摘要:
The invention relates to a motor vehicle part material structure for sound insulation for the motor vehicle interior and motor vehicle trunk, namely floor mats, floor coverings, and trunk linings, that makes it possible to industrially implement complete reprocessing of the entire composite, in particular the fiber material. The motor vehicle part has a PET fiber layer, an optional substrate layer made of PET and/or COPET, an optional PET adhesive layer, a PET adhesive layer, a layer made of PET fiber nonwoven fabric or woven fabric, and an insulating layer made of PET/COPET.

The invention relates to a 3-dimensional high-strength fiber composite component having isotropic fiber distribution, comprising 25 to 70 wt% of high-strength, high-modulus fibers, up to 5 wt% of binding fibers, and 25 to 70 wt% of thermosetting or thermoplastic matrix. The invention further relates to a method for producing same, comprising the following steps: preparing (1, 2, 3) the fibers by opening the fibers by releasing the fibers from fiber bundles, bales, or textile structures; sucking and/or blowing (6) the opened fibers onto a three-dimensional, air-permeable tool half (5) having the contour of this side of the component in an interactively controlled manner; pre-solidifying the obtained fiber molding in the flock box (4); transferring the fiber molding (7) onto a pressing tool (11) in the form of the contour of the air-permeable tool half (5) of the component; bringing (10) into contact with at least one liquid plastic; and solidifying the fiber molding by pressing (11) in order to form a component.
