LONG FIBER-REINFORCED PROPYLENE COMPOSITION FOR USE IN A THIN PART

A fiber-reinforced polymer composition that comprises a polymer matrix that contains a propylene polymer is provided. The polymer matrix constitutes from about 30 wt.% to about 80 wt.% of the composition, and a plurality of long reinforcing fibers that are distributed within the polymer matrix. The fibers constitute from about 20 wt.% to about 70 wt.% of the composition. The polymer composition exhibits a spiral flow length of about 450 millimeters or more as determined in accordance with ASTM D3121-09, and after aging at a temperature of 150 deg c for 1,000 hours, a Charpy unnotched impact strength greater than about 15 kJ/m2 as determined at a temperature of 23 deg c in accordance with ISO Test No. 179-1:2010. 提供了一种纤维增强的聚合物组合物，其包含含有丙烯聚合物的聚合物基质。聚合物基质占组合物的约30wt％至约80wt％，和多个长增强纤维分布在聚合物基质内。纤维占组合物的约20wt％至约70wt％。该聚合物组合物表现出根据ASTM D3121-09测定的约450毫米或更大的螺旋流动长度，在温度150℃老化1000小时后，根据ISO Test No.179-1:2010在23℃的温度测定的大于约15kJ/m的简支梁无缺口抗冲强度。
