Abstract: While automated fiber placement (AFP) is a standard aerospace composite manufacturing process, adoption and adaptation of these technologies have been slower for cost and rate sensitive applications and industries, such as marine and automotive. Reducing or eliminating large capital investment requirements such as ovens and autoclaves may make AFP a more approachable option for a wider range of industries, especially if suitable mechanical properties can be achieved at high deposition speeds to reduce manufacturing times for large structures. In-situ consolidation of thermoplastic laminates allows for the elimination of expensive and time-consuming post-processing steps, such as autoclave or vacuum-assisted oven consolidation, often required for aerospace applications. In this study, a carbon fiber/ LM-PAEK™ thermoplastic laminate was manufactured at four different deposition rates ranging from 0.085-0.847m/s using robotic 8-lane laser-based thermoplastic AFP equipment, then subsequently tested to determine the effect of deposition rates on mechanical properties. Tensile and compressive properties are presented and discussed as a function of deposition speeds.
