Abstract: Outstanding mechanical and transport properties of carbon-based nanostructured materials, such as carbon nanofibers, graphene, and carbon nanotubes (CNTs) have been demonstrated but there are challenges incorporating the nanomaterials into manufacturing processes that are widely accepted. CNTs have high electrical and thermal conductivity which can be employed as heat spreaders and lighting strike protection potentials. These promising properties make materials such as these very desirable for transferring multifunctional performances into fiber-reinforced structural composites. Polyether ether ketone (PEEK) is a very highly machinable, organic, semi-crystalline thermoplastic. Its polymer structure yields exceptional environmental resistance, mechanical strength, and dimensional stability. CNT thin films were integrated into a PEEK carbon fiber prepreg as interplys to create a hybrid composite material with multifunctional properties. The compression molding method of manufacturing hybrid composite laminates was investigated to understand the integration of CNTs into a thermoplastic composite to increase the overall characteristics. Crystallization, thermomechanical, microscopy, and quality analysis of the hybrid samples were assessed to determine which state created the most desirable functions. Modeling and simulation of the interply hybrid composite were demonstrated to understand the stress states and for the future design of optimized nanomaterial structures. Manufacturing of PEEK/CNT hybrid composites shows good performance and potential for leaps in multifunctional performance for thermoplastic composites.
