Abstract: Composite articles that can resist discoloration or color changes are described. In some instances, the composite articles can include a compounded material that is substantially free of an antioxidant that changes from a first color to a second color upon exposure to an environment comprising an oxidizing agent. The composite articles can be flame retardant and may provide sound reduction as well.

Abstract: Certain embodiments described herein are directed to articles that provide less sag. In some examples, the articles can include a fiber reinforced thermoplastic polymer core layer comprising reinforcing fibers and a thermoplastic polymer, and a frim disposed on the fiber reinforced polymer core layer. In certain examples, the frim comprises a film coupled to a scrim comprising an effective basis weight to prevent substantial sag of the article, e.g., during a forming operation.

Abstract: Thermoplastic composite articles are described that comprise reproduced polymeric fibers in one or more of a core layer and a skin layer. In certain arrangements, the thermoplastic composite article can include a porous core layer comprising a web of open celled structures comprising random crossing over of a plurality of reinforcing fibers and a plurality of reproduced polymeric fibers held together by a thermoplastic material, and a skin layer disposed on a first surface of the porous core layer. The thermoplastic material can include virgin and recycled thermoplastic materials if desired. Exterior and interior components produced using the thermoplastic composite articles are also described.

In certain arrangements, the thermoplastic composite article can include a porous core layer comprising a web of open celled structures comprising random crossing over of a plurality of reinforcing fibers held together by a thermoplastic material. The thermoplastic material can include virgin and recycled thermoplastic materials if desired. The web may also comprise biomaterials that can be bioparticles, biofibers or both. Exterior and interior components including the thermoplastic composite articles are also described.

Abstract: Consolidated, porous core layers that are lightweight while retaining the mechanical properties of heavier core layers are described. The consolidated, porous core layer can include a porous web formed from reinforcing materials held in place by a thermoplastic material. The consolidated, porous core layer can also include a lofting agent or other additives to provide for a desired thickness or properties.

Abstract: Methods of forming a lightweight reinforced thermoplastic core layer and articles including the core layer are described. In some examples, the methods use a combination of thermoplastic material, reinforcing fibers and bicomponent fibers to enhance retention of lofting agents in the core layer. The processes permit the use of less material while still providing sufficient lofting capacity in the final formed core layer.

Abstract: In-line systems and in-line methods of producing lightweight reinforcing thermoplastic composite panels are described. The in-line systems and in-line method can be used to produce composite panels with smoother surfaces and enhanced properties in an automated manner. The produced composite panels can include a decorative layer that can provide an overall smoother panel surface compared to a composite panel lacking a decorative layer.

Abstract: Methods and systems that can produce light weight reinforced thermoplastic articles are described. In some embodiments, a method includes heating and pressing a core layer and then cooling and pressing the core layer to maintain the thickness of the core layer during cooling. Automotive articles, building articles and recreational vehicle articles that can be produced using the methods and systems are also described.
