Buckling Performance Optimization of Steered Composite Panels While Accounting for Manufacturing Constraints

摘要

Automated Fiber Placement (AFP) technology has revolutionized manufacturing of composite structuresand is quickly replacing traditional hand-layup manufacturing. Among others, the notable advantage of AFPis that the designer is no more restricted to the use of straight ber paths, enabling optimizing for desiredstructural performance. The scope of this work is to identify the manufacturing parameters and associatedconstraints imposed by these parameters on the manufacturability of steered ber structural panels, referredto as the manufacturing signature (MS), using currently available AFP machines. This is demonstrated byan optimization problem to maximize the buckling load of a panel with steered bers. Further, deviationsof as- manufactured panels from the ideal pristine designs of these optimal solutions are discussed and aninvestigation on their eects on performance of the manufactured panel is presented.
