By taking into account the difficulty in smoothly bending along the shape of, for example, a care bed, there is provided a three-dimensional net-like structure made from polyethylene having a swelling ratio dependent on a shear rate such as to be 0.93 to 1.16 at a shear rate of 24.3 sec.sup.1 and 1.15 to 1.34 at a shear rate of 608 sec.sup.1 and having an MFR of 3 to 35 g/10 min and a density of 0.82 to 0.95 g/cm.sup.3 and configured to have a spring structure of filaments randomly brought into contact with and tangled with one another, have a three-dimensional striped sparse-dense configuration in a lateral direction relative to an extrusion direction. The swelling ratio is shown as D.sub.2/D.sub.1 against shear rate when a molten thermoplastic resin is extruded to filaments from a capillary having a tube inner diameter D.sub.1 of 1.0 mm and a length of 10 mm and D.sub.2 denotes a diameter of cross section of the filaments extruded and cooled down.

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.

A hoisting device rope has a width larger than a thickness thereof in a transverse direction of the rope. The rope includes a load-bearing part made of a composite material, the composite material including non-metallic reinforcing fibers, which include carbon fiber or glass fiber, in a polymer matrix. An elevator includes a drive sheave, an elevator car and a rope system for moving the elevator car by means of the drive sheave. The rope system includes at least one rope that has a width that is larger than a thickness thereof in a transverse direction of the rope. The rope includes a load-bearing part made of a composite material. The composite material includes reinforcing fibers in a polymer matrix.

A layered composite includes an insulation sheet and at least one scrim layer secured thereto. The at least one scrim layer may be embedded within the thickness of the insulation sheet, or bonded to a corresponding face of the insulation sheet, and have a tensile strength greater than that of the insulation sheet. As such, the scrim layer provides structural support to the insulation sheet as well as a trap for fibers or particles that may separate from the insulation sheet.
