Abstract

A polymer composite includes a linear aliphatic semi-crystalline polyamide having on average 10 to 14 carbon atoms in the monomer units, or the compound thereof, an S glass fiber, and a core-shell impact modifier. The polymer composite can achieve higher stiffness and impact strength without impairing the transparency significantly. The polymer composite can be used as molding material.
