Abstract
A method of manufacturing a natural composite material multilayer structure includes: manufacturing a felt layer; spraying a thermosetting resin onto one surface or both surfaces of the felt layer; forming an intermediate layer of the sprayed thermosetting resin to form a composite material; heat-pressing the composite material through a heated mold; and cold-pressing the heat-compressed composite material.
