We previously showed mechanism simulation techniques for basic flat braiding and basic cord braiding. In this paper, the simulation program of cord braiding has been developed as follows ; (1) the drawing-up speed of the mandrel is estimated to obtain the required braiding angle in the case of a circular cylinder composite. (2) in the tublar composites, with changing the cross section to the longitudinal direction, the drawing-up speed of the mandrel must be varied to obtain the same braiding angle according to the shapes of cross section. (3) the maximum braiding angle is predicted taking the width of the yarn into consideration.
