Abstract: This paper introduces a geometric modeling method for braids structure with polygon prism based on the intersection of helical surface and braiding surface. Two kinds of surfaces are abstracted by the decomposition and re-composition of strand motions which include all braiding information. Based on this fact, the modeling method is developed based on the intersection of helical surface and braiding surface and the detailed modeling process is introduced by SolidWorks^ 2013.

Key words: polygon prism, braided structures, intersection of surfaces, composites
