The effect of laser-assisted automated tape placement (LATP) in-situ consolidation processing parameters on mechanical properties of manufactured laminates is an important consideration. In this study, a combination of placement rates and processing temperatures were assessed to determine their effects on wound laminated hoops for two carbon fibre (CF)/PEEK material systems, one with sized fibres and one without. It was found that these CF/PEEK material systems, while manufactured with the same LATP processing parameters, have different maximum interlaminar shear strengths, void growth characteristics and crystallinity levels. The results indicate that the placement rate has a statistically significant influence on the interlaminar shear strength and sample thickness. It was observed that there is a notable interaction between placement rate and processing temperature for the unsized fibre CF/PEEK system.
