The present invention relates to a method for manufacturing a window frame in which a glass is installed inside and a window frame which is manufactured into one-piece according to the method. The above method comprises: a) a step of covering a frame shaped tube member with a braided fabric or a multi-axial warp knitted fabric in order to have a thickness corresponding to the shape of a longitudinal section of the window frame; b) a step of forming a window frame preform by making the tube member, which is covered by the braided fabric or the multi-axial warp knitted fabric, into a shape corresponding to the window frame; and c) a step of hardening by filling resin into the window frame preform. According to the manufacturing method of the present invention, the window frame can be easily formed into one-piece without a surface only made with resins by covering the frame shaped tube member with the braided fabric or the multi-axial warp knitted fabric in order to have a thickness corresponding to the shape of longitudinal section of the window frame and emitting gas for shrinkage and making the member into the shape corresponding to the window frame. The window frame manufactured by the above method not only is light weighted but has enhanced physical properties such as toughness, fatigue resistance, and impact resistance and the likes so that operating expanses of vehicles, flights and the likes can be reduced and users can elastically prepare for development trends of the vehicles, flights and the likes whose main bodies are formed with composite materials.
