Abstract
Abstract A damped laminated metal structure includes a first sheet of material defining a first surface, a second sheet of material defining a second surface, a bonding material extending between the first surface and the second surface to bond the first sheet of material to the second sheet of material, and a plurality of reinforcements disposed in the bonding material between the first surface and the second surface to reduce effects of creep to a minimal extent and increase torque retention capabilities of the damped laminated metal structure.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
88 words
A damped laminated metal structure comprising: a first sheet of material defining a first surface; a second sheet of material defining a second surface; a bonding material extending between said first surface and said second surface to bond said first sheet of material to said second sheet of material; and a plurality of reinforcements disposed in said bonding material and between said first surface and said second surface to reduce effects of creep to a minimal extent and increase torque retention capabilities of said damped laminated metal structure.
Claim 2
Dependent Claim
36 words
A damped laminated metal structure as set forth in claim 1, wherein said reinforcements are fabricated from a hard material having a stiffness and density greater than a predetermined stiffness and density of said bonding material.
Claim 3
Dependent Claim
24 words
A damped laminated metal structure as set forth in claim 1 or claim 2, wherein said reinforcements are fabricated from a high density material.
Claim 4
Dependent Claim
56 words
A damped laminated metal structure as set forth in any of claims 1 to 3, wherein each of said reinforcements comprises a respective outer surface including a first flat end and a second flat end, said first flat end abutting said first sheet of material and said second flat end abutting said second sheet of material.
Claim 5
Dependent Claim
23 words
A damped laminated metal structure as set forth in any preceding claim, wherein said first sheet of material is fabricated from a metal.
Claim 6
Dependent Claim
34 words
A damped laminated metal structure as set forth in any preceding claim, wherein said second sheet of material is fabricated from a metal; and/or wherein said bonding material is fabricated from a viscoelastic material.
Claim 7
Dependent Claim
39 words
A damped laminated metal structure as set forth in any preceding claim, wherein said reinforcements comprise a plurality of metal spheres disposed between said first surface and said second surface to maintain a predetermined spacing for said bonding material.
Claim 8
Dependent Claim
145 words
A damped laminated metal structure comprising: a first sheet of metal defining a first surface; a second sheet of metal defining a second surface; a viscoelastic material extending between said first surface and said second surface to bond said first sheet of metal to said second sheet of metal in spaced relation thereto, said viscoelastic material having a uniform predefined thickness and a predetermined viscoelasticity; and a plurality of metal spheres disposed in said viscoelastic material between said first surface and said second surface, said metal spheres extending across said uniform predefined thickness and having a first flat end abutting said first surface and a second flat end abutting said second surface such that said metal spheres maintain a predetermined spacing for said viscoelastic material to reduce effects of creep to a minimal extent and increase torque retention capabilities of said metal laminate damping structure.
Claim 9
Independent Claim
70 words
A method for fabricating a damped laminated metal structure, the method comprising the steps of: forming a first sheet of material to a predetermined configuration; forming a second sheet of material to the predetermined configuration; adding reinforcements to a bonding material in a liquid form and curing the bonding material to form a bonding layer; and laminating the first sheet of material, bonding layer and second sheet of material together.
Claim 10
Dependent Claim
56 words
A method as set forth in claim 9, including the step of creating a first flat end and a second flat end on each of the reinforcements, preferably by means of a step of applying a force to the first and second sheets of material to create the first and second flat ends on the reinforcements.
