A blow-molded plastic structure has a hollow interior portion formed during a blow-molding process, and includes first and second outer portions that are spaced apart from each other, with the hollow interior portion disposed there between. The structure includes a pattern of structural stiffening features that are integrally formed in the second outer portion. The pattern of structural stiffening features includes a plurality of tripodal depressions disposed in rows and columns and a plurality of convex regions disposed in rows and columns between the plurality of tripodal depressions. Each convex region has a maximum height between the first and second outer portions. Each of the tripodal depressions extends into the hollow interior portion, includes three indentations disposed adjacent the first outer portion, and includes an island spaced away from the first outer portion. The island has three sides, each of which is disposed adjacent one of the three indentations.

Disclosed embodiments relate to trays typically comprising a composite internal structure, a thermoplastic frame typically located about the composite internal structure, and two cover sheets forming the upper and lower tray surfaces. The composite internal structure may be a corrugated composite structure in some embodiments. In other embodiments, the composite internal structure may comprise a series of composite elements (which might act a beams or struts). The cover sheets may comprise thermoplastic material, and in some embodiments, the cover sheets may comprise composite material (for example the same as for the corrugated composite structure). In some exemplary embodiments, the thermoplastic frame and the composite internal structure may have the same thermoplastic material, and they may be joined together to have a plurality of homogeneous connective attachments.

A folding table and a manufacturing method of the folding table. The folding table includes a tabletop and a support bracket, the tabletop includes a flat plate and a vertical plate arranged below the peripheral edge of the flat plate. The upper part of the vertical plate protrudes towards the peripheral side of the flat plate to form the clamping part which is clamped with the support bracket. The manufacturing method includes producing a hollow part through a blow molding process, the middle portion of the part concaves inwards; cutting the concave inward part to form two tabletops; and clasping the tabletop on the support bracket.

Disclosed is an edge wrapping method for a composite board, the top board of the composite board surrounds the bottom board of the composite board, a part or all of the side of the top board is disposed with a connecting portion extending beyond the bottom board and extending outwardly; the adjacent portion of the connecting portion and the bottom board are heated, and then the connecting portion is folded toward the inner side of the composite board and the connecting portion is welded to the side of the bottom board. The connecting portion and the bottom board are heated, and the root portion of the connecting portion near one end of the bottom board and the position of the bottom board close to the connecting portion are heated to a molten state, and then, the connecting portion is folded, and the connecting portion and the bottom board are welded together, the production efficiency of the present invention is high, the automatic production is realized, and the product qualification rate is effectively improved.

A plastic molded lip structure may extend along a perimeter of a planar element and may include an outer wall, an inner wall, structural portions, and protruded features. The outer wall may extend in a normal direction from the planar element. The inner wall may be disposed in an inward direction relative to the outer wall. The structural portions may be disposed along structural sections of the perimeter and may include first portions of the inner wall and of the outer wall. The first portions may be disposed parallel to the inner wall and separated from the first portions by a first distance along the structural sections. The protruded features may be interposed between two structural portions and an inner wall may be separated from second portions of the outer wall by a second distance that is greater than the first distance.

The invention relates to a fiber composite component (17) and to a method for producing a fiber composite component (17), for an aircraft, in particular for an aircraft cabin interior, a tabletop (21) or the like, the fiber composite component (17) being formed from a matrix composite material (19) and a support structure, wherein the matrix composite material (19) is formed from cut fibers, a curable resin, and a flame retardant, the support structure being formed from a dimensionally stable fiber composite (18) and/or a metal profile, the matrix composite material (19) together with the support structure being introduced into a component mold and cured to form the fiber composite component (17), the support structure being at least partially bonded with the matrix composite material (19).

A method for manufacturing a part for an aircraft seat includes positioning a heating frame around a stacked structure, locally heating an edge of the stacked structure using a heating frame, externally heating the entire stacked structure, positioning the stacked structure inside a thermoforming mould provided with cutting punches, closing the thermoforming mould and applying a vacuum to the interior of the thermoforming mould, to simultaneously perform, during the same step of shaping the first cover and the second cover, a step of heat sealing an edge of the first cover to an edge of the second cover, bonding the first cover and the second cover to the foam core, and cutting the stacked structure along the circumference thereof using cutting punches.

Filament winding or another technique can be used to create composite parts having various layers of pigmented fibers. The composite parts can then be milled to form one or more flat surfaces on the composite part. Due to the layering of pigmented fibers, the flat surfaces can have a pattern that resembles wood grain or another pattern. These milled composite parts can then be used as components for furniture or other items.
