A fiber-reinforced composite material has an excellent design surface. The prepreg laminate includes at least prepregs [a] having reinforcing fibers impregnated with a resin, and a base material [b] not impregnated with a resin, wherein at least two of the prepregs [a] are stacked in succession, and both sides of the base material [b] are sandwiched by the prepregs [a].

Prepreg laminate and fiber-reinforced composite material, and method of producing fiber-reinforced composite material

A sandwich structure which is configured of skin layers each including at least one layer selected from among a metal layer, a fiber-reinforced resin layer (X) that includes continuous fibers and a matrix resin (A), and a fiber-reinforced resin layer (Y) that includes discontinuous fibers and a heat-curable matrix resin (B) and of a core layer including a flowable core layer that includes discontinuous fibers and a matrix resin (C), wherein the skin layers are constituted of a material which has a flexural modulus higher than that of the core layer, and a through part has been formed in a region that lies in at least some of the skin layers. In the sandwich structure, an upright part which projects in an out-of-plane direction of skin layer and which has high strength and a complicated shape such as a rib is obtained by an easy method.

Sandwich structure, shaped product, and production processes therefor

A laminate including a radio wave permeable member having a radio wave permeability; and a heat conducting member having an electromagnetic wave shielding property and/or a rigidity retaining member having an electromagnetic wave shielding property in the thickness direction of the radio wave permeable member; wherein the laminate has a radio wave permeable area solely constituted from the radio wave permeable member as a part of the laminate, and the radio wave permeable area is a thin area; and an integrally molded article using such laminate.

Laminate and integrally molded article

An FRP molded article molded by hot runner injection molding with a mixture of thermoplastic resin and reinforcing fibers of 0.1-7 mm in average length dispersed in the thermoplastic resin; and a hot runner injection molding method therefore. The molded article is preferable for use as a housing for electronic terminal equipment, cellular phones, etc.
