Opis:
A single polymer composite comprises a composite built out of fibres and a matrix, both made of the same or a very similar polymer material, where the components may differ with: molecular mass, density or branching degree. Such thermoplastic composites provide the beneficial mechanical characteristics required for reinforced materials, and their great advantage is the ease of full material recycling after the end of use. The aim of the presented work is to provide a description of the manufacturing technology, with a definition of the possibility for the waste of single polymer polyester composites to undergo a full material recycling process, oriented towards use in shipbuilding. A proposed idea for recycling is in the preparatory stage and its assumptions and the process followed will be the subject of a patent application. This work forms part of the studies realized in the scope of the REP-SAIL Project under the ERA-NET Transport III Initiative Future Travelling, carried out at the Maritime University of Szczecin, and the prepared doctoral thesis entitled “Manufacturing, shaping of operational properties and recycling of single polymer composite materials”.

Opis:
This article presents joining methods (welding and sealing) of single-polymer composite materials in a hot air stream. The research material was created using the film-stacking method, which involves pressing successive fractions of polyethylene terephthalate-modified with glycol (PET-G) at defined technological conditions, such as pressure, temperature, and time. Joining method analysis was carried out based on the tensile test results. Analysis of the obtained results showed that the properties of the overlapped weld joint were the best because they were closest to the original materials. In contrast, PET-G welded joint properties were the worst because the PET-G welded joint does not contain fibers, which enhanced the weld; therefore, the fastest breakage of the material was observed at the welding location. For the overlapped weld, the weld itself is more resistant because the joint surface is influenced by friction forces between joined materials.
