摘要:
The invention relates to a rod-shaped fiber composite material (400) composed of a matrix (412) and a circular braid (402) embedded into the matrix. To increase the stability of the fiber composite material (400) and also to perform ducting functions for electricity and fluids, the wall of the circular braid is provided with wall chambers (408) which are separated by a phase boundary from the matrix (412) of the fiber composite material (400). These wall chambers (408) lead to inner and outer sections of the wall of the circular braid (402) being spaced apart, which is useful for the stability with regard to flexing and torsional loading in particular. Rod-shaped fiber composite materials (400) according to the invention can be used for creating stable structural components as well as for producing efficiently protected ducts. The invention further relates to an apparatus and a process which are useful for producing fiber composite material according to the invention.

摘要:
Method and arrangement for manufacturing core composite layer workpieces (sandwich structures) from at least one first and at least one second cover sheet (1, 2) between which a core sheet (30) including especially short cut fibers (9) is provided, are disclosed with which a continuous and substantially break free manufacture can be conducted which leads to composite layer structures with reasonable costs. Single manufacturing parameters can specifically be varied with different embodiments so that in a relatively simple manner composite layer structures with desired physical properties can be obtained, for example with respect to their strength, stiffness, flexibility, mechanical and acoustic absorption capabilities, working properties, and so on. Composite layer structures for new applications can be manufactured as well.

摘要:
A valve device for a gaseous medium of an airbag is provided. The valve device includes a textile layer, in particular a woven fabric, which is permeable with respect to the medium at least in certain regions. The valve device also includes at least one film covering the textile layer in at least one region and which forms at least one passage region of the valve device, which is at least substantially closed in a closed position of the valve device and open at least in certain regions in an at least temporary passage position of the valve device.
