Abstract
Abstract Bullet proof armor comprising a laminated pad with front and rear surfaces and composed of a plurality of loosely related fabric sheets woven of fibres having high tensile strength, said fibres of the fabric adopted to establish gripping and holding engagement on the surface of bullets directed toward and impinging of said front surface and advancing into the pad, and metal abrading means comprising metal abrading particulate material at said front surface and adapted to abrade and condition the surface of bullets whereby the fibres of the fabric can better grip and hold onto the bullets.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
89 words
A bullet proof armor panel structure including a pad comprising a multiplicity of normally flat sheets of fabric in loosely related surface to surface relationship, said pad having front and rear surfaces, and a flat metal abrading means with front and rear surfaces arranged with its rear surface opposing the front surface of the pad, said abrading means including a mass of hard metal abrading particulate material arranged with its particles in substantial bridging contact with each other and binding means normally maintaining the particles in substantial fixed position.
Claim 2
Dependent Claim
89 words
A bullet proof armor panel structure including a pad comprising a multiplicity of normally flat sheets of fabric in loosely related surface to surface relationship, said pad having front and rear surfaces, and a flat metal abrading means with front and rear surfaces arranged with its rear surface opposing the front surface of the pad, said abrading means including a mass of hard metal abrading particulate material arranged with its particles in substantial bridging contact with each other and binding means normally maintaining the particles in substantial fixed position.
Claim 3
Dependent Claim
45 words
The armor panel structure set forth in claim 1 wherein said sheets of fabric are flexible and pliable, said pad is flexible and pliable and said binding means maintaining the particulate matter in substantial fixed position is flexible, whereby the armor panel structure is flexible.
Claim 4
Dependent Claim
42 words
The armor panel structure set forth in claim 2 wherein the binding means includes a multiplicity of normally flat sheets of fabric in and about which said particulate material is deposited and a cement bonding those sheets and the particulate material together.
Claim 5
Dependent Claim
24 words
The armor panel structure set forth in claim 2 wherein the binding means includes a resin matrix in which the particulate material is set.
Claim 6
Dependent Claim
42 words
The armor panel structure set forth in claim 2 wherein the binding means includes a multiplicity of fabric sheets extending through the particulate material and a resin matrix in which the particulate material and the sheets of fabric related thereto are set.
Claim 7
Dependent Claim
42 words
The armor panel structure set forth in claim 1 wherein the binding means includes a multiplicity of normally flat sheets of fabric in and about which said particulate material is deposited and a cement binding those sheets and the particulate material together.
Claim 8
Dependent Claim
24 words
The armor panel structure set forth in claim 1 wherein the binding means includes a resin matrix in which the particulate material is set.
Claim 9
Dependent Claim
42 words
The armor panel structure set forth in claim 1 wherein the binding means includes a multiplicity of fabric sheets extending through the particulate material and a resin matrix in which the particulate material and the sheets of fabric related thereto are set.
Claim 10
Dependent Claim
24 words
The armor panel structure set forth in claim 1 which further includes an impact absorbing deformable liner adjacent the rear surface of the pad.
Claim 11
Dependent Claim
86 words
The armor panel structure set forth in claim 1 wherein the layer of particulate material is made up of a plurality of predetermined volumes of predetermined different sizes of particles which are such that the particles of each smaller size of particles occur within the voids and interstices established by the next larger size of particles and establish bridging supporting engagement with and between the next larger size of particles adjacent thereto when said next larger size of particles are in bridging contact with each other.
