整体T形管道接头预型件的设计

Design of integrated composite T-joint preform

以T形管道接头预型件为例,讨论了其平面织造方法,计算了T形管道接头预型件在复合成型时的变形要求;并采用平行四边形法,分析了经纬纱密度等织物参数对织物变形能力的影响.这种平面织造方法也适用于其它多种接头织物的织造.

A plane weaving method has been discussed to produce T-joint preform. The fabric deformation in the composite molding is calculated. The deformation capability affected by the fabric parameters such as warp and weft yarn density is also analyzed based on the parallelogram method. This plane weaving method can be extended to produce other types of joint preforms.
