Publication number: 20150044415Abstract: The present invention follows from a number of recent discoveries relating to cellulose fibrils and crystals. Unique properties of these compositions provide for novel structural materials that exhibit extremely high strength per unit of mass. Structures and articles first taught herein may be formed by computer numerically controlled processing, extruding, molding, shearing, weaving, and various additive manufacturing techniques, as well as by other more traditional procedures. These structures and articles may be used as a skin or core in composite constructions. These structures and articles can be used as free standing shells or panels. They may be made into intricate forms, particularly in three spatial dimensions with sonic elements in tension and some elements in compression to realize high performance functionalities. Cellulose matter is a dominate part of these compositions, making the articles fully biodegradable.Type: ApplicationFiled: August 12, 2013Publication date: February 12, 2015Inventors: John B.
