that impart stiffness to the panel in all directions (X, Y, Z). The one or more second reinforcement layers includes first directional fibers that impart stiffness to the panel in only one direction (X). Another panel is also disclosed. The panel includes a core layer; one or more first reinforcement layers connected to the core layer and one or more second reinforcement layers connected to the one or more first reinforcement layers. The one or more first reinforcement layers includes randomly chopped fibers that impart stiffness to the panel in all directions (X, Y, Z). The one or more second reinforcement layers includes a woven material including first directional fibers that are woven into second directional fibers. The first directional fibers impart stiffness to the panel in only a first direction (X). The second directional fibers impart stiffness to the panel in only a second direction that is substantially perpendicular to the first direction.
