Abstract
A thermoplastic composition includes: from about 29 wt % to about 49 wt % of a thermoplastic polymer component including a first thermoplastic polymer consisting of polybutylene terephthalate and a second thermoplastic polymer consisting of polycarbonate, polyethylene terephthalate, copolymers thereof, or a combination thereof; from about 1 wt % to about 30 wt % of a component comprising a polyester elastomer, an ethylene/alkyl acrylate/glycidyl methacrylate terpolymer compatibilizer, or a combination thereof; and from about 50 wt % to about 70 wt % of a ceramic fiber component including ceramic fibers. The first thermoplastic polymer is present the composition in a ratio of at least 2:1 as compared to the second thermoplastic polymer. Articles including the thermoplastic composition are also described.
