Abstract: A method of producing thermoplastic resin composite material in which a main base material containing thermoplastic resin and a sheet-like shaped auxiliary base material are integrally molded and are made into composite material. The production method includes the steps of: heating the auxiliary base material (step S1); disposing the heated auxiliary base material in a mold (step S2); disposing the main base material in the mold via the auxiliary base material (step S3); closing the mold, and pressing together and integrally molding the auxiliary base material and the main base material (step S4); and taking out the integrally-molded thermoplastic resin composite material from the mold.

Abstract: A method for measuring a fiber orientation degree includes: irradiating a sample formed of a composite material containing discontinuous carbon fibers with an X-ray to acquire an X-ray diffraction image; calculating an angle (2θ)A of a peak originating from a crystal face of graphite; calculating a correction coefficient δ of a thickness of the sample; calculating an upper limit (2θ)B of the peak of the crystal face of graphite; calculating a diffraction sensitivity IC(ϕ) of the peak originating from the crystal face of graphite by correcting an integrating range with the correction coefficient δ and integrating the X-ray diffraction image with respect to a diffraction angle (2θ); and calculating a fiber orientation degree Sd(β) by the method of Hermans from the diffraction sensitivity IC(ϕ).

Abstract: A molding method and a molding system for improving a molding speed of a resin molded member. In the method, firstly a thermoplastic resin composite material is filled in a metal mold (i.e., at time T0), and subsequently a mold-clamping process gets started. As the mold-clamping process progresses, a first decompression circuit starts to decompress an inside of a cavity when the cavity is closed by a sealing member provided on the metal mold. Then, as the mold-clamping process further progresses, the thermoplastic resin composite material thus filled in the metal mold contacts an upper mold of the metal mold (i.e., at time T2). After that, a second decompression circuit starts to decompress the inside of the cavity, thereby to complete the mold-clamping process (i.e., at time T3).

Abstract: A method for producing a preparation for fiber length measurement includes: a preliminary dispersion process of adding fibers and a dispersion medium with a viscosity of 500 Pa·s to 10,000 Pa·s to a sealable container so as to give a concentration of the fibers of 0.1% by mass or less and shaking the container to prepare a preliminary dispersion liquid; a dispensing process of dispensing part of the preliminary dispersion liquid to another sealable container; a dilution process of adding the dispersion medium to the dispensed preliminary dispersion liquid so as to give a concentration of the fibers of 0.005% by mass or less and shaking the container to prepare a dispersion liquid for measuring fiber length; and a casting process of spreading part of the dispersion liquid for measuring fiber length onto a base having light transparency.

Abstract: A method of manufacturing a molded product of fiber-reinforced thermoplastic resin includes: mixing i) a first fiber-reinforced thermoplastic resin material manufactured by fusing and kneading a thermoplastic resin and fiber and extruding a resultant composite and ii) a second fiber-reinforced thermoplastic resin material manufactured by impregnating a fiber with a thermoplastic resin; heating the first and second fiber-reinforced thermoplastic resin materials thus mixed; and molding the first and second fiber-reinforced thermoplastic resin materials thus heated. An average value of a length of the fiber included in the second fiber-reinforced thermoplastic resin material is larger than an average value of a length of the fiber included in the first fiber-reinforced thermoplastic resin material.
