Abstract
Abstract A method for producing a composite of a water hardening substance and a fibrillated organic film network having its primary strength in one direction. A plurality of layers of expanded fibrillated organic film network are incorporated in a water hardening substance such that the primary strength directions of the layers are a ligned to form at least one mass of green material. The or each mass is then formed into a structure in which the primary strength direction of the layers of expanded organic network extend in at least two directions. This structure may be a laminar structure formed by superimposing sheets of green material, or a helically folded structure.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
95 words
A method for producing a composite of a water-hardening substance and a fibrillated organic film network having its primary strength in one direction, the method comprising the steps of incorporating a plurality of layers of expanded fibrillated organic film network in a water-hardening substance such that the primary strength directions of the said layers are aligned to form at least one mass of green material, and forming the or each mass of green material into a structure in which primary strength directions of layers of expanded fibrillated organic network extend in at least two directions.
Claim 2
Independent Claim
95 words
A method for producing a composite of a water-hardening substance and a fibrillated organic film network having its primary strength in one direction, the method comprising the steps of incorporating a plurality of layers of expanded fibrillated organic film network in a water-hardening substance such that the primary strength directions of the said layers are aligned to form at least one mass of green material, and forming the or each mass of green material into a structure in which primary strength directions of layers of expanded fibrillated organic network extend in at least two directions.
Claim 3
Dependent Claim
28 words
A method according to claim 1, wherein the primary strength directions of the layers of expanded fibrillated organic network extend in two mutually perpendicular directions in the structure.
Claim 4
Dependent Claim
30 words
A method according to claim 1 or claim 2, wherein the said structure is formed by superimposing two or more said masses of green material to form a laminar structure.
Claim 5
Dependent Claim
39 words
A method according to claim 3, wherein the primary strength direction of layers of expanded fibrillated organic network in one lamina extend perpendicularly to the primary strength direction of layers of expanded fibrillated organic network in each adjacent lamina.
Claim 6
Dependent Claim
19 words
A method according to claim 1, wherein the said structure is formed by folding one mass of green material.
Claim 7
Dependent Claim
30 words
A method according to claim 5, wherein the mass of green material is in the form of a sheet, the sheet being folded into a helical arrangement and compressed laterally.
Claim 8
Independent Claim
93 words
A method for producing a composite of a water-hardening substance and fibrillated organic film network having its primary strength in one direction, the method comprising forming two or more sheets of green material by incorporating a plurality of layers of expanded fibrillated organic film network into a mass of water-hardening substance, applying two sheets to one another such that the primary strength direction of the layers in one sheet extend perpendicularly to the primary strength directions of layers in the other sheet, and curing the green material to form a bonded laminar composite.
Claim 9
Independent Claim
93 words
A method for producing a composite of a water-hardening substance and fibrillated organic film network having its primary strength in one direction, the method comprising forming two or more sheets of green material by incorporating a plurality of layers of expanded fibrillated organic film network into a mass of water-hardening substance, applying two sheets to one another such that the primary strength direction of the layers in one sheet extend perpendicularly to the primary strength directions of layers in the other sheet, and curing the green material to form a bonded laminar composite.
Claim 10
Dependent Claim
18 words
