Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
50 words
A fiber reinforced article composed of a matrix of fibrous carbon material bonded together by a deposited pyrolytic material and having the residue of a carbonizable filler material deposited on said pyrolytic material, said residue produced by initially depositing and subsequently carbonizing said carbonizable filler material on said pyrolytic material.
Claim 2
Dependent Claim
50 words
A fiber reinforced article composed of a matrix of fibrous carbon material bonded together by a deposited pyrolytic material and having the residue of a carbonizable filler material deposited on said pyrolytic material, said residue produced by initially depositing and subsequently carbonizing said carbonizable filler material on said pyrolytic material.
Claim 3
Dependent Claim

Claim 11
Independent Claim
78 words
A method of producing fiber reinforced carbon articles by: (a) forming a fibrous carbon material into a shape without the use of a binder material, (b) infiltrating said fibers with a pyrolytic material in a manner to deposit said pyrolytic material on said fibers and bond together said fibers to form a bonded body, (c) subsequently impregnating said bonded body with a carbonizable filler material, and, (d) curing and subsequently carbonizing said filler material within said bonded body.
Claim 12
Independent Claim
78 words
A method of producing fiber reinforced carbon articles by: (a) forming a fibrous carbon material into a shape without the use of a binder material, (b) infiltrating said fibers with a pyrolytic material in a manner to deposit said pyrolytic material on said fibers and bond together said fibers to form a bonded body, (c) subsequently impregnating said bonded body with a carbonizable filler material, and, (d) curing and subsequently carbonizing said filler material within said bonded body.
Claim 13
Dependent Claim
29 words
The method of claim 10 wherein the pyrolytic material is a product of the vapor deposition of a gas selected from the group of methane, ethane, butane and propane.
Claim 14
Dependent Claim
18 words
The method of claim 10 wherein steps (c) and (d) are repeated to produce a substantially solid product.
Claim 15
Dependent Claim
11 words
The method of claim 10 wherein the pyrolytic material is carbon.
Claim 16
Dependent Claim
