Abstract

An energy absorber 10 which is made by a new and novel process and which includes beads, such as beads 12, 14 , and 16 which are selectively coupled together and reside upon an elastomeric surface 90 . The beads, such as beads 12, 14 , and 16 are formed, in one non-limiting embodiment, from a ceramic material and provide enhanced energy absorption characteristics which allows the created energy absorber 10 to be selectively “programmed” to be operatively deployed in a wide range of environments.

Claims

exact text as granted — not AI-modified
1 . A method for making an energy absorber comprising the steps of forming a mold having a certain absorber creation portion of a certain shape; providing a plurality of beads; providing resin; mixing said beads with said resin, effective to form a relatively thin layer of resin on said beads; placing the resin coated beads in said absorber creation portion of said mold; molding said contained resin coated beads, thereby forming said contained resin coated beads into said certain shape; and curing said molded beads, thereby forming said energy absorber.  
   
   
       2 . The method of  claim 1  further comprising the step of placing an elastomeric material into said absorber creation portion of said mold before placing said resin coated beads into said absorber creation portion.  
   
   
       3 . The method of  claim 2  wherein said beads comprise ceramic beads.  
   
   
       4 . The method of  claim 2  wherein said ceramic beads are coated with a polymer adhesive material.  
   
   
       5 . The method of  claim 3  wherein said ceramic beads are coated with a water based latex material.  
   
   
       6 . The method of  claim 3  wherein said ceramic beads are coated with a water based epoxy material.  
   
   
       7 . The method of  claim 3  wherein said ceramic beads are coated with a polyester material.  
   
   
       8 . The method of  claim 3  wherein said ceramic beads are each substantially spherical.  
   
   
       9 . The method of  claim 8  wherein said ceramic beads are each substantially identical.  
   
   
       10 . The method of  claim 9  wherein said plurality of coated beads cooperatively form a plurality of interstices.
