摘要: A prepreg includes; sizing agent-coated carbon fibers coated with a sizing agent; and a thermosetting resin composition impregnated into the sizing agent-coated carbon fibers. The sizing agent includes an aliphatic epoxy compound (A) and an aromatic compound (B) at least containing an aromatic epoxy compound (B1). The thermosetting resin composition includes a thermosetting resin (D) and a latent hardener (E), and optionally includes an additive (F) other than the thermosetting resin (D) and the latent hardener (E). The (a)/(b) ratio is within a predetermined range where (a) is the height of a component at a binding energy assigned to CHx, C—C, and C═C and (b) is the height of a component at a binding energy assigned to C—O in a C1s core spectrum of the surfaces of the sizing agent-coated carbon fibers analyzed by X-ray photoelectron spectroscopy.

摘要: The surface of a carbon fiber is electrochemically treated by a method to form nitrogen containing groups on the surface of the carbon fiber. The method comprises contacting a carbon fiber surface with an aqueous solution comprised of a non-cyclic aliphatic amine and water soluble inorganic hydroxide with said aqueous solution having a pH of at least 9. A positive electrical bias is then applied to the carbon fibers in the aqueous solution relative to another electrode in contact with the aqueous solution, wherein the positive electrical bias is at a voltage above the oxidation potential of water. The treated carbon fibers are useful for making epoxy reinforced carbon fiber composites.

摘要: A fiber sizing agent includes: a vinyl ester resin (A) having an alkoxy polyoxyalkylene structure and a urethane bond; and an aqueous medium. The fiber sizing agent has excellent fiber sizing properties for various fibers such as glass fibers and carbon fibers. A molded article obtained from a molding material including the fiber sizing agent is excellent in various physical properties such as bending strength, compressive strength, and interlaminar shear strength, and thus can be used, for example, for an automobile member, an aircraft member, a windmill member, and an industrial member.

摘要: One or more nanofiber yarns can be placed in contact with one or more nanofiber sheets. The nanofiber yarns, which include single-ply and multi-ply nanofiber yarns, provide added mechanical stability to a nanofiber sheet that decreases the likelihood of a nanofiber sheet wrinkling, folding, or otherwise becoming stuck to itself. Furthermore, the nanofiber yarns integrated with the nanofiber sheet can also act as a mechanism to prevent the propagation of tears through the nanofiber sheet. In some cases, an infiltrating material can be infiltrated into interstitial spaces defined by the nanofibers within both the nanofiber yarns and the nanofiber sheets. The infiltrating material can then form a continuous network throughout the nanofiber yarns and the nanofiber sheet.

摘要: Composite materials are provided that include a host material, nanoscale high conductive particles, and microscale high conductive particles. The nanoscale high conductive particles and the microscale high conductive particles may increase the through thickness thermal conductivity of the composite material by at least 4.0 W/(m·K), as compared to the same composite material without the nanoscale high conductive particles and microscale high conductive particles. Methods for making the composite materials herein also are provided.
