Abstract
Abstract A method of producing a unidirectional fiber-reinforced composite material by covering bundles of an inorganic fiber having unidirectionally high elasticity and high strength with a wire-like, foil-like or knit-like material which is the same as, or different from, a matrix metal and is capable of being molten and diffused into said matrix metal, to thereby form a fiber body having an optional shape, volume and fiber density; placing the resulting fiber body in an appropriate location within a mold; pouring a molten matrix metal into said mold; and squeeze casting said molten matrix metal along with the fiber body to form the unidirectionally fiber-reinforced composite material while causing said covering material to melt and diffuse under heat of said molten matrix metal into the latter.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
110 words
A method of producing a unidirectional fiber-reinforced composite material including the steps of: covering bundles of an inorganic fiber having unidirectionally high elasticity and high strength, with a covering material which is capable of being molten and diffused into a matrix metal, to thereby form a fiber body having a defined shape, volume and fiber density; placing the resulting fiber body within a mold; pouring a molten matrix metal into said mold; and squeeze casting said molten matrix metal along with the fiber body to form the unidirectionally fiber-reinforced composite material while causing said covering material to melt and diffuse under heat of said molten matrix metal into the latter.
Claim 2
Independent Claim
110 words
A method of producing a unidirectional fiber-reinforced composite material including the steps of: covering bundles of an inorganic fiber having unidirectionally high elasticity and high strength, with a covering material which is capable of being molten and diffused into a matrix metal, to thereby form a fiber body having a defined shape, volume and fiber density; placing the resulting fiber body within a mold; pouring a molten matrix metal into said mold; and squeeze casting said molten matrix metal along with the fiber body to form the unidirectionally fiber-reinforced composite material while causing said covering material to melt and diffuse under heat of said molten matrix metal into the latter.
Claim 3
Dependent Claim
14 words
A method according to claim 1, wherein: said covering material is a wire-like material.
Claim 4
Dependent Claim
14 words
A method according to claim 1 wherein: said covering material is a foil-like material.
Claim 5
Dependent Claim
14 words
A method according to claim 1, wherein: said covering material is a knit-like material.
Claim 6
Dependent Claim
16 words
A method according to claim 1, wherein: said covering material is different from said matrix material.
Claim 7
Independent Claim
112 words
A method of producing unidirectional fiber-reinforced composite material including the steps of: forming a knit-like cloth from a longitudinal inorganic fiber having high elasticity and high strength plus a transverse fiber which is capable of being molten and diffused into said matrix metal; forming a fiber body having a defined shape and bulk density from said knit-like cloth; placing the resulting fiber body within a mold; pouring a molten matrix metal into said mold; and squeeze casting said molten matrix metal along with the fiber body to form the unidirectionally fiber-reinforced composite material while causing said transverse fiber to melt and diffuse under heat of said molten matrix metal into the latter.
Claim 8
Independent Claim
112 words
A method of producing unidirectional fiber-reinforced composite material including the steps of: forming a knit-like cloth from a longitudinal inorganic fiber having high elasticity and high strength plus a transverse fiber which is capable of being molten and diffused into said matrix metal; forming a fiber body having a defined shape and bulk density from said knit-like cloth; placing the resulting fiber body within a mold; pouring a molten matrix metal into said mold; and squeeze casting said molten matrix metal along with the fiber body to form the unidirectionally fiber-reinforced composite material while causing said transverse fiber to melt and diffuse under heat of said molten matrix metal into the latter.
Claim 9
Dependent Claim
27 words
A method for producing a unidirectional fiber-reinforced composite material as claimed in claim 6, wherein: said transverse fiber is of a material different than said matrix material.
