Abstract

A damped abrasive article comprises a damping body and an abrasive surface provided on at least a portion of the damping body. The damping body comprises a synthetic polymer having a Storage Modulus from 1000 MPa to 2500 MPa and a Loss factor from 0.025 to 0.10 at 25° C. and 10 Hz.

Claims

exact text as granted — not AI-modified
1 . A damped abrasive article comprising:
 a damping body; and   an abrasive surface provided on at least a portion of the damping body;   wherein the damping body comprises a synthetic polymer having a Storage Modulus from 1000 MPa to 2500 MPa and a Loss factor from 0.025 to 0.10 at 25° C. and 10 Hz.   
     
     
         2 . The damped abrasive article of  claim 1  wherein the damping body comprises polyamide 6. 
     
     
         3 . The damped abrasive article of  claim 1  wherein the damping body comprises polyamide 6 and glass fibers. 
     
     
         4 . The damped abrasive article of  claim 3  wherein the glass fibers comprise from 1 to 50 percent by weight of the damping body. 
     
     
         5 . The damped abrasive article of  claim 3  wherein the glass fibers comprise 30 percent by weight of the damping body. 
     
     
         6 . The damped abrasive article of  claim 1  wherein the machine attaching end and the damping body comprise a synthetic polymer having a Storage Modulus from 1000 MPa to 2500 MPa and a Loss factor from 0.025 to 0.10 at 25° C. and 10 Hz. 
     
     
         7 . The damped abrasive article of  claim 1  wherein the Storage Modulus obtained at 25° C. and 10 Hz is greater than the Storage Modulus obtained at 45° C. and 10 Hz for the damping body. 
     
     
         8 . The damped abrasive article of  claim 2  wherein the Storage Modulus obtained at 25° C. and 10 Hz is greater than the Storage Modulus obtained at 45° C. and 10 Hz for the damping body. 
     
     
         9 . The damped abrasive article of  claim 3  wherein the Storage Modulus obtained at 25° C. and 10 Hz is greater than the Storage Modulus obtained at 45° C. and 10 Hz for the damping body. 
     
     
         10 . The damped abrasive article of  claim 4  wherein the Storage Modulus obtained at 25° C. and 10 Hz is greater than the Storage Modulus obtained at 45° C. and 10 Hz for the damping body. 
     
     
         11 . The damped abrasive article of  claim 5  wherein the Storage Modulus obtained at 25° C. and 10 Hz is greater than the Storage Modulus obtained at 45° C. and 10 Hz for the damping body. 
     
     
         12 . The damped abrasive article of  claim 6  wherein the Storage Modulus obtained at 25° C. and 10 Hz is greater than the Storage Modulus obtained at 45° C. and 10 Hz for the damping body.
