Abstract: A method produces a flat semi-finished product from a fiber composite material that contains individual carbon fibers, carbon fiber bundles, or a mixture thereof in a defined anisotropic fiber orientation and a thermoplastic matrix material. The anisotropy of the carbon fibers is created in a carding process using the high orientability of admixed non-carbon textile fibers, at least some of the non-carbon textile fibers being thermoplastic, and the carbon fibers having been isolated from waste or used parts. The flat fibrous web which is produced by a carding process and which has a specific orientation of the carbon fibers in the longitudinal direction is compressed into a sheet material under the effect of heat. This enables the use of carbon fibers, for example from production waste, as reinforcing fibers, whereby a less expensive raw material is provided and the carbon fibers are contained in the waste materials are recycled.

Abstract: Polymer articles are often reinforced by addition of fibers which may be assembled into a structured reinforcement such as a woven mat or sheet and the mat or sheet serves as the reinforcement. Such woven fiber-reinforced polymer composite articles may exhibit undesirable variations in surface height which mimic the geometry of the underlying reinforcements, a phenomenon known as print through. By forming, on the surface of the article, a relatively thin, layer of a compatible polymer incorporating closely-spaced, short, carbon nanotubes more or less uniformly dispersed throughout the layer and oriented normal to the article surface, print through may be reduced or eliminated. Methods for fabricating such an article are detailed.

Abstract: Pile weatherstripping is provided by a flat pile of strands which are tensioned to spring outwardly to straight condition to provide a pile weatherstrip, when bent and inserted into a T-slot or other kerf in a member such as a window or door frame or sash. The tendency of the bent parts of the pile to spring away from each other facilitates retention of the pile after insertion into the slot. A locking fin, more rigid than the pile, is preferably used. This locking fin engages steps or edges in the throat of the slot thereby impeding withdrawal of the weatherstripping from the slot. One or more barrier fins may also be assembled with the strands constituting the flat pile. The pile can be operated in bending mode or in columnar compression (crushing mode). Bending mode operation can be over a bending range so as to accommodate a large range of clearance between a sash and a frame or other members which are sealed by the pile weatherstripping.
