Abstract: A cross-car beam, includes a plastic beam body 22, defining a first end 24 and a second end 26 spaced from the first end 24 along a first direction D1, such that the plastic beam body 22 is elongate in the first direction D1. The plastic beam body 22 further defines a cross-sectional shape 28 along, a plane P1 that is normal to the first direction D1. The cross-car beam 20, may further include a metallic beam body 42 configured to be coupled to the plastic beam body 22. The metallic beam body 42 defining a first end 44 and a second end 46 spaced from the first end 44 along a direction, for example the first direction D1 when the metallic bean body 42 is coupled to the plastic beam body 22, such that the metallic beam body 42 is elongate in the first direction D1.

Abstract: A polymer composition includes: about 20 wt % to about 80 wt % of a polycarbonate polymer; about 1 wt % to about 20 wt % of a polycarbonate-siloxane copolymer; about 15 wt % to about 35 wt % of a reinforcing filler having a tensile modulus of at least about 150 GPa; and about 4 wt % to about 20 wt % of a flame retardant comprising phosphorous. The polymer composition demonstrates a flexural modulus in an amount equal to or greater than about 10 GPa. Methods of forming a polymer composition and blended thermoplastic compositions are also described.

Abstract: Internally lubricated polymer compositions containing a styrene- and/or polyphenylene ether-containing polymer, an olefin-containing polymer, and a compatibilizer are provided. The olefin-containing polymer, which is present in the compositions in about 3 to about 30 weight percent, provides internal lubrication and improves the tribological properties of the compositions compared with the styrene- or polyphenylene ether-containing polymer alone, as determined by wear measurements. Preferred compositions exhibit wear factors less than about 130×10?11n mm5/Pa-m. A preferred composition includes a blend of polystyrene/polyphenylene ether, linear low density polyethylene, and styrene-ethylene-butadiene-styrene.
