A complicated question which structure analysis in Three-Dimension braided composites is solved By modeling computer graphics

then the composites mechanics performance will be expediently analysed. This paper presents a quantificationally descriptive method of complicated fabric structure in Three-Dimension braided composites for the prevalent braided technology-four-step procedure. By emulating the spatial location of optional yarn as computer Three-Dimension model

the yarn trend in Three-Dimension braided composites is shown conveniently and clearly

and every yarn can be separated and dissected for observing relative position by simply operating the completed model. Some presented conclusions of geometrical description are also validated.
