Such compositions and methods may be used to form articles including, but not limited to, automotive bezels and housings in consumer devices.

A reinforced resin composition may include a polycarbonate, a functionalizing agent, and an inorganic filler that has been functionalized with the functionalizing agent, the functionalized inorganic filler being present in an amount ranging from 1 to 25 percent by weight of the resin composition. The reinforced resin may exhibit a melt flow index of 25 or less, when measured at a load of 1.2 kg, after allowing the resin to remain at a temperature of 300 C. for 10 minutes. A method of reducing thermal degradation of a reinforced polycarbonate material may include introducing into said polycarbonate material at least one inorganic filler functionalized with a functionalizing agent, such that the reinforced resin exhibits a melt flow index of 25 or less, when measured at a load of 1.2 kg, after allowing the resin to remain at a temperature of 300 C. for 10 minutes.
