Abstract: Embodiments of the present invention include a novel interfacial surface generator (ISG) design comprised of helical channels and associated methods of using the new design. The novel design addresses processing challenges associated with conventional ISG designs used in layer multiplying coextrusion systems. Embodiments of the present invention may be used in either a static configuration or “active” configuration. In one active configuration, two counter-rotating cylindrical rods and/or moving belts may be used to induce drag, or Couette, flow. Conveyance of materials through the ISG may be due to pressure driven flow, drag flow, or a combination of these.

Abstract: A material with significant protection properties from galactic cosmic radiation and solar energetic particles. Hydrogen-rich benzoxazines which are particularly effective for shielding against such radiation. Benzoxazine resin meets the processing requirements for use with ultra-high molecular weight polyethylene fiber as a hydrogen-rich reinforcement: cure of the resin at 120° C. This highly reactive benzoxazine resin also exhibits low viscosity and adequate shelf life.
