Vibration dampening material and method of making same

Abstract

The present invention is directed to a material adapted to reduce vibration and, more specifically, to a material adapted to dissipate and evenly distribute transmitted vibrations. The material is particularly suited for impact and/or heavy load vibration resistance.

1 . A vibration-reducing material comprising: 
 a foam material layer;    an aramid material layer that distributes vibration to facilitate vibration dampening; and    a elastomeric material layer configured to absorb vibration.    
   
   
       2 . The vibration-reducing material of  claim 1 , wherein the second aramid layer is located between the foam material layer and the elastomeric layer.  
   
   
       3 . The vibration-reducing material of  claim 1 , wherein the foam material layer is substantially rigid.  
   
   
       4 . The vibration-reducing material of  claim 3 , wherein areas of predetermined weakness are formed in the foam layer to allow the vibration-reducing material to flex along such areas of predetermined weakness.  
   
   
       5 . The vibration-reducing material of  claim 3 , wherein the areas of predetermined weakness are formed by making cuts in the foam layer.  
   
   
       6 . The vibration-reducing material of  claim 3 , wherein the areas of predetermined weakness are formed by compressing portions of the foam layer.  
   
   
       7 . The vibration-reducing material of  claim 3 , wherein the areas of predetermined weakness are formed by removing portions of the foam layer.  
   
   
       8 . The vibration-reducing material of  claim 3 , wherein the areas of predetermined weakness are formed at areas of the foam layer that are thinner than other areas of the foam layer.  
   
   
       9 . The vibration-reducing material of  claim 3 , wherein the areas of predetermined weakness comprised parallel grooves.  
   
   
       10 . The vibration-reducing material of  claim 3 , wherein the areas of predetermined weakness comprise groves that form polygon shapes.  
   
   
       11 . The vibration-reducing material of  claim 3 , wherein the polygon shapes are selected from the group consisting of: hexagons, diamonds, octagons, circles, ellipses, and combinations thereof.  
   
   
       12 . The vibration-reducing material of  claim 3 , used as a protective pad.  
   
   
       13 . The vibration-reducing material of  claim 3 , used as a protective pad to dissipate vibration from an impact and impact energy.  
   
   
       14 . The vibration-reducing material of  claim 1 , wherein the foam material layer is substantially flexible.  
   
   
       15 . A vibration-reducing material comprising: 
 an aramid material layer, wherein the aramid material layer distributes vibration to facilitate vibration dampening, and contains and stabilizes an elastomeric layer located adjacent to the aramid material layer.    
   
   
       16 . A vibration-reducing material comprising: 
 a foam material layer;    a high tensile strength material layer that distributes vibration to facilitate vibration dampening; and    a elastomeric material layer configured to absorb vibration.    
   
   
       17 . A vibration-reducing material comprising: 
 a high tensile strength material layer, wherein the high tensile strength material layer distributes vibration to facilitate vibration dampening, and contains and stabilizes an elastomeric layer located adjacent to the high tensile strength material layer.
