PLACEMENT MANUFACTURABILITY OF FIBER STEER TRAJECTORY PLANNING FOR COMPOSITE FLAT
摘要
Abstract
In order to explore trajectory planning for flat fiber steer and the placement manufacturability, this paper discussed a numerical method to obtain the path point of placement with straight line instead of curve. By analyzing deformation mechanism of prepreg tow, a new evaluation criterion for placement manufacturability based on the curvature radius of steer trajectory was proposed. And a paramatic study was conducted to investigate the effect of flat length in 90 degree direction, layup angle and angle interval on fiber steer curvature radius. The results show that the trajectory curvature radius of fiber steer is increased with the layup angle when the flat length in 90 degree direction and layup angle interval are fixed. On condition that flat 90 degree direction length is fixed, the trajectory curvature radius of fiber steer is decreased with the layup angle interval. When layup angle interval is fixed, the trajectory curvature radius of fiber steer is increased with the fiat 90 degree direction length.关键词
