Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
132 words
A method for fabricating three-dimensional material comprising: a. orienting a group of filaments parallel to a given axis, b. weaving into said oriented filaments a second group of filaments arranged in a planar course, said filaments being at an angle to said axis, c. weaving into said oriented filaments a third group arranged in a plane which is contiguous with the plane of said second group of filaments, said third group of filaments also being woven at an angle to said second group filaments, d. said filaments being sized and spaced relative to each other such that the filaments of each group are in close touching contact with the filaments of each other group and, e. alternating such second and third groups of filaments in such manner to form a three-dimensional structure.
Claim 2
Independent Claim
132 words
A method for fabricating three-dimensional material comprising: a. orienting a group of filaments parallel to a given axis, b. weaving into said oriented filaments a second group of filaments arranged in a planar course, said filaments being at an angle to said axis, c. weaving into said oriented filaments a third group arranged in a plane which is contiguous with the plane of said second group of filaments, said third group of filaments also being woven at an angle to said second group filaments, d. said filaments being sized and spaced relative to each other such that the filaments of each group are in close touching contact with the filaments of each other group and, e. alternating such second and third groups of filaments in such manner to form a three-dimensional structure.
Claim 3
Dependent Claim
20 words
A method as described in claim 1 where, in addition, the structure is impregnated with a cured plastic matrix substance.
Claim 4
Dependent Claim
27 words
A method as defined in claim 1 in which said oriented filaments and said filaments of said second and third groups are mutually orthogonal to one another.
Claim 5
Dependent Claim
27 words
A method as defined in claim 1 wherein said structure is compressed until it has a density of at least 30% of the density of the filaments.
Claim 6
Dependent Claim
27 words
A method as defined in claim 3 wherein said structure is compressed until it has a density of at least 30% of the density of the filaments.
Claim 7
Dependent Claim
132 words
A three-dimensional material comprising: a. a group of filaments oriented parallel to a given axis, b. a second group of filaments arranged in a planar course, said filaments being woven into said oriented filaments at an angle to said axis, c. a third group arranged in a plane which overlies and is contiguous with the plane of said second group of filaments, said third group filaments also being woven into said oriented filaments but at an angle to said second group filaments, d. all of said filaments being sized and spaced relative to each other such that the filaments of each group are in close touching contact with the filaments of each other group, and e. alternating such second and third groups of filaments in said manner to form a three-dimensional structure.
Claim 8
Dependent Claim
132 words
A three-dimensional material comprising: a. a group of filaments oriented parallel to a given axis, b. a second group of filaments arranged in a planar course, said filaments being woven into said oriented filaments at an angle to said axis, c. a third group arranged in a plane which overlies and is contiguous with the plane of said second group of filaments, said third group filaments also being woven into said oriented filaments but at an angle to said second group filaments, d. all of said filaments being sized and spaced relative to each other such that the filaments of each group are in close touching contact with the filaments of each other group, and e. alternating such second and third groups of filaments in said manner to form a three-dimensional structure.
Claim 9
Dependent Claim
21 words
A three-dimensional material as described in claim 6 where, in addition, the structure is impregnated with a cured plastic matrix substance.
Claim 10
Dependent Claim
27 words
A structure as defined in claim 6 in which said oriented filaments and said filaments of said second and third groups are mutually orthogonal to one another.
Claim 11
Dependent Claim
23 words
A structure as defined in claim 6 wherein said structure has a density of at least 30% of the density of the filaments.
Claim 12
Dependent Claim
23 words
A structure as defined in claim 8 wherein said structure has a density of at least 30% of the density of the filaments.
