摘要： 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.

摘要： 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.

摘要： 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.
