Research activities
The HUN-REN-BME Research Group for Composite Science and Technology (formerly MTA-BME Research Group for Composite Science and Technology) was founded on 1st July 2012on the basis of the Research Group for Process Metallurgy led by László Gillmeot, János Prohászka and János Ginsztler between 1961 and 2011. The new Research Group kept its values, traditions however expanded its research areas following and adapting to the present international trends, new research directions, long-term European Union priorities, international research goals and the strategy of the BME as a research university.

The aim of the research group: to develop innovative composite materials and technologies
In the research and development of composite technologies, we focus on the characteristics of composite materials and their components, as well as on the principles, processes, tools and machines for the production of composite products, with particular emphasis on the modification of material properties. We focus our research activities on materials (polymers, metals, ceramics) that are essentially different in terms of functionality and type of material, but which can complement each other.
In the research field of high-performance and smart composites, we aim to extend the range of applications of composites by improving their structure, e.g. by optimising their layering by providing them with additional functionalities. We aim to develop a non-destructive condition assessment technique based on digital image correlation by integrating full-field optical strain gauging and acoustic emission tools. We will also analyse the recycling potential of carbon fibre composites.
In our research on functional and nanocomposites, we use nanofibres to modify the properties of the composites, mainly to prevent delamination and to achieve more tough behaviour. Using nano- and microfibres, we are attempting to create self-reinforced composites. We are also incorporating nanofibres and fillers into thermoplastic polymer matrix composites to provide enhanced conductivity, shape memory, self-healing properties and are investigating the production technologies and behaviour of these materials. We will investigate the advancement of 3D printing processes for the fabrication of fibre reinforced composites.
In our research on biomaterials and biocomposites, we focus on the development of biopolymers that fit well into the circular economy model. We pay high attention to the investigation of novel biopolymers, their foaming and the development of multi-component biopolymer blends containing different types of biopolymers, plant and/or mineral reinforcing agents and crystallisation-inducing clot-forming agents. We complement this research by investigating the properties and application technologies of bio- and medical technology materials and by the production of medical devices.
