Zusammenfassung:	A fiber-reinforced polymer composition that contains a polymer matrix and a plurality of long reinforcing fibers that are distributed within the polymer matrix is provided. The polymer matrix contains a thermoplastic polymer and the polymer matrix constitutes from about 30 wt. % to about 90 wt. % of the composition. The fibers have a nominal diameter of from about 20 micrometers to about 40 micrometers and constitute from about 10 wt. % to about 70 wt. % of the composition. Furthermore, the polymer composition defines a surface that exhibits a ΔE value of from about 0.6 to about 3 after being exposed to UV light at a total exposure level of 2,500 kJ/m2 according to SAE J2412_201508.
