Processing of 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 (HIP) 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 yarn through the small openings between the filaments. The continuous ceramic fiber/iron alloy composite in which the filaments are distributed uniformly can be produced by choosing adequate combination of the thickness of iron alloy powder sheet and the number of continuous ceramic fiber sheet.
