Publication number: 20230264960Abstract: Methods and apparatuses for continuous, large scale, commercially viable production of nanoforests. A roll-to-roll process passes a flexible substrate, including fibers and fabrics, through a furnace. Precursors are introduced in a growth zone in which a vertical or horizontal nanoforest of nanotubes or nanowires is grown on the substrate. Sensors and actuators with feedback control are provided for parameters such as substrate speed, substrate tension, furnace temperature, precursor flow rate, nanoforest thickness, and nanoforest. The furnace is preferably enclosed for environmental and safety purposes. The feed roll and take-up roll are disposed in housings can be attached to the furnace via airlocks, which enables rapid loading and unloading of the rolls using techniques well known in the industry while maintaining furnace conditions.Type: ApplicationFiled: July 9, 2021Publication date: August 24, 2023Applicants: University of Hawai'i, Goodman Technologies LLCInventors: Mohammad Naghi Ghasemi-Nejhad, Vamshi M.

Publication number: 20230114124Abstract: A reinforcement for increasing the strength and toughness and other properties in both transverse and in-piano directions for a composite material, and methods of manufacture therefor. The reinforcement has a layer of a nanoforest of vertical nanotubes or nanowires and a layer of horizontal nanotubes or nanowires. The reinforcement can be made by rolling a vertical nanoforest to produce a collapsed layer of horizontal nanofubes or nanowires, then growing a vertical nanoforest on the collapsed layer. The reinforcement can be grown directly on fibers which are used to reinforce the composite material, or alternatively Interleaved with layers of those fibers before the composite part is cured. The reinforcement and manufacturing method are compatible with almost any composite material in any shape, including epoxy, polymer, or ceramic matrix composites, or any manufacturing method, including prepreg, wet-layup and matrix film stacking.Type: ApplicationFiled: January 28, 2021Publication date: April 13, 2023Applicants: Goodman Technologies LLC, University of Hawai'iInventors: William A.

Patent number: 11274066Abstract: A method of making a ceramic matrix composite (CMC) part such as armor, in which a mixture, including a preceramic polymer, particles such as ceramic microparticles and/or nanoparticles, and organic compounds such as a surfactant and a solvent, are mixed to form a paste and printed or molded. The part is then cured and densified by polymer infiltration and pyrolysis (PIP) using the preceramic polymer with a varying amount and size of ceramic particles and different temperatures in some of the cycles. The CMC can contain silicon carbide, boron carbide, boron suboxide, alumina, or any other ceramic. The process is compatible with sacrificial materials, enabling the creation of parts with hollow portions or overhangs. The mixture preferably has a high loading of particles, for example between 70 wt % and 90 wt % of the mixture, in order to minimize shrinkage. Curing and pyrolyzing the part can be performed by microwaving.Type: GrantFiled: November 29, 2018Date of Patent: March 15, 2022Assignees: Goodman Technologies LLC, University of Hawai'iInventors: William A.

Publication number: 20210011047Abstract: Systems and methods are disclosed for generating temperature compensated acceleration data in analog and digital format from a torque balance accelerometer (TBA). During manufacture of the TBA, a calibration process is used for measuring a TBA scale factor and offset. After collecting scale and offset data, said data is loaded into the memory of the TBA. Field operation of the device includes: sensing a current temperature, retrieving the closest scale and offset correction factors from memory of the TBA, and performing linear interpolation to generate a temperature-compensated output for the TBA.Type: ApplicationFiled: April 30, 2020Publication date: January 14, 2021Inventor: William Goodman

Patent number: 10730203Abstract: A method of making a ceramic matrix composite (CMC) article by combining a preceramic polymer with one or more sized nanopowders and optional surfactants and/or solvents to form a mixture suitable for 3D printing, depositing the mixture on a mandrel, curing it to form a green body, and pyrolyzing the green body such that the nanocrystalline surface of the CMC article has sufficiently the same surface roughness and figure accuracy of the mandrel to enable the CMC article to be used without further polishing. The mixture can be a paste or slurry that is self supporting and exhibit pseudoplastic rheology. The preceramic polymer is preferably a precursor to SiC, and the nanopowders preferably comprise SiC. The article can be densified by using polymer infiltration pyrolysis, with or without nanoparticles. The curing and pyrolysis of the article can be performed with microwave radiation.Type: GrantFiled: September 20, 2018Date of Patent: August 4, 2020Assignee: Goodman Technologies LLCInventor: William A.

Publication number: 20200184169Abstract: Information is recorded in quick response codes. A hologram is made from quick response codes and provides three dimensions of information in a two-dimensional hologram. The holograms are used for recording large amounts of information in two dimensions. Multiple quick response codes containing copious information are created using different light wave frequencies in different quick response encoders. The multiple quick response codes are combined in a two-dimensional hologram that is used on labeling. The hologram is read by a hologram reader. Each quick response frequency layer is separated from the hologram. The quick response code is extracted from each layer. A quick response reader provides the information that has been recorded.Type: ApplicationFiled: December 4, 2019Publication date: June 11, 2020Inventors: James F.
