Processing of a Continuous Ceramic Fiber/Iron Alloy Composite

抄録

Processing of a continuous ceramic fiber/iron alloy composite by powder metallurgy was investigated. The preparation of continuous ceramic fiber/iron alloy composite is feasible by hot isostatic pressing of a laminate of iron alloy powder sheets, prepared from a doctor blade method, and continuous ceramic fiber sheets. It is necessary to choose suitable temperature and pressure which enable iron alloy to penetrate into ceramic yarn through the small openings between the fibers. The continuous ceramic fiber/iron alloy composite in which fibers are uniformly dispersed can be produced by choosing an appropriate combination of the thickness of iron alloy powder sheet and the number of continuous ceramic fiber sheet.
