ALEXANDRIA, Va., Nov. 18 -- United States Patent no. 12,473,232, issued on Nov. 18, was assigned to Northwestern University (Evanston, Ill.).
"Carbon fiber-reinforced metakaolin-based geopolymer composites" was invented by Ange-Therese Akono (Evanston, Ill.) and Jiaxin Chen (Evanston, Ill.).
According to the abstract* released by the U.S. Patent & Trademark Office: "Methods for making carbon-fiber reinforced geopolymer composites are provided. The methods produce metakaolin-based geopolymer composites in which multiwalled carbon nanotubes and/or carbon nanofibers are well dispersed in an metakaolin-based geopolymer matrix. The mixing protocols of the methods used to produce carbon-fiber reinforced geopolymer composites produce composites ...
