Abstract: A composition includes a polymer base resin, a fiber filler including a sizing agent component, and an additive. The sizing agent component includes a sizing agent and a reactive aid. The composition exhibits a notched Izod impact strength of 140 to 190 J/m, and an unnotched impact strength of 500 to 1200 J/m when tested in accordance with ASTM D256.

Abstract: A thermoplastic composition includes: (a) a thermoplastic polymer component including a crystalline or semi-crystalline polymer: (b) carbon fiber: (c) from about 0.01 wt % to about 10 wt % of at least one nucleating agent including a non-electrically conducting filler, an organic nucleation agent, or a combination thereof; and (d) from 0 wt % to 30 wt % of an amorphous polymer. The carbon fiber has a nominal fiber diameter of from about 3 micron (μm) to about 13 μm. The composition has a surface resistivity that is at least 50% lower than that of a substantially identical reference composition that does not include the at least one nucleating agent. The combined weight percent value of all components does not exceed 100 wt. %, and all weight percent values are based on the total weight of the thermoplastic composition.
