Patent number: 9969108Abstract: A method is provided for forming a substantially uniaxially-oriented, high content cellulose nanocrystal film. The method includes providing a plant-biomass-based suspension of cellulose nanocrystals and altering the pH of the cellulose nanocrystals to a substantially neutral pH. The suspension is sheared at a shearing rate. The method further includes orienting the cellulose nanocrystals in a substantially axial direction and removing water from the sheared cellulose nanocrystal suspension. As a result, a substantially uniaxially-oriented cellulose nanocrystal film is formed.Type: GrantFiled: February 17, 2016Date of Patent: May 15, 2018Assignees: PURDUE RESEARCH FOUNDATION, THE UNITED STATES OF AMERICA AS REPRESENTED BY THE SECRETARY OF AGRICULTUREInventors: Jeffrey P. Youngblood, Robert J. Moon, Alex Reising

Patent number: 9944026Abstract: The present disclosure provides a method of repairing a damaged portion of a panel formed of composite material. The method includes preparing the damaged portion for repair and applying a pressure responsive adhesive layer to substantially cover the damaged portion. The method also includes disposing a vacuum-assisted resin transfer molding repair patch assembly to substantially cover the damaged portion and substantially covering the repair patch assembly with a vacuum bag assembly. Resin is introduced into and impregnates the repair patch assembly. The repair patch assembly is cured after being impregnated.Type: GrantFiled: May 4, 2012Date of Patent: April 17, 2018Assignee: PURDUE RESEARCH FOUNDATIONInventors: R.
