Abstract: A vehicle interior trim system such as an instrument panel or a door panel includes a panel substrate defining a deployment aperture. An inflatable device such as an air bag is adapted to deploy through the aperture during a crash. A natural, tanned leather skin covers the substrate, wherein the skin has a tear seam corresponding to the aperture on a hidden surface of the skin. An aperture door may be fitted within the deployment aperture which is adapted to open against the skin in response to deployment of the inflatable device. The tear seam is comprised of a region on the hidden surface of the skin having a disrupted fiber matrix from exposure to an alkaline solution such as ammonia, bleach, sodium tetraborate, sodium hydroxide, sodium bicarbonate, trisodium phosphate, potassium hydroxide, and potassium carbonate.

Abstract: The present invention is directed toward providing a headliner for a motor vehicle comprising an interior layer adapted to present a surface that is exposed to the interior of the vehicle, a flexible film assembly that is supported by the interior layer opposite to the interior of the vehicle; and a fill layer adapted to be flowed over the flexible film and subsequently hardened to form a main supporting body of the headliner. The flexible film assembly has a first film layer adapted to establish a generally flat base surface that is mounted to the interior layer and a second film layer supported on the first film layer having a plurality of voids formed by portions of the second film layer that are spaced from said first film layer at predetermined intervals so as to establish an undulating upper surface of the film assembly. The plurality of voids are adapted to act as a plurality of resonating cavities to attenuate acoustical frequencies within the vehicle.

Abstract: A method of producing composite vehicle door panels. A skin is manufactured in a vacuum-forming mold. The skin is then transferred to a RIM mold. Next, natural fibers and an isocyanate and a resin mixture are placed on the skin. The isocyanate and resin mixture, the natural fiber, and the skin are then polymerized into a composite panel.

Abstract: This process and apparatus use at least one chopper unit. The fiber choppers may be laser beam choppers or existing standard chopper units. The process and apparatus for producing a fiber-reinforced molded composite comprises providing a moldable composition, sequentially spraying a moldable composition into the mold, subsequently providing chopped fibers to the moldable composition and depositing the moldable composition and chopped fibers in mold and molding the moldable composition and fibers in the apparatus under heat and pressure to form the molded composite. One industrial application for these choppers is compression molding of interior trim panels for automobile doors. The choppers spray chopped glass fiber strands into a resin mixture. The glass and a polyol, isocyanate (—NCO) urethane resin mixture at the proper glass loading, distribution and pattern is fed to the mold.

Abstract: This process and apparatus use at least two chopper units. The fiber choppers may be laser beam choppers or existing standard chopper units. The process and apparatus for producing a fiber-reinforced molded composite comprises providing a moldable composition, a first fiber chopper providing chopped fibers to the apparatus from a first direction, a second fiber chopper providing chopped fibers to the apparatus from a second direction, wherein the first direction is different from the second direction and molding the moldable composition and fibers in the apparatus under heat and pressure to form the molded composite. One industrial application for these choppers is compression molding of interior trim panels for automobile doors. The choppers spray chopped glass fiber strands into a resin mixture. The glass and a polyol, isocyanate (—NCO) urethane resin mixture at the proper glass loading, distribution and pattern is fed to the mold.

Abstract: This apparatus uses a programmable controller to control laser beam and standard fiber chopper units. The units usually are affixed to resin mix heads. The conventional choppers use steel blades that are randomly spaced, angled and sized. The PC also varies the speed of the standard chopper. The laser device operates in a manner that allows one to set the pulse rate for the specific purpose of varying the fiber length. During operation, the intensity of the laser may be adjusted to accommodate cutting or different sizes and kinds of fibers. The apparatus preferably produces fiber reinforced urethane substrates such as interior door panels for automobile doors.

Abstract: This apparatus uses laser beams in place of existing standard glass chopper units affixed to resin mix heads. Conventional glass choppers use steel blades that eventually wear out or break, adding to maintenance costs. The laser device operates in a manner that allows one to set the pulse rate for the specific purpose of varying the fiber length. During the injection operation, intensity of the laser may be adjusted to accommodate cutting or different sizes and kinds of fibers. The laser apparatus preferably produces long fiber reinforced urethane substrates such as interior door panels for automobile doors.
