Long fiber reinforced composites

摘要

A composite comprising from about 20 to 40 weight % of fiber reinforcing having a nominal length of not less than 1.25 cm, from about 1 to 10 weight % of a polar polymer and from 79 to 50 weight % of a polyolefin prepared using a single site catalyst has improved physical properties over comparable compositions made using polyolefins made using Ziegler Natta catalysts. The composites are suitable in many applications including construction and particularly in making concrete forms.
