Zachary A. August has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Bonding for additively manufactured thermoplastic composite structures
    Patent number: 10800113
    Abstract: Disclosed embodiments provide automated fiber placement techniques for fabrication of parts made from composite materials. Tape plies are wound around a mandrel while a polymer is dispensed on a tape ply shortly before compaction. A bead monitoring system monitors the size and placement of the bead on the tape ply and feeds back information to various process control systems to maintain an optimal bead size.
    Type: Grant

  • THERMOPLASTIC COMPOSITE PREPREG FOR AUTOMATED FIBER PLACEMENT
    Publication number: 20160023433
    Abstract: An improved thermoplastic composite prepreg tape is disclosed. The prepreg tape is optimized for high-speed, high quality in-situ consolidation during automated fiber placement. Embodiments of the prepreg tape have uniform dimensions (cross section, width, and thickness), uniform energy absorption, uniform surface roughness, and sufficient resin at the surface to affect a bond between layers. A scattering agent is used in a polymer surface layer to enable a combination of scattering and absorption in the polymer surface layer.

  • Fluid medium non-contact consolidation
    Patent number: 8911579
    Abstract: A pressure head for use in a fiber placement system for thermoplastic composite materials is disclosed. Plies of thermoplastic composite tape are placed onto a mandrel to form a shaped object. The pressure head includes a nozzle and at least one delivery tube for providing fluid medium mixture to the nozzle body, wherein the nozzle directs the fluid medium onto a surface of the shaped object thereby providing a pressure on the surface without direct physical contact of the nozzle with the plies of thermoplastic composite tape.
