“…By studying the failure modes of the composite stiffened panels under tensile loads [ 15 ], compressive loads [ 16 , 17 , 18 ], shear loads [ 19 , 20 , 21 ], and with preexisting delamination defects [ 22 , 23 , 24 ], it is possible to use these failure modes to guide process improvements. Furthermore, investigating the effects of different process steps [ 13 ], process parameters [ 25 , 26 ], and fabric ply angles [ 27 , 28 ] on the performance of the composite stiffened panels can provide insights for improving process methods, enhancing molding quality, and optimizing structural design.…”
