Claim Text:
1. A fiber reinforced thermoplastic composite, comprising a continuous thermoplastic polymer phase comprising: a) a polyetherimide having a molecular weight of at least 40,000 Daltons; and a polyetheretherketone having a melt viscosity less than 150 Pascal-seconds (Pa-s) when determined under the conditions of 400° C. and a shear rate of 1000/s; and b) a dispersed phase comprising a plurality of polyacrylonitrile-based carbon fibers having a tensile modulus in the range of from 38 to 48 MSI dispersed within the continuous thermoplastic polymer phase; and wherein the composite exhibits a specific modulus of at least about 25; wherein the composite exhibits a tensile strength of at least about 226 MPa; wherein the composite exhibits a melt mass-flow rate (“MFR”) of at least 10 g/min when determined under the conditions of 380° C. and 6.6 kg mass; and wherein the composite exhibits a heat release profile characterized by a 2 minute total heat release less than about 65 kW min/m
