PRESS MOLDING PRODUCTION METHOD

Номер: WO2018021488A1
Принадлежит:

The present invention addresses the problem of providing a method for producing a fiber-reinforced resin molding by cold press-molding a fiber-reinforced resin material made of a thermoplastic resin and reinforcing fibers, wherein the fiber-reinforced resin molding has excellent moldability such that thin-walled moldings are obtained, the numerical value of bending strength divided by grammage (weight reduction index) is large, and external appearance is excellent. Said problem can be solved by a method for producing a fiber-reinforced resin molding by cold press-molding a fiber-reinforced resin material comprising reinforcing fibers and a thermoplastic resin using a mold with an upper mold and a lower mold. The fiber-reinforced resin molding production method is characterized in that the respective parameters for heating temperature, charge time, air-cooling rate, pressurization time, flow-stopping temperature, cooling rate during pressing, and time during which molding is possible simultaneously ...

POLYCARBONATE RESIN COMPOSITION AND CIRCUIT MOLDED ARTICLE FOR COMMUNICATION DEVICES

Номер: WO2022075328A1
Принадлежит:

The present invention provides a polycarbonate resin composition which exhibits, in addition to good strength and low dielectric characteristics, excellent long-term durability and good adhesion to a metal thin film during the formation of a circuit. A polycarbonate resin composition according to the present invention contains from 10 parts by weight to 5,000 parts by weight of (B) a circuit formation stabilizer (component B) relative to 100 parts by weight of (A) an aromatic polycarbonate resin (component A) other than the component B. This polycarbonate resin composition may contain, as additional components, (C) a flame retardant (component C), (D) a fluorine-containing anti-drip agent (component D), (E) an additive for laser irradiation three-dimensional circuit molding (component E), (F) an inorganic filler (component F), (G) a laser marking additive (component G), (H) a rubbery polymer (component H), and the like.

FIBER-REINFORCED RESIN MOLDED BODY HAVING EMBOSSED PORTION ON AT LEAST PART OF SURFACE THEREOF AND METHOD FOR PRODUCING SAME

Номер: WO2017119516A1
Автор: MITSUNAGA, Masaki
Принадлежит:

Provided is a fiber-reinforced resin molded body containing reinforcing fibers and a thermoplastic resin and having an embossed portion on at least part of the surface thereof. The fiber-reinforced resin molded body is characterized in that the ratio between the maximum reflectance (R) and the full width half maximum (H) thereof, as measured by variable angle photometry, satisfies formula (1): R/H ≤ 0.034 × R - 0.15, where R denotes the maximum reflectance (%) and H denotes the full width half maximum (°).
