Abstract
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 propylene polymer and constitutes from about 30 wt. % to about 90 wt. % of the composition. The fibers constitute from about 10 wt. % to about 70 wt. % of the composition. Further, the polymer composition exhibits a spiral flow length of about 450 millimeters or more as determined in accordance with ASTM D3123-09 and a volatile organic content of about 100 micrograms per gram or less as determined by VDA 277.
