  • Patent number: 10647065
    Abstract: A method of making a composite article involves first forming an intermediate substrate. The intermediate substrate can be formed from fibers and an uncured thermoset polymer composition followed by partial cure, or from fibers and an uncured thermoset polymer composition followed by cure of the thermoset polymer composition and deposition of a thermoplastic on the surface of the substrate, or from fibers and an uncured thermoset polymer composition followed by cure and exposure of the substrate to organic solvent, a plasticizer, moisture, and/or heat. The intermediate substrate prepared according to any of the above techniques is then subjected to cold gas spray deposition to deposit a metal layer onto the intermediate substrate. In the case where the substrate was formed by partially curing a thermoset polymer composition, the metal-coated partially-cured thermoset polymer substrate is then fully cured.

  • Patent number: 9541000
    Abstract: A method for reducing emissions from an engine includes generating a light hydrocarbon fuel fraction and combusting the light hydrocarbon fuel fraction in place of the fuel. The light hydrocarbon fuel fraction is generated by heating the fuel and flowing the fuel through a plurality of hollow fiber superhydrophobic membranes in a membrane module. Each hollow superhydrophobic membrane comprises a porous support and a superhydrophobic layer free of pores that extend from one side of the superhydrophobic layer to the other. Vapor from the fuel permeates the superhydrophobic membranes and enters a distillate collection chamber, producing a distilled fuel in the distillate collection chamber and a residual fuel within the hollow fiber superhydrophobic membranes. The residual fuel is removed from the membrane module and cooled to produce a cooled residual fuel.
