“…Therefore, drawing on the biological experience, we developed the helicoidal architecture to build a laminated carbon-fiber epoxy-matrix composite. However, since interlaminar strength is still governed by the matrix material, the delamination 8 resistance must be increased by using through-thickness reinforcement (Barrett, 1996;Rugg et al, 1998Rugg et al, , 2002Mouritz et al, 1997aMouritz et al, , 1999; these reinforcements increase the load capacity, and prevent initiation and propagation of delamination cracks. The z-stapling reinforcement with an appropriate pattern was evaluated and implemented in this work as described in detail later in this report.…”
