In a method for producing a fiber-reinforced resin molded body () by heat-compressing fiber substrates (A toD) together with a thermosetting resin () so that the thermosetting resin () is impregnated into the fiber substrates (A toD) and cured, a thermosetting resin powder (A) is disposed in contact with at least one surface of the fiber substrates (A toD), the fiber substrates (A toD) are heat-compressed together with the thermosetting resin powder (A) by a mold () so that the thermosetting resin powder (A) is melted, impregnated into the fiber substrates (A toD), and cured. Also disclosed is a fiber-reinforced resin molded body as well as a vehicle or airframe including a fiber-reinforced resin molded body.

A fiber-reinforced molded productincludes a core material, a fiber reinforcing materiallaminated on at least one surface of the core material, and a surface materiallaminated on the fiber reinforcing material. The core material, the fiber reinforcing material, and the surface materialare integrated. The fiber reinforcing materialincludes a fiber fabricA and a thermosetting resinB andB impregnated into the fiber fabricand cured. The surface materialincludes a porous sheetA having open cells, the number of the cells being 8 to 80 cells/25 mm, and the thermosetting resinB andB moved out of the fiber fabricinto the porous sheetA and cured, and the surface materialA has a surface roughness Rz of 30 &#x3bc;m or less.

Fiber-reinforced molded product and method for manufacturing the same

An object is to provide a fiber-reinforced molded product that is superior in terms of lightness, thinness and high rigidity. A fiber-reinforced molded product has a core materialand a fiber-reinforced materialprovided on both surfaces of the core material. The core materialis formed by impregnating a thermosetting resin foam having open cells with a first thermosetting resin and curing the thermosetting resin while compressing the impregnated thermosetting resin foam with a compression rate of 200 to 5000. The fiber-reinforced materialis formed by impregnating a carbon fiber fabric with a second thermosetting resin and curing the second thermosetting resin. A resin ratio of the first and second thermosetting resins after the impregnation is 50 to 80. The core materialand the fiber-reinforced materialare formed as a unitary body by curing the first and second thermosetting resins.

A pattern is formed by applying a coating composition containing magnetic particles to an article so that a coating film is formed, and a plurality of sheet form magnets are placed along the front surface of this coating film. Adjacent sheet form magnets are arranged in such a state that the magnetic poles on the front surface and the magnetic poles on the back surface are different between adjacent sheet form magnets, and side surfaces of the sheet form magnets contact each other. The coating composition contains a thermoplastic resin, magnetic particles with flaky form and a specific low boiling point solvent and a specific high boiling point solvent. A magnetic field is applied to the coating film by the sheet form magnets, so that the magnetic particles in the coating film are oriented by the magnetic field and the magnetic particles are oriented substantially parallel to the front surface of the coating film above the contact portions between the sheet form magnets. Light is reflected from the magnetic particles in the coating film so that a pattern is formed.

Pattern forming method

A test cell for magnetic immunoreaction assay, comprising a polymer having a quantity of residual magnetism of 15 pT or less, when a magnetic field is applied under a magnetic field of 0.1 T, and with a distance between a sample and a SQUID sensor being set at 1.5 mm, and a method for producing the test cell are provided. A test cell for magnetic immunoreaction assay, comprising a polymer having a metal content of 30 ppb or less, and a method for producing the test cell are also provided. A magnetic signal detected from a magnetic marker to be measured is not buried in or lost to the residual magnetic signal of the test cell itself, but data discrimination can be made clearly.
