Title:
MANUFACTURE OF FIBER REINFORCED METAL COMPOSITE MATERIAL
Document Type and Number:
Japanese Patent JPH038552
Kind Code:
A
Abstract:

PURPOSE: To facilitate removal of a pipe body and also to prevent cutting and damage of fiber by accommodating a reinforcing fiber aggregate in the pipe body having spiral groove at outer circumferential face, charging in a mold, pouring and pressurizing molten metal into the pipe body, impregnating into the aggregate and releasing from the mold after solidifying and stripping off the pipe body along the groove.

CONSTITUTION: The material forming the aggregate 2 of reinforcing fiber around the core metal 8 is accommodated in the pipe body 4 having the groove 9 extending as spiral state to longitudinal direction at the outer circumferential face and charged into the metallic mold 1. Then, granule 3 is packed into be tween the metallic body 1 and the pipe body 4. Successively, the molten metal 5 as the matrix is poured into the pipe body 4 and pressurized with a plunger 6 to impregnate this into the aggregate 2, and after solidifying the molten metal 5, the metallic mold 1 and a base 7 are separated to discharge the granule 3, and after taking out the pipe body 4 from the metallic mold 1, the pipe body 4 is stripped off so as to remove along the groove 9 to obtain the FRM 10.
