Abstract:
1. Composite pellets produced by a method comprising: extruding a blended mixture comprising molten thermoplastic resin and reinforcing fibers through a die orifice with a cross-sectional shape having a rectangular envelope with an aspect ratio of about 1.5:1 to 5:1, wherein the reinforcing fibers have a largest dimension which is no more than about 90% of a width of the die orifice; and cutting the extruded mixture to form pellets having an axial length to cross-sectional width ratio of about 0.25:1 to 5:1; wherein the reinforcing particulates comprise carbon fibers having a diameter of about 5 to 20 microns and an aspect ratio of about 10 to 200; and the thermoplastic polymeric resin comprises polyetheretherketone, polyetherketoneetherketoneketone, polyetherimide, polyethersulfone, polyphthalamide or a combination thereof.
