METHOD FOR MANUFACTURING RACK HOUSING AND RACK HOUSING

摘要

Two laminating sheets each formed by laminating a carbon fiber sheet and a film of a thermoplastic resin are set on heating in an area of a mold corresponding to a tubular portion of a rack housing. The mold is clamped, the carbon fiber sheet is impregnated with the thermoplastic resin of the film, each of the two laminating sheets is pressed into a shape with a half tube corresponding to a half circumference of the tubular portion and connection portions at both ends of the half tube in a circumferential direction, and two half tubes are bonded together at the connection portions thereof to form the tubular portion.

1. A method for manufacturing a rack housing, the method comprising:
setting two laminating sheets on heating in an area of a mold corresponding to a three-dimensional shape of the rack housing with a tubular portion that covers a rack shaft, the area corresponding to the tubular portion, the laminating sheets each being formed by laminating a carbon fiber sheet and a film of a thermoplastic resin; and clamping the mold, impregnating the carbon fiber sheet with the thermoplastic resin of the film, pressing each of the two laminating sheets into a shape with a half tube corresponding to a half circumference of the tubular portion and connection portions at both ends of the half tube in a circumferential direction, and bonding two half tubes together at the connection portions thereof to form the tubular portion.
