FIBER-REINFORCED COMPOSITE MATERIAL, METHOD OF PRODUCING SAME, AND ELEVATOR COMPONENT MEMBER AND ELEVATOR CAR THAT USE SAME

摘要

Provided is a method of producing a fiber-reinforced composite material, involving impregnating a fiber structure with a resin by using the pressure difference between a vacuum pressure and an atmospheric pressure and thereafter curing the resin, the method comprising: impregnating a mixture of a bromine-containing resin 22 and a powdered flame retardant 21 that contains at least one component selected from aluminum hydroxide and magnesium hydroxide and has an average particle size in the range of 0.1 to 20 μm into a fiber structure 10 that has a mode value for the size of fiber surrounded individual openings in the range of 0.03 to 3 mm2 and an opening area percentage in the range of 0.1 to 10%, from a surface direction of the fiber structure 10, to unevenly distribute the powdered flame retardant 21 in a surface layer of the fiber structure 10. The present invention can simply and conveniently produce a highly flame-retardant and lightweight fiber-reinforced composite material that exhibits a high strength.

1. A method of producing a fiber-reinforced composite material, the method comprising:
impregnating a carbon fiber structure with a resin by using a pressure difference between a vacuum pressure and an atmospheric pressure, and curing the resin, wherein said impregnating comprises impregnating a mixture of a bromine-comprising resin and a powdered flame retardant that comprises at least one component selected from the group consisting of aluminum hydroxide and magnesium hydroxide and has an average particle size of from 0.1 to 20 μm, into the carbon fiber structure that has a mode value for a size of carbon fiber surrounded individual openings of from 0.03 to 3 mm2 and an opening area percentage of from 0.1 to 10% from a surface direction of the carbon fiber structure, to unevenly distribute the powdered flame retardant in a surface layer of the carbon fiber structure, and a ratio of a volume occupied by the carbon fiber structure in the fiber-reinforced composite material is from 25 to 85% by volume.
