US Patent 10563398 Method of stiffening a frame supported panel

A method of stiffening a frame supported panel by inducing a new condition on the panel is disclosed. When a fixed/continuous/dropped condition is induced on a continuous panel by bonding polyurethane to the panel's backside and to the sides of supporting frame members, the panel's load capacity can be greatly increased, with the lower the panel's flexural stiffness, the greater the increase in load capacity. This enables weaker, lighter, thinner and less costly panels to to become stiffer, stronger and more versatile.
