The invention relates to a method for producing a self-reinforced thermoplastic composite material including: providing strips of a thermoplastic and weaving the plastic strips into a base fabric. The plastic strips for this are produced by at least the following steps: producing pre-stretched fibres from a partially crystalline polyester homopolymer with a melting point by extrusion on at least one spinning nozzle and subsequent stretching and joining a plurality of pre-stretched endless fibres lying next to and/or above one another to a matrix of an amorphous polyester homopolymer at a processing temperature T2<T1, wherein the temperature difference between T1 and T2 is at least ΔT=30° C.

A piece of luggage may include a front side, a rear side, a top side, a bottom side, a right side and a left side that define an enclosed space. The enclosed space may be divided into one or more compartments. The luggage may further include at least one zipper to access the enclosed space. The at least one zipper may include a zipper track, at least one zipper slider, and at least on zipper tab. At least a portion of the zipper track may be positioned within one or more recessed areas defined by at least some of the sides of the luggage. In some embodiments, the zipper track may be positioned within the one or more recessed areas along substantially the entire length of the zipper track.

A method for manufacturing a luggage formed by composite material includes the steps: A) using a vacuum molding method to make a thermoplastic sheet into a shell; B) placing the shell in an inner cavity mold area of a heating mold to correspond the outer surface of the shell to the inner wall surface of the inner cavity mold area; C) setting the outer surface of the thermosetting carbon fiber plastic layer on the inner surface of the shell ; D) setting the reinforcing layer on the inner surface of the thermosetting carbon fiber plastic layer at the location corresponding to the corner of the shell; and E) placing an airbag in the receiving area of the shell and inflating the airbag to support the inner surface of the thermosetting carbon fiber plastic layer and the reinforcing layer.
