Project summary

A new MTA–BME Momentum Research Group for Lightweight Polymer Composites has been established at Budapest University of Technology and Economics, Faculty of Mechanical Engineering, Department of Polymer Engineering. The main aim of the research project is to create a comprehensive technological and modeling background for the novel hybrid TCM (thermoplastic composite material) process. In the project, the researchers will characterize the polymerization kinetics, crystallization kinetics and viscosity of the in situ polymerized thermoplastic for numerical modeling of the T-RTM (Thermoplastic-Resin Transfer Molding) process. Reinforcement structure development will be in focus regarding short and long fibers, such as conventional and 3D printing-based preform technologies for the designable load-bearing structures. Overmolding and overprinting will be further developed as conventional T-RTM technologies are limited in geometries. The project will focus on the numerical modeling and recyclability of these polymers, composites and hybrid composites.

Section 2
1 September 2021 - 31 August 2022
In the second year, the research group was expanded with additional members and focused on the development of technology and raw materials. The only difficulty was the acquisition of a 3D printer, as it was not possible to obtain equipment on the market that would meet the needs. To solve this, we developed and manufactured our own endless fiber composite printer from the available budget and external support. The research group successfully applied and thus became part of the RRF-2.3.1-21-2022-00009 – Renewable Energies National Laboratory (2 departments and the research group are members of the application from BME). In the application, the Lendület research group will carry out the practical application of theoretical developments, in which they will create a lightweight hydrogen cell containing only polymer composite main elements by combining T-RTM, injection molding and endless fiber composite 3D printing over the next 3 years. During the reporting period, two doctoral students completed their doctoral work on the research group's topic and submitted their dissertations.

Section 3
1 September 2022 - 31 August 2023
We achieved our goal of developing a hybrid technology that combines the advantages of injection molding, 3D printing and T-RTM technologies for the production of high-performance, recyclable polymer composite structures. We developed injection molding and T-RTM tools for these complex analyses, which resulted in a doctoral thesis. We implemented the further development of the T-RTM technology by improving the polymerization (conversion). We solved the surface improvement of the T-RTM product with a coating process, which also resulted in a doctoral thesis. We developed an industrial-scale, endless-fiber-reinforced 3D printer, with which we created preforms and inserts for injection molding and T-RTM technologies. We developed an accurate simulation method for calculating the strength of the connection between the components of the injection molding technology. We joined the National Laboratory of Renewable Energies to develop lightweight polymer composite components for energy cells.

Section 4
1 September 2023 - 31 August 2024
In the fourth year of the project, we have made significant progress in the field of in situ polymerization and T-RTM technology. We have developed a polyamide foam core for T-RTM composites, and we have created functionally integrated composite structures that include a combination of a surface layer and a foam core. In addition, we have analyzed the ultrasonic weldability of carbon fiber reinforced polyamide composites manufactured using T-RTM technology using different carbon fiber systems. We have also made significant developments in the field of 3D printing, especially in the printing of multi-component composites. We have created filaments with a high fiber content, continuous reinforcement, and developed and tested in-situ foaming filaments. In addition, we are investigating the technology and the mechanical and morphological properties of the printing of composite sandwich structures, and we are modeling the load-bearing capacity and energy-absorbing composite structures. In the field of injection molding, we developed highly filled polymer composites and analyzed the ultrasonic weldability of carbon fiber reinforced polyamide composites. We refined the control of the injection molding process using reinforcement learning, with particular attention to raw material changes and machine settings. In the field of simulations, we modeled bond strength and examined the effect of injection molding parameters on weld strength in partially crystalline materials. In addition, we applied new computational methods to predict the strength of collision defects. In order to demonstrate the practical utility of the work of the Lendület research group, we sought demonstration tools that would enable most of the technologies, materials, and methods we developed to be put into practice. As a result, the MTA–BME Lendület Lightweight Polymer Composites Research Group joined the National Laboratory for Renewable Energies (RRF-2.3.1-21-2022- 00009) in order to collaborate with o

Section 5
1 September 2024 - 31 August 2025
At the MTA–BME Lendület Lightweight Polymer Composites Research Group, our goal was to develop a hybrid processing technology that combines the advantages of thermoplastic resin transfer molding (T-RTM), injection molding, and 3D printing. With this approach, we have enabled the production of lightweight, high-strength, and fully recyclable composite structures without geometric limitations. We focused on improving the T-RTM process, particularly the in-mold polymerization, enhancing conversion efficiency, and reducing surface defects. As a result, we developed modified mold and coating solutions, which have led to several BSc, TDK, and PhD theses. To overcome the geometric constraints of T-RTM, we combined it with other processes, producing reinforcing ribs by injection molding or 3D printing, supported by new hybrid mold systems. In the field of 3D printing, we built our own continuous-fiber printer, capable of processing filaments with up to 50,000 individual fibers. The resulting directionally oriented, high-fiber-content preforms significantly increased the load-bearing capacity of hybrid structures. On the modeling side, we were the first to develop a simulation method that integrates resin flow, fiber infiltration, and in-situ polymerization phenomena. We also made it possible to predict the bonding strength at overmolded interfaces, a capability now implemented in the latest version of Moldex3D, one of the world’s leading injection molding simulation software packages. We also investigated recycling opportunities, modeling fiber breakage during reprocessing of short-fiber injection-molded composites and quantifying its effect on mechanical performance. Our results are now being applied in industrial and national collaborations, including the National Laboratory for Renewable Energies, where we are developing lightweight bipolar plates for hydrogen fuel cells using our hybrid technologies. We are also working on lightweight polymer composite gear systems
