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-modified1 . 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 .Join the waitlist — get patent alerts
