The plurality of pieces of low density cellular material, such as foam plastics, form a core panel having opposite side surfaces and with adjacent pieces having opposing edge surfaces extending between the side surfaces. Sheets of flexible material, such as veils or mats or scrim, are adhesively attached to the side surfaces, and portions of one sheet extend between the opposing adjacent edge surfaces for limiting flexing of the panel. The pieces may be tapered, and portions of the one sheet may project between the edge surfaces either partially or fully to form double wall webs. The webs may have flanges adhesively attached to the other sheet on the opposite side. One sheet may also be stretchable in areas not adhesively attached to the pieces to provide for curving the panel from a planar position maintained by the sheet on the opposite side.

Composite cores and panels

A modular structure formed by panels is disclosed, having a center compartment and first and second side compartments coupled to the opposing sides of the center compartment. Each panel of the modular structure is joined to each respective adjacent panel via a panel joining assembly to substantially prevent moisture from entering the modular structure. An upper roof panel coupled to the center compartment is joined to first and second lower roof panels coupled to the first side compartment and the second side compartment, respectively, via first structural joining assemblies so that the upper roof panel is elevated relative to the first and second lower roof panels to substantially prevent moisture from entering the modular structure.

Rapid assembly of a modular structure

A composite core panel is produced by arranging a plurality of foam strips in adjacent relation and advancing the strips with one or two flexible sheets of porous reinforcement material and adhesive between platens to form a panel. The sheet on one side of the strips is folded between adjacent strips to form double wall pleats which may project either partially or fully between the strips and may have folded end portions overlying the other side of the strips. The second sheet may also form double wall pleats between the strips and be connected to the pleats in the first sheet. The core panel may be cut to form reinforced strips which are connected by adhesive in various arrangements to form other core panels. A core panel may also be formed by wrapping each foam strip longitudinally with a strip of reinforcing material and connecting the strips with adhesive.

Composite reinforced cores and panels

A fiber reinforced core panel is formed from strips of plastics foam helically wound with layers of rovings to form webs which may extend in a wave pattern or may intersect transverse webs. Hollow tubes may replace foam strips. Axial rovings cooperate with overlying helically wound rovings to form a beam or a column. Wound roving patterns may vary along strips for structural efficiency. Wound strips may alternate with spaced strips, and spacers between the strips enhance web buckling strength. Continuously wound rovings between spaced strips permit folding to form panels with reinforced edges. Continuously wound strips are helically wrapped to form annular structures, and composite panels may combine both thermoset and thermoplastic resins. Continuously wound strips or strip sections may be continuously fed either longitudinally or laterally into molding apparatus which may receive skin materials to form reinforced composite panels.
