Method for manufacturing plant nanofiber and composite material

Abstract

The invention provides a method for manufacturing plant nanofiber including: providing multiple plant fibers; pressing the multiple plant fibers into a fiber block; cutting the fiber block into multiple blocks; cutting the multiple blocks with a grinder to form multiple granules; and separating plant nanofibers from the multiple granules through an airflow sorting mechanism. The invention also provides a composite material. The method for manufacturing plant nanofiber allows the plant nanofibers to be roughly straight. The composite material has better mechanical strength because it has substantially straight plant nanofibers.
