Title:
PRODUCTION OF COMPOSITE REINFORCING MATERIAL FOR PRODUCING FUNCTIONALLY GRADIENT METAL-BASED COMPOSITE MATERIAL
Document Type and Number:
Japanese Patent JPH0718352
Kind Code:
A
Abstract:
PURPOSE: To easily produce a composite reinforcing material contg. a powdery reinforcing material disposed with a gradient for producing a functionally gradient metal-based composite material using a powder reinforcing material.
CONSTITUTION: A slurry prepd. by dispersing whiskers or inorg. fine particles in water contg. an inorg. binder and a slurry prepd. by dispersing heat resistant inorg. fibers in water contg. an inorg. binder are fed under mixing into a mold for dehydration molding having a horizontal filtering face and dehydration molding is carried out. At this time, the feed ratio between the slurries is varied with the lapse of time. The resulting molded body is dried and fired to obtain a porous molded body.
