Recycling trim components |
摘要 |
The invention relates to a method for the recycling of trim components of vehicles. The method comprises the steps of shredding manufacturing scrap and post-consumer scrap from vehicle headliners into small particles to produce fluff. This fluff is then combined with water and a binder reagent composed of either polyisocyanates, or polyisocyanates combined with various polyols. The solution of fluff, binder reagent and water are mixed, and then placed in a mold where the mixture is formed into a pre-preg sheet. Subsequently, the pre-preg sheet is subjected to compression molding at elevated temperatures to produce a finished composite trim panel. As part of the final compression molding step, a decorative coverstock can be included to produce a finished trim panel having a decorative cover.
