Abstract: Fiber-reinforced composite laminate structures employed in aerospace applications can utilize both woven and unidirectional lamina. While the woven lamina allow for a higher degree of damage tolerance, unidirectional lamina allow for higher stiffness. The utilization of these two lamina types in a hybrid architecture allows the laminate to have high stiffness while also possessing higher damage tolerance. Although these structurally hybridized laminates perform well, other hybrid architectures may offer an improvement of impact and/or compression-after-impact properties, and may lead to easier automation compared to hand-layup architectures used for current hybrid constructions. An intermediary architecture of woven laminates and unidirectional laminates, coined as pseudo-woven laminates, is proposed as an alternative hybridized structure. Pseudo-woven laminates make use of an in situ Automated Fiber Placement (AFP) manufacturing process to produce a unique pseudo-woven architecture. In this study, pseudo-woven laminates are hybridized with unidirectional laminates in an attempt to enhance impact and damage tolerance. Traditional and two different pseudo-woven hybrid laminates were manufactured using carbon fiber reinforced epoxy slit tapes. Laminates are subjected to low velocity drop impact loads to compare their damage tolerance and impact resistance characteristics.
