二步法三维编织预制件单元体结构及其图形显示

Unit structure of two-step 3-D braided preform and the graphics display

二步法三维编织预制件具有规则的单元体结构 ,它由 5组轴纱和 4组走向不同的编织线组成 .文中讨论了二步法三维编织方形预制件的单元体结构 ,并通过构造数学算法 ,建立了可变换视点的几何单元体显示模型 ,从不同角度真实地显示了预制件单元体结构 .

There are regular units in the two-step 3-D braided preform.The unit consists of five axial yarns and four braider yarns in different directions.The structure of the two-step 3-D braided rectanglar preform is discussed.Through establishing mathematical methods,the unit geometric model is built according to different view points and the unit structure is displayed truly from different angles.
