Patent number: 11945942Abstract: A processing system for producing starch based expanded products useful as packing material for shipping, packaging and insulating applications. Generally, two processing steps for forming materials are involved. In a first step, dense pellets or granules are formed from starch and a plasticizing agent, such as a plasticizing polymer, for example, polyvinyl alcohol. The starch in the pellets is generally formed, for example with an extruder, into a thermoplastic or thermosetting form for further processing. The pellets generally have an individual density of at least about 70 lbs./cubic foot and a small size for convenient delivery for the second processing step. The second process step is based on the expanding of the material from an extruder with water as the expansion agent in which the dwell time in the extruder is short. The process is designed such that a less expensive single screw extruder is suitable for extruding the expanded material.Type: GrantFiled: January 15, 2021Date of Patent: April 2, 2024Assignee: NewStarch Solutions, LLCInventor: Matthew H.

Patent number: 11932736Abstract: A non-woven carbon fiber reinforced thermoplastic (CFRTP) composite object is formed by the variable frequency microwave (VFM) irradiation of a mixed fiber sheet of thermoplastic fibers, carbon fibers and wavy carbon nanotubes (CNTs). The mixed fiber sheets are prepared from a slurry of the thermoplastic fibers, carbon fibers, and wavy CNTs such that the wavy CNTs contact the carbon fibers and thermoplastic fibers. Upon irradiation with VFM radiation, the wavy CNTs generate heat and transfer the heat to the thermoplastic fibers, causing melting of the thermoplastic to form the matrix of the CFRTP composite object. The mixed fiber sheets can be combined alone or with other sheets to form laminar composites that are molded into objects and heated by VFM irradiation.Type: GrantFiled: May 4, 2021Date of Patent: March 19, 2024Assignees: Toyota Motor Engineering & Manufacturing North America, Inc., Vanderbilt UniversityInventors: Yuyang Song, Umesh N.
