Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
38 words
An armor laminate structure comprising a resin matrix with oppositely disposed front and rear surfaces and containing a filler of metal abrading particulate material and flexible woven ballistic fabric in supported engagement within the matrix and particulate material.
Claim 2
Dependent Claim
38 words
An armor laminate structure comprising a resin matrix with oppositely disposed front and rear surfaces and containing a filler of metal abrading particulate material and flexible woven ballistic fabric in supported engagement within the matrix and particulate material.
Claim 3
Dependent Claim
25 words
The armor laminate set forth in claim 1 including a single layer of ballistic fabric in spaced relationship between the said front and rear surfaces.
Claim 4
Dependent Claim
26 words
The armor laminate set forth in claim 1 including a plurality of layers of ballistic fabric in spaced relationship between the said front and rear surfaces.
Claim 5
Dependent Claim
78 words
The armor laminate set forth in claim 3 wherein certain layers of ballistic fabric are established of different yarn and of different weave and have different ballistic characteristics than certain of the other layers of ballistic fabric and wherein different ballistic fabrics are in predetermined sequential arrangement within the matrix and between the front and rear surfaces thereof whereby different layers of fabric work upon projectiles moved into contact with and entering the structure in predetermined sequential order.
Claim 6
Dependent Claim
97 words
The armor laminate set forth in claim 3 wherein the particulate metal abrading material in the matrix adjacent and related to certain layers of ballistic fabric is of different hardness, strength and size and has different metal abrading characteristics than the particulate metal abrading material adjacent and related to certain of the other layers of ballistic fabric and wherein said different metal abrading materials are arranged in predetermined sequence within the structure between the front and rear surfaces of the matrix whereby the different particulate materials work upon projectiles engaging and entering the structure in predetermined sequence.
Claim 7
Dependent Claim
97 words
The armor laminate set forth in claim 4 wherein the particulate metal abrading material in the matrix adjacent and related to certain layers of ballistic fabric is of different hardness, strength and size and has different metal abrading characteristics than the particulate metal abrading material adjacent and related to certain of the other layers of ballistic fabric and wherein said different metal abrading materials are arranged in predetermined sequence within the structure between the front and rear surfaces of the matrix whereby the different particulate materials work upon projectiles engaging and entering the structure in predetermined sequence.
Claim 8
Dependent Claim
47 words
The armor laminate set forth in claim 1 wherein the metal abrading particulate material is a hard brittle material in the form of substantially ovoid shaped particles which break into irregularly shaped fragments with metal abrading corners and edges under the impact forces of projectiles directed thereon.
Claim 9
Dependent Claim
14 words
The armor laminate set forth in claim 7 wherein the resin matrix is flexible.
Claim 10
Dependent Claim
16 words
The armor laminate set forth in claim 7 wherein the resin matrix is non-flexible and frangible.

Claim 20
Dependent Claim
101 words
The armor laminate set forth in claim 16 wherein the particulate metal abrading material in the matrix adjacent and related to certain layers of ballistic fabric in certain laminates is of different hardness, strength and size and has different metal abrading characteristics than the particulate metal abrading material adjacent and related to certain of the other layers of ballistic fabric and wherein said different metal abrading materials are arranged in predetermined sequence within the laminate structure between the front and rear surfaces of the matrix whereby the different particulate materials work upon projectiles engaging and entering the structure in predetermined sequence.
Claim 21
Dependent Claim
79 words
The armor set forth in claim 18 wherein certain layers of fabric of each laminate are established of different yarn and of different weave and have different ballistic characteristics than certain of the other layers of ballistic fabric and wherein different ballistic fabrics are in predetermined sequential arrangement within the matrix and between the front and rear surfaces thereof whereby different layers of fabric work upon projectiles moved into contact with and entering the structure in predetermined sequential order.
