Polymer Composite Material

Abstract

The present invention relates to a polymer composite having a multi-layered structure formed by implanting one or more steels and fibers into a polymer and adhering the one or more steels and fibers to the polymer and thus being lightweight and having high strength, high toughness, and high wear resistance. The polymer composite includes a polymer, a filament implanted into the polymer and adhered to the polymer, and a fiber implanted into the polymer and adhered to the polymer, in which either only the filament or the fiber is implanted into the polymer and adhered to the polymer, or the filament and the fiber are simultaneously implanted into the polymer and adhered to the polymer.

1 . A polymer composite comprising: a polymer; a filament implanted into the polymer and adhered to the polymer; and a fiber implanted into the polymer and adhered to the polymer,
 wherein either only the filament or the fiber is implanted into the polymer and adhered to the polymer, or   the filament and the fiber are simultaneously implanted into the polymer and adhered to the polymer.   
     
     
         2 . The polymer composite of  claim 1 , wherein the filament comprises at least one steel or fiber. 
     
     
         3 . The polymer composite of  claim 1 , wherein the polymer is adhesion-treated with an adhesive and adhered to the filament or the fiber. 
     
     
         4 . The polymer composite of  claim 1 , wherein the filament or the fiber is surface-modified with plasma and adhered to the polymer. 
     
     
         5 . The polymer composite of  claim 1 , wherein the polymer and the filament or the polymer and the fiber have an adhesion force ratio of 5% or more. 
     
     
         6 . The polymer composite of  claim 1 , wherein an adhesion interface formed between the polymer and the filament or between the polymer and the fiber has a void ratio of 90% or less. 
     
     
         7 . The polymer composite of  claim 1 , wherein the filament is positioned at a center of the polymer, and the fiber is positioned around the filament. 
     
     
         8 . The polymer composite of  claim 7 , wherein the fiber comprises a plurality of fibers that form a fiber layer around the filament,
 wherein the fiber layer is formed as at least one layer.   
     
     
         9 . The polymer composite of  claim 7 , further comprising a filler implanted into the polymer and adhered to the polymer,
 wherein the filler comprises a steel or a fiber.   
     
     
         10 . The polymer composite of  claim 1 , wherein the filament and the fiber are implanted into the polymer in at least one form selected from a linear form, a twisted pair form, and a fabric form. 
     
     
         11 . The polymer composite of  claim 1 , wherein the polymer comprises at least one selected from thermoplastic polyurethane (TPU), high density polyethylene (HDPE), polyethylene (PE), polypropylene (PP), and polyester, and
 the fiber comprises at least one selected from aramid, polyester, nylon, and PE.   
     
     
         12 . The polymer composite of  claim 1 , wherein the polymer composite has any one of circular, rectangular, plate, and sheet cross-sectional shapes. 
     
     
         13 . The polymer composite of  claim 1 , wherein the polymer is rapidly cooled at a high pressure, thus resulting in a polymer internal void area ratio of 2% or less. 
     
     
         14 . The polymer composite of  claim 1 , wherein the polymer comprises HDPE and HDPE-g-MAH as an additive.
