大型复合材料筒形结构自动铺带技术

采用国产T300/605热熔法预浸料,对大型复合材料筒形结构自动铺带技术进行了研究.通过对自动铺带角度的工艺优化,铺带角度进行微调,实现了复合材料筒形结构的满覆盖铺放.在此基础上进行了大型复合材料筒形结构的自动铺带工艺试验,对自动铺带工艺试验件进行无损检测及取样性能测试.结果表明:预浸料铺覆性良好,自动铺带成型的预浸带间隙或重叠≤1 mm,铺带角度与理论铺带角度偏差≤0.2°.试验件成型质量良好,自动铺带技术可以满足大型复合材料结构高质量成型需求.

Automated Tape Placement in Large Composite Cylinder Structure

Automated tape placement in large cylinder structure was studied with domestic T300/605 melting prepared prepreg.The ply angle was optimized to achieve the full-scale laying in large cylinder structure,which would avoid the gap or overlaps.On the basis of the optimization,the process experiment of large cylinder structure with automated tape placement was carried out and the result indicated that the adhesion of the prepreg tape was fit for automated tape placement.The gap or overlap between the tapes were ...
