Automated fiber placement path generation method based on prospective analysis of path performance under multiple constraints

Numerical and Experiment Studies of Different Path Planning Methods on Mechanical Properties of Composite Components

“…Over the past decades, studies on AFP-based path planning were focused on initial path design and optimization [ 1 , 8 , 9 , 10 , 11 ], generation of offset path [ 10 , 11 ], and quality control [ 12 , 13 , 14 ]. Moreover, models of path deformation were also established to obtain the relationship between placement parameters and layup quality of fiber path [ 1 , 14 ].…”

“…Moreover, models of path deformation were also established to obtain the relationship between placement parameters and layup quality of fiber path [ 1 , 14 ]. Many studies for path generation for open-contoured structures were carried out by Shirinzadeh, Long Yan et al To sum up, the main construction methods of the initial reference path mainly include [ 15 , 16 , 17 , 18 ]: forming a fixed angle with an axis [ 10 ], along the direction of principal stress distribution or ply bearing information [ 19 ], surface–plane intersection strategy [ 20 ], projecting the reference line on the mold surface [ 21 ], etc. Shirinzadeh et al [ 11 ] proposed a novel path planning algorithm for open-contoured structures, the initial reference path is generated by projecting the major axis on the mold surface, the entire surface is then completely covered by continuously offsetting the initial reference path.…”

“…To overcome this limit, Duan [ 9 ] proposed an angle control algorithm of trajectory planning, and the algorithm has been successfully validated to plan the path of the airplane’s S-shaped inlet. Qu [ 10 ] also proposed a path generation method to overcome the contradiction between angle direction and fiber wrinkles on the S-shape inlet surface, and the proposed method can control the angle deviation within 10 degrees and meet the curvature requirements. However, there are still few studies on the effect of carbon fiber ply angle on the mechanical properties of resin matrix composites.…”
