Luggage formed by composite material and manufacturing method thereof

A method for manufacturing a luggage formed by composite material, comprising the steps of:

• A) using a vacuum molding method to make a thermoplastic sheet into a shell, said shell comprising an outer surface, an inner surface, a receiving area surrounded by said inner surface, and a corner;
• B) providing a heating mold, said heating mold comprising an inner cavity mold area and then placing said shell in said inner cavity mold area to correspond said outer surface of said shell to an inner wall surface of said inner cavity mold area;
• C) providing a thermosetting carbon fiber plastic layer, said thermosetting carbon fiber plastic layer comprising an outer surface and an inner surface, and then arranging the outer surface of said thermosetting carbon fiber plastic layer on the inner surface of said shell;
• D) providing a reinforcing layer and setting said reinforcing layer on the inner surface of said thermosetting carbon fiber plastic layer at the location corresponding to said corner of said shell;
• and
• E) placing an airbag in said receiving area of said shell and inflate said airbag to support the inner surface of said thermosetting carbon fiber plastic layer and said reinforcing layer, and at the same time heating said heating mold to heat said shell, said thermosetting carbon fiber plastic layer and said reinforcing layer in said inner cavity mold area, so that said shell, said thermosetting carbon fiber plastic layer and said reinforcing layer are combined with each other,
• wherein said reinforcing layer is a metal layer;
• the method for manufacturing a luggage formed by composite material further comprising a steps of:
• providing another thermosetting carbon fiber plastic layer, placing the said another thermosetting carbon fiber plastic layer on the inner surface of said thermosetting carbon fiber plastic layer and said metal layer, inflating said airbag to support the said another thermosetting carbon fiber plastic layer, and heating said heating mold to heat said shell, said two thermosetting carbon fiber plastic layers and said metal layer, so that said shell and said two thermosetting carbon fiber plastic layers are combined with each other and said metal layer is wrapped in between said two thermosetting carbon fiber plastic layers.
