Description of the research topic:
a.) Antecedents:
Our research group is developing a hybrid technology that enables the production of high-performance composite structures with a recyclable thermoplastic matrix. The hybrid technology under development combines the advantages of the three most promising processes - thermoplastic resin infusion (T-RTM-thermoplastic resin transfer molding), injection molding, and 3D printing - during the production of a single component. These hybrid composites can have lower weight and better mechanical performance, aesthetic design, and complex shape while remaining recyclable.
b.) Aim of research:
The research aims to develop methods to build special molds for these lightweight composites and hybrid composite structures.
c.) Tasks, main items, necessary time:
• Prepare a literature review on lightweight composites, injection molding, T-RTM, and 3D printing. The main focus of the literature review is to define the most modern research results in lightweight polymer composites. (approx. 12 month)
• In the first stage, we will focus on the combinations of the three technologies and the possible interactions through the molds. (approx. 20 month)
• We will develop methods to combine the advantages of these technologies. (approx. 16 month)
d.) Required equipment:
The necessary equipment is available at the department laboratory; some test devices are also to be developed and built as a part of the research.
e.) Expected scientific results:
The final target of the research is to define the best approaches for the mold construction of hybrid lightweight polymer composites.
