Publication number: 20240043636Abstract: A prepreg is provided. The prepreg includes sizing agent-coated carbon fibers and a thermosetting resin composition (B) impregnated between the sizing agent-coated carbon fibers. The sizing agent includes a reactive component (A) having at least three reactive groups per molecule: (i) two or more first functional groups capable of reacting with the thermosetting resin composition (B), and (ii) at least one second functional group different from the two or more first functional groups (i). The second functional group includes at least one of amide, imide, urethane, urea, carbonyl, ester, sulfonyl, aromatic ring, or combinations thereof. The thermosetting resin composition (B) includes at least one thermosetting resin other than an epoxy resin and has a glass transition temperature of 220° C. or more after being cured.Type: ApplicationFiled: December 2, 2021Publication date: February 8, 2024Applicant: Toray Composite Materials America, Inc.Inventors: Alfred P. Haro, Jonathan C. Hughes, Naoki Matsuura, Jeffrey P. Sitthi, Hiroshi Kobayashi, Toshiya Kamae

Publication number: 20240010805Abstract: A fiber reinforced prepreg comprising reinforcement fibers; particles (D1) and (D2); and a thermosetting resin composition is provided. The resin includes maleimide compound (A), and co-monomer (B). Co-monomer (B) has least one of an alkenylphenol, an alkenylphenoxy, or a diamine group. Particles (D1) are smaller than (D2) and particles (D1) and (D2) are insoluble in the thermosetting resin. Particles (D1) range in diameter from 1 to 10 microns and have a mode on a volume basis from 3 to 6 microns and are present from 3 to 12 percent by volume of the thermosetting resin. Particles (D2) range from 10 to 100 microns diameter and a mode of 20 to 60 microns and are present from 1 to 6 percent by volume of the thermosetting resin composition. After cure, at least 90% by volume of particles (D1) and (D2) remain in the prepreg interlayers.Type: ApplicationFiled: December 2, 2021Publication date: January 11, 2024Applicant: Toray Composite Materials America, Inc.Inventors: Madelyn Milligan, Jonathan C. Hughes, Alfred P. Haro, Toshiya Kamae, Naoki Matsuura, Koji Furukawa

Patent number: 7052586Abstract: We make particulates, especially magnetic Fe—Co alloys having high magnetic permeability, of controlled dimensions, especially those having a narrow thickness size distribution centered around a median or target thickness in the range of about 0.1–1.0 ?m, using electrodeposition typically on a smooth (polished) titanium cathode. Our preferred continuous process uses a rotating drum cathode inside a fixed anode to grow flakes and to produce them automatically by inherent instability in the deposited film. The drum preferably rotates about a substantially vertical axis. The particulates shed (slough off) into the electrolyte (because of mismatch between the cathode surface and the plated metal or alloy at the molecular level) where they are separated in a magnetic separator or other suitable device. If the flakes are soft iron or iron-cobalt alloys, the drum generally is titanium or titanium alloy.Type: GrantFiled: February 11, 2003Date of Patent: May 30, 2006Assignee: The Boeing CompanyInventors: Glen L. Rasmussen, Micheal E. Dickson, Robert J. Miller, Mary J. Nelson, Jonathan C. Hughes, Diane C. Rawlings
