“…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.…”

The purpose of this paper is to study the effects of different trajectory planning methods on the mechanical properties of components. The scope of the research includes finite element simulation calculation and experimental tests of the actual structure. The test shall be carried out in the whole load range until the failure of the structure occurs. Taking the composite conical shell as an example, a variable angle initial path generation method of the conical shell surface is proposed, and the parallel offset algorithms based on partition and the circumferential averaging are proposed to fill the surface. Then, finite element analysis is carried out for the paths that satisfy the manufacturability requirements, the analysis results show that the maximum deformation and maximum transverse as well as longitudinal stress of fiber of circumferential averaging variable angle path conical shell are reduced by 16.3%, 5.85%, and 19.76%, respectively, of that of the partition variable angle path. Finally, the strength analysis of conical shells manufactured by different trajectory design schemes is carried out through finite element analysis and actual failure tests. The finite element analysis results are in good agreement with the experimental results of the actual structure. The results show that the circumferential uniform variable angle has good quality, and it is proved that the path planning algorithm that coordinates path planning and defect suppression plays an important role in optimizing placement trajectory and improving mechanical properties of parts.
