Abstract: The introduction of reinforced thermoplastic composites for large aerospace structural applications has been a developmental effort, as the benefits they offer have been overshadowed by the knowledge base built around more established thermoset composites. Thermoset composites require a long curing process that cannot be reversed, while thermoplastic composites can be rapidly processed and reshaped multiple times without significantly degrading the material and its properties. They also offer superior toughness and resistance to environmental factors. However, the quality and processability of unidirectional prepreg material is not well understood.This paper presents research studies conducted on two different thermoplastic materials. Materials were examined for their physical and thermal-mechanical qualities as well as consolidated laminate properties. The goals of this research are to understand laminate quality and processability of two out of autoclave (OoA) processes: oven consolidation and stamp forming. Autoclave consolidation provides a reliable baseline dataset; a comparative understanding of the materials can be obtained by comparing OoA results to autoclave results. OoA processing significantly reduces cost and time factors and enables high-rate manufacturing of composites. Industry can utilize the set of specific processing parameters provided in this paper as a guideline for novel, sustainable and efficient high-rate manufacturing techniques in hopes of assisting the current and future requirements for aerospace industry.
