Özet:

In the aviation world, recently, thermoplastic materials have started to replace thermosets with their important advantages such as being both rapidly processable and recyclable. Graphene, on the other hand, has an important place in composite studies as it is the strongest nanomaterial. In this study, thermoplastic nanocomposites were produced by using graphene nanoplatelets (GNP) and poly(ether ether ketone) (PEEK) from thermoplastic material class. The solvent exchange method was chosen as the production method, and the composite of pure PEEK material could be produced first time with the solvent chosen, without adding any group to the PEEK chain structure. It was observed that the obtained composites were in granular foam structure and it was found that this structure caused a small decrease in the thermal decomposition temperature and glass transition temperature of the material. With the addition of graphene to the structure, the thermal properties of the material were maintained. With the obtained composite material, raw materials can be supplied to production benches such as injection molding and compression molding with an easy method without the need for melt blending devices which requires high temperature processing.
