Abstract
In a pressure infiltrating apparatus 20 according to the invention, an upper end of an inlet side orifice 23 in the drawing is formed to take a tapered convex shape and a lower end of an insertion hole of an intermediate orifice 25 in the drawing is formed to take a concave shape having a diameter gradually increased corresponding to the convex shape of the inlet side orifice 23. Consequently, a space A between the inlet side orifice 23 and the intermediate orifice 25 is set to be small without damaging the fluidity of a molten metal 11 between the inlet side orifice 23 and the intermediate orifice 25 in a bath container 22.
Claims2
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.
