Abstract


Polymer matrix composites can be used to design various aircraft components because of their strength-to-weight advantages and durability. However, the material must satisfy the necessary design allowable when implemented into a structural application. Tailor Fiber Placements is a process in which dry carbon fibers can be stitched into any fabric, impregnated with resin, and molded to any geometrical component. In our study, in-plane waviness was introduced to the material to enhance the fracture toughness of the laminated composite—a sinusoidal function defined by four different types of waviness. The overall objective is to develop a fracture tolerant material creating a tortuous path for damage to propagate, which could enhance impact resistance, susceptibility to extreme environments, and dissipative energy mechanisms.
