Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
51 words
A resin composite material containing graphite fiber which comprises a synthetic resin matrix and an intercalated compound of graphite fiber and bromine, said graphite fiber having a structure characterized by that the hexagonal network planes of carbon atoms are oriented substantially parallel to the fiber axis and like the annual ring.
Claim 2
Dependent Claim
51 words
A resin composite material containing graphite fiber which comprises a synthetic resin matrix and an intercalated compound of graphite fiber and bromine, said graphite fiber having a structure characterized by that the hexagonal network planes of carbon atoms are oriented substantially parallel to the fiber axis and like the annual ring.
Claim 3
Dependent Claim
61 words
A resin composite material containing graphite fiber according to Claim 1, wherein the graphite fiber is one which is produced by bringing a hydrocarbon compound into contact, at a high temperature, with a metallic catalyst in the form of ultrafine particles supported on a substrate to yield carbon fiber grown in the gas phase, and subsequently graphitizing thus obtained carbon fiber.
Claim 4
Dependent Claim
58 words
A resin composite material containing graphite fiber according to Claim 1, wherein the graphite fiber is one which is produced by bringing a hydrocarbon compound into contact with a metallic catalyst in the form of ultrafine particles suspended in a high-temperature zone to yield carbon fiber grown in the gas phase, and subsequently graphitizing thus obtained carbon fiber.
Claim 5
Dependent Claim
24 words
A composite material according to Claim 2 or 3, wherein the metallic catalyst is one which is selected from iron, nickel, and iron-nickel alloy.
Claim 6
Dependent Claim
28 words
A composite material according to any one of Claims 2 to 4, wherein the metallic catalyst is one which has a particle diameter of 100 to 300 Å.
Claim 7
Dependent Claim
27 words
A composite material according to any one of Claims 2 to 5, wherein the hydrocarbon is brought into contact with the metallic catalyst at 900 to 1500°C.
Claim 8
Dependent Claim
27 words
A composite material according to any one of Claims 2 to 6, wherein the carbon fiber is graphitized at 1500 to 3500°C for 10 to 120 minutes.
Claim 9
Dependent Claim
30 words
A composite material according to Claim 1, wherein the intercalated compound of graphite fiber and bromine is produced by bringing graphite fiber into contact with bromine at 0 to 50°C.
