Abstract:
A pressure infiltrating apparatus comprising:a fiber bundle passing through a molten metal stored in a bath container in a pressure chamber filled with an inert gas via orifice thereby infiltrating the fiber bundle with the molten metal and coating an outer surface of the fiber bundle with the molten metal, the orifice including: an inlet side orifice for inserting the fiber bundle from a fiber bundle inlet side of the pressure chamber into the bath container; an outlet side orifice for leading a fiber reinforced metal composite wire infiltrated with the molten metal from a fiber bundle outlet side of the pressure chamber to an outside of the pressure chamber; and an intermediate orifice provided between the inlet side orifice and the outlet side orifice and serving to insert the fiber reinforced metal composite wire from the bath container into the pressure chamber, wherein a tip of the intermediate orifice side of the inlet side orifice has a convex shape and a tip on the inlet side orifice side of the intermediate orifice has a concave shape corresponding to the convex shape of the tip of the inlet side orifice.
