Claim 4:
5. A pellet comprising a thermoplastic composite comprising:
a. about 80 to 5 vol. % of a polymer phase comprising a thermoplastic polymer with a density of less than about 1.9 g-cm−3 and
b. about 20 to 95 vol. % of a dispersed fiber phase comprising a reinforcing fiber with an aspect ratio of 1 to 50 the dispersed phase comprising about 0.2-6 wt. % of a coating of at least one interfacial modifier;
wherein the composite material has a Young's modulus of greater than 700 MPa; the interfacial modifier provides a coating on the dispersed fiber that can form a close association between the fiber and polymer and covalent bonding between fiber and polymer is not formed.
