  • Patent number: 11833803
    Abstract: A fiber reinforced plastic molded body includes a layered body, a resin member, unidirectional fiber reinforced resins each constituted from a unidirectional continuous fiber, a matrix resin, and a woven fabric fiber reinforced resin of one or two or more layers, wherein when the layered body is divided into equal halves in its thickness direction, an amount of the resin member present in a region (R1) which is a side from a dividing center line whereon the woven fabric fiber reinforced resin is layered is referred to as Am1, and an amount of the resin member present in a region (R2) which is a side whereon the woven fabric fiber reinforced resin is not layered is referred to as Am2, Am2/Am1 is 2 to 25.

  • Publication number: 20130280479
    Abstract: A carbon-fiber-reinforced plastic molded article including a laminate with at least two layers including a unidirectionally continuous-carbon-fiber-reinforced sheet in which continuous carbon fiber bundles are arranged in a predetermined one direction, characterized in that, when the carbon fibers of an outermost unidirectionally continuous-carbon-fiber-reinforced sheet forming a design surface of the molded article are observed at the design surface, the area fraction of regions where the proportion of carbon fibers which are inclined at angles of 3° or more to the predetermined one direction is 0.5% or more is 20% or less relative to the whole area of the design surface.

  • Patent number: 8415007
    Abstract: A layered product which is a molded object including a thermoset resin layer, a thermoplastic resin layer, and reinforcing fibers comprising many continuous filaments, wherein the thermoset resin layer has been united with the thermoplastic resin layer at the interface between these layers, the resin of the thermoset resin layer and the resin of the thermoplastic resin layer each having an irregular surface shape at the interface, and a group of filaments among the reinforcing fibers are in contact with at least the resin of the thermoset resin layer and the other group of filaments among the reinforcing fibers are in contact with at least the resin of the thermoplastic resin layer, and that side of the thermoplastic resin layer which is opposite to the interface being a surface of the molded object.
