The literature review task defined in milestone 1 was prepared jointly by the BME Polymer Technology Department and X-Plast colleagues. The professional experience of the development team with numerous international patents greatly contributes to the achievement of the objectives of the milestone, so by focusing on the patent research of the selected gear type in the early stages of the work, a detailed mapping of the current state of science relevant to the topic was possible. This facilitated the accurate and efficient execution of the relevant international literature review. In addition, various polymer composite materials were developed, which we can use in injection molding and 3D printing processes for the production of gear parts. We have also prepared hybrid composites containing high-performance carbon fiber and boron nitride with different compositions, which combine the advantageous properties of the individual additives (high strength, good thermal conductivity, wear resistance, etc.). In the case of the raw material developed for 3D printing, we also developed an extrusion production method to maximize the length of the reinforcing fibers, thus improving the efficiency of the composites. In the work phase, we also prepared the tasks for the next milestone, examining possible outcomes and obstacles.
