JPS6442535A - Production of cast-in member - Google Patents

Abstract

PURPOSE:To prevent separation at interface between a cast-in member base body and fiber-reinforced metal by laminating the fiber to the cast-in member base body, press-forming these, next baking and arranging the fiber layer shrink- joining to the base body. CONSTITUTION:The cast-in member base body 2 is laid on a lower die 5, and a dividable insert 6 is arranged to fit an outer die 7. A cloth 8 composing of carbon long fiber, etc., and a carbon staple, etc., 9 are dipped into phenol, etc., and after laminating these fibers so as to enclose the cast-in member base body 2, the press-forming is executed by a preheated punch 10. Dividable presser tool 12 is set on obtd. fiber forming body 11 and the end part is fixed to the lower die 5 with a screw 13. This is baked in the atmosphere of N2 gas, etc. The fiber forming body 11 is brought into close contact with the base body 2 by press-forming and as it is shrunk at the time of baking, the gap between the fiber forming body 1 and the base body 2 is eliminated and both are perfectly brought into close contact with each other and firmly joined.
