Abstract: It is well known that carbon fiber composite materials have obvious advantages
such as high specific strength, high specific stiffness, light weight, and integration of
structural functions compared with other metal materials. They have been used in civilian
products, automobiles, rail transportation, aerospace, and other different areas. Siemens
FiberSim software has an extremely important position in the field of composite material
design and processing, Pro modules can be used for layer design for some simple parts, Elite
modules can be used for partition layer design for some parts, such as in high-speed rail and
aerospace industries. This article describes the design method of the fan blades of aero-engine
based on the function of automatically generated layer using Volume Fill of FiberSim
software, to find out a set of design process for unequal thickness parts of curved surface, this
process can also be applied to other related structural parts with similar structure in different
industries.

1 引言
基于体积的铺层填充功能(Volume Fill Composite Part
Development)是FiberSim15.0版本开发出来的新功能,是一个非常强大的自动创建铺层
的设计模块,可以根据所选择零件的封闭曲面来自动生成铺层并进行填充,设计人员只
需在CAD三维软件内对模型进行前处理,提取出相关元素,即上表面、下表面(或中面)、
坐标系原点、坐标方向、设计及工艺边界,并确定所选用的材料,FiberSim便能够自动根
