Abstract:
A method of forming high strength panels suitable for use in applications requiring a capability to withstand point compression loading without deformation, comprising the steps of:positioning a first fabric layer spaced from a second fabric layer to form opposing panel surfaces; fixing a foam core between at least a portion of said fabric layers to form said panel; defining in at least one of said opposing panel surfaces an elongated channel having a cross-sectional profile; forming a rigid point compressive load bearing member having a structural foam core, an outer fabric layer including fabric flaps and said cross-sectional profile of said elongated channel; applying resin to said flaps and mating surfaces of the rigid point oppressive load bearing member and said elongated channel; positioning said rigid point compressive load bearing member in said elongated channel after said applying step; and allowing said resin to cure to provide along a length of said rigid point compressive load bearing member a greater resistance to point compression as compared to a remaining portion of said panel exclusive of said rigid point compressive load bearing member.
