单向带预浸料在不可展曲面上铺贴变形的研究

Study on the Deformation of the Unidirectional Prepreg Overlay on an Undevelopable Surface

针对单向带预浸料在不可展曲面上铺贴过程中其变形量超过一定程度会产生铺贴缺陷的现象,采用变形角度表征变形量,设计了测量变形角度的试验方法,研究了变形角度与铺贴缺陷的关系,定义了变形角度警告值与限制值,通过设计正交试验测定了变形角度警告值与限制值,并确定了其影响因素,为单向带预浸料铺贴复杂型面的可制造性分析奠定了基础。

The excessive overlaying defor-mation will bring on defects, When the unidirectional prcprcg overlay on an undevelopable surface, character-ize the deformation using the deibrmation angle, design experiment method for measuring the deformation angle, study the relationship between the deformation angle and defects, define the warn value of deformation angle and the limit value of deformation angle, and find influencing factors for analyzing the producibility of the unidirectional prepreg overlaying on a complex surface.
