A filled hollow structure includes an open hollow structure from a first material. The open hollow structure is at least partially closed by a closing structure. The hollow structure is filled with a filler medium. The filled hollow structure is overmoulded with a second material.

A fiber composite material component has fiber bundles and a matrix of thermoplastic and/or thermosetting material. The fiber bundles are arranged such that they form a profile. Bracing structures are arranged between the fiber bundles. At least two fiber bundles are arranged in a skewed manner with respect to one another and at least one cavity is formed in the region of the intersection of the skewed fiber bundles. Furthermore, a method for producing a fiber composite material component having fiber bundles and a matrix of thermoplastic and/or thermosetting material, is provided.

A composite component assembly may include a composite core including a plurality of core cells between first and second ends. A connection joint is formed between the first and second ends. An adhesive layer is disposed within the connection joint between the first and second ends. The adhesive layer is configured to bond the first and second ends through a curing process. A peg splice securing joint securely connects the first and second ends together before and during the curing process.

The invention relates to a device and a method for the thermal reshaping of hose blanks from preferably pre-extruded elastic raw hose material, wherein during the reshaping the hose blank is arranged in a shell-like, single- or multi-piece molding tool with a hollow body, wherein the inner side of the hollow body corresponds as a negative to the shape to be impressed onto the hose blank, wherein the tempering of the molding tool that is necessary for reshaping occurs by means of clamp-like tempering elements which are shaped congruently to the outer surface of the mold and which close form-fittingly over the mold, while the molding tool itself does not comprise any tempering system at all, in particular no ducts or other hollow spaces for circulating a tempering medium, and wherein the temperature of each tempering element is kept constant during the process, while, to modify the temperature of the molding tool, a different tempering element with a correspondingly constant temperature is positioned against the molding tool; in the claimed device, the molding tool is free of internal ducts and other hollow spaces for the circulation of a tempering medium, while half or partial shells, which are separate from the mold and which close form-fittingly over the mold, are provided to temper the molding tool, wherein the inner sides of said shells which face the molding tool are congruent with the outer side of said molding tool and wherein the shells comprise an arrangement for keeping the temperature of each tempering element constant during the process, in particular internal hollow spaces for the perfusion of a tempering medium, and wherein at least one mechanism is provided for selectively closing different tempering elements at different temperatures around the molding tool.

A double-layer cushioning structure and a preparation process thereof, relating to technical field of packaging products. It includes a buffer cover. Hollow double-wall structure in buffer cover play a good buffer role, when an outer wall is deformed inwards by impact of external force, reactive force will offset impact of external force to achieve buffer effect; first reinforcing ribs and second reinforcing ribs strengthens strength of inner and outer walls, thereby reducing wall thickness, softening product, and saving processing materials; first connecting holes, second connecting holes, and support holes between inner and outer walls can better support inner and outer walls, and longitudinally strengthen buffer cover, and further ensure overall structural strength of buffer cover; soft material is provided on a wall surface of a product protection groove, to further soften wall surface in contact with the product to protect surface of product from being scratched.

The invention relates to a method for producing a fiber-reinforced, polymeric continuous profiled element (1), wherein the continuous profiled element (1), having preferably at least one hollow chamber (2, 2), comprises a core profile (10) which can be produced by means of a pultrusion process, and wherein during the pultrusion process at least one continuous strand having reinforcement fibers (5) is integrated into the polymer matrix (4) of the core profile (10). According to the invention, the curing of the core profile (10) is carried out by means of a dual-cure method.
