3D textile preforms are being used increasingly in the aerospace industry to provide enhanced properties and improve manufacturing time for composite components. With careful design, net-shaped preforms can be made which allow components such as fan blades to be constructed in one piece. These net-shaped components often have complex geometries which, in a 3D woven part, will necessitate the use of either varying weave patterns or one pattern which is gradually scaled to suit. These patterns do not necessarily scale in a straightforward manner and behaviour during compaction will change as the design is scaled. The inability to incorporate the effects of these changes in dimension into the design process is a major limitation which has been identified by manufacturers such as Rolls-Royce. This project will develop novel methods for modelling these complex components building functionality into the in-house geometric textile modelling software, TexGen (http://texgen.sourceforge.net).

3D 纺织预成型件越来越多地应用于航空航天工业，以增强复合材料部件的性能并缩短制造时间。通过精心设计，可以制造出网状预成型件，从而可以将风扇叶片等部件构建为一件。这些网状部件通常具有复杂的几何形状，在 3D 编织部件中，需要使用不同的编织图案或逐渐缩放以适应的一种图案。这些模式不一定以直接的方式缩放，压缩过程中的行为会随着设计的缩放而改变。无法将这些尺寸变化的影响纳入设计过程是一个主要限制，劳斯莱斯等制造商已经发现了这一点。该项目将开发新颖的方法，将这些复杂组件的功能构建到内部几何纺织建模软件 TexGen (http://texgen.sourceforge.net) 中。
