Abstract

Disclosed is a method for manufacturing bio-composites, in which biodegradable poly(lactic acid) (PLA) fibers are mixed, optionally along with general-purpose polypropylene fibers, using a carding process, and compression molded into bio-composites which overcome the problems of the PLA bio-composites manufactured by injection molding, and the PLA bio-composites manufactured thereby.

Claims

exact text as granted — not AI-modified
1 . A method for manufacturing a bio-composite, comprising:
 mixing poly(lactic acid) (PLA) fibers as a base polymer with natural fibers functioning as a reinforcing material in a carding process to produce webs;   processing the webs under a predetermined pressure into a mat; and   compression molding the mat to a bio-composite plate.   
   
   
       2 . The method according to  claim 1 , wherein PLA fibers are used in combination with polypropylene fibers to give a web. 
   
   
       3 . The method according to  claim 1 , wherein the natural fibers are kenaf or jute fibers. 
   
   
       4 . A poly(lactic acid) bio-composite material, manufactured by the method of  claim 1 . 
   
   
       5 . The method according to  claim 2 , wherein the natural fibers are kenaf or jute fibers. 
   
   
       6 . A poly(lactic acid) bio-composite material, manufactured by the method of  claim 2 . 
   
   
       7 . A poly(lactic acid) bio-composite material, manufactured by the method of  claim 3 . 
   
   
       8 . A poly(lactic acid) bio-composite material, manufactured by the method of  claim 5 .
