摘要： The present disclosure generally relates to carbon fiber reinforced polyolefin compositions, which may have a relatively low density. The compositions may include a thermoplastic olefin, a filler component, a compatibilizer, and/or an additive package. In some embodiments, the filler component includes a plurality of carbon fibers. In addition, articles of manufacture and methods of making a carbon fiber reinforced polyolefin composition are provided.

摘要： Low density polyolefin compositions with improved stiffness, impact balance, and high dimensional stability are described. These compositions are useful for making automotive components, such as injection molded parts, as well as other articles of manufacture. The compositions comprise (a) a polyolefin comprising polypropylene, a propylene-ethylene block copolymer, or combinations thereof, wherein the polyolefin blend is present in an amount ranging from about 55 wt.% to about 72 wt.%; (b) a first elastomer and a second elastomer that are not the same, wherein the combined weight percent of components (b) ranges from about 18 wt.% to about 33 wt.%; (c) a filler present in an amount ranging from about 6 wt.% to about 12 wt.%: and (d) an additive package present in an amount ranging from about 0.5 wt.% to about 5 wt.%, all wt. % are based on the total weight of the composition.
