| Popis: | Fusion assembly is a highly promising technique to join thermoplas- tic to thermoset composites, enabling the use of both the most affordable com- posite material and process for each sub structure.Yet, some major challenges need to be pull through such as the functionalizing of the thermoset compos- ite surface by co-curing an appropriate thermoplastic interlayer or realizing a fast and robust welding process that fulfils all quality and mechanical require- ments. In the present paper, we investigated the potential of Polyetherether- ketone (PEEK) and its amorphous (PEEK A) and semi-cristalline (PEEK SC) states as interlayer materials, co-cured onto the thermoset composite. A surface preparation by atmospheric plasma process demonstrated that both PEEK state materials can be used as interlayer with auspicious resulting ad- hesion properties. The influence of the plasma treatment on surface properties and morphology is also experimentally characterized. An infrared (IR) welding process, barely studied in the literature, is studied to assemble hybrid struc- tural composite. In order to avoid the expected thermal degradation of the thermoset matrix, a dissimilar infrared heating input power is proposed. More- over, to decrease the possible thermal degradation of the thermoset composites during the fusion bonding, a dissimilar infrared welding process have been ex- plored. Single lap shear test and failure mode analysis have been performed to highlight the promising performance of PEI as well as PEEK interlayer based hybrid joint. |
