Luggage with composite material integrally formed frame and manufacturing method thereof

A luggage made by a method for manufacturing a luggage with composite material integrally formed frame,

• the method comprising the steps of:
• A) using a vacuum molding method to make a thermoplastic sheet into a shell, said shell comprising a shell body, a shell edge disposed on an outer edge of said shell body and an accommodation area surrounded by said shell body and said shell edge;
• B) providing a heating mold, said heating mold comprising an inner concave mold area, a frame mold area and an inner wall surface, said frame mold area being located at an outer edge of said inner concave mold area, then placing said shell body in said inner concave mold area to set said shell edge in said frame mold area and to correspond an outer surface of said shell to said inner wall surface of said heating mold;
• C) providing a thermoset carbon fiber plastic layer, and setting an outer surface of said thermoset carbon fiber plastic layer on an opposing inner surface of said shell;
• D) providing a filling layer, and attaching said filling layer to an opposing inner surface of said thermoset carbon fiber plastic layer within said frame mold area;
• and
• E) setting an air bag in said accommodation area of said shell, and then expanding said air bag to the inner surface of said thermoset carbon fiber plastic layer and said filling layer, and then operating a heating mold to heat said shell body and said thermoset carbon fiber plastic layer in said inner concave mold area and said thermoset carbon fiber plastic layer and said filling layer in said frame mold area, so that said shell, said thermoset carbon fiber plastic layer and said filling layer are combined with each other,
• The luggage comprising:
• a first shell;
• a second shell openably assembled to said first shell;
• a first frame integrally formed with said first shell and located on an outer edge of said first shell;
• and
• a second frame integrally formed with said second shell and located on an outer edge of said second shell, so that when said first shell and said second shell are closed, said second frame is engaged in said first frame.
