  • Patent number: 11905404
    Abstract: Provided is a resin composition that is capable of producing a cured product having excellent environmental suitability, high strength, and excellent flame retardancy, and that is suitably usable as a matrix resin for fiber-reinforced plastics. A resin composition contains (A) an epoxy resin, (B) a cyanate resin, (C) an aromatic amine curing agent that is liquid at 25° C., and (D) a phosphorus-containing compound represented by formula (1). Preferably, in formula (1), R1 and R2 each independently represent an alkyl group or an aryl group, and X and Y are an oxygen atom.

  • Patent number: 11649319
    Abstract: The present invention provides a resin composition for a fiber-reinforced plastic, the resin composition including a cyanate ester (A), an epoxy resin (B), and an aromatic amine-based curing agent that is liquid at 25° C. (C), wherein the average number of cyanate groups in the cyanate ester (A) is 2.1 or greater, and/or the average number of epoxy groups in the epoxy resin (B) is 2.1 or greater. A fiber-reinforced plastic that is produced using this composition and a reinforcing fiber has favorable heat resistance and excellent tensile and bending properties, and therefore can be applied to a wide variety of fields including transport vehicles such as ships, automobiles, and aircrafts, sporting goods, building materials such as sinks and window frames, as well as industrial machinery and materials such as high-pressure gas tanks and blades for wind power generation.

  • Publication number: 20180361685
    Abstract: A molding apparatus reduces waviness or deformation of fibers. The molding apparatus includes a fiber feeder (7) that feeds fibers (5) to a lamination area (32) long in a first direction, a resin composition feeder (11) that feeds a resin composition (9) to the lamination area (32), an impregnator (17) that impregnates the fibers (5) fed to the lamination area (32) with the resin composition (9), a curing accelerator (13) that accelerates curing of the resin composition (9) fed to the lamination area (32) while the fibers (5) fed in the lamination area (32) are being tensioned, and a transporter (15) that relatively moves the devices (7, 11, 17, and 13) in the first direction with respect to the lamination area (32). The resin composition (9) contains an epoxy resin (A), a cyanate resin (B), and an aromatic amine curing agent (C) that is liquid at 25° C.
