Patent number: 10124402Abstract: A method for manufacturing carbon fiber reinforced aluminum composites is provided. Particularly, the method uses a stir casting process during a melting and casting process and reduces a contact angle of carbon against aluminum by inputting carbon fibers while supplying a current to liquid aluminum to induce the carbon fibers to be spontaneously and uniformly distributed in the liquid aluminum and inhibits a formation of an aluminum carbide (Al4C3) phase on an interface between the aluminum and the carbon fiber, thereby manufacturing carbon fiber reinforced aluminum composites having excellent electrical, thermal and mechanical characteristics.Type: GrantFiled: March 3, 2017Date of Patent: November 13, 2018Assignee: Korea Institute of Science and TechnologyInventors: Jin Kook Yoon, Kyung Tae Hong, Gyeung Ho Kim, Young Jun Choi, Geun Hun Oh

Patent number: 10087557Abstract: Provided is a method for producing carbon nanofibers having excellent conductivity, crystallinity and dispersibility. A method for producing carbon nanofibers, which uses an activated species mainly composed of cobalt as a catalyst, while using carbon monoxide as a carbon source. The catalyst is obtained by having a carrier, which is composed of an oxide having a specific surface area of 0.01-5 m2/g and containing magnesium, support 3-90% by mass of the activated species. By controlling the reaction temperature, the carbon monoxide partial pressure and the gas flow rate of the carbon monoxide, CNF having more excellent conductivity, crystallinity and dispersibility can be produced, thereby obtaining carbon nanofibers having excellent conductivity, crystallinity and dispersibility.Type: GrantFiled: July 25, 2016Date of Patent: October 2, 2018Assignee: DENKA COMPANY LIMITEDInventors: Hitoshi Kaneko, Toru Arai, Yoko Horikoshi, Ayumu Tsukamoto

Patent number: 10061462Abstract: A method and apparatus are provided for a touch sensor made from a combination of conductive and non-conductive fibers. The fibers are woven into a fabric wherein non-conductive fibers keep horizontal conductive fibers from contacting vertical conducting fibers unless a touch is applied. The conductive fibers are grouped into horizontal and vertical strips and the fibers in a strip are connected together throughout the fabric. The ends of the strips are connected to control electronics that drive signals to the sensor fabric and measure signals from the sensor fabric to determine touch locations and touch contact areas.Type: GrantFiled: January 18, 2015Date of Patent: August 28, 2018Inventor: William James McDermid

Patent number: 10047015Abstract: A method and apparatus for forming a plurality of fibers from (e.g., CVD) precursors, including a reactor adapted to grow a plurality of individual fibers; and a plurality of independently controllable lasers, each laser of the plurality of lasers growing a respective fiber. A high performance fiber (HPF) structure, including a plurality of fibers arranged in the structure; a matrix disposed between the fibers; wherein a multilayer coating is provided along the surfaces of at least some of the fibers with an inner layer region having a sheet-like strength; and an outer layer region, having a particle-like strength, such that any cracks propagating toward the outer layer from the matrix propagate along the outer layer and back into the matrix, thereby preventing the cracks from approaching the fibers.Type: GrantFiled: January 18, 2013Date of Patent: August 14, 2018Assignee: FREE FORM FIBERS, LLCInventors: Joseph Pegna, John L.
