Primary particulate matter (PM) consists of chemical components suspended in the atmosphere as aerosols, e.g. as a result of exhaust gaseous and friction processes (e.g. braking). Such particles may potentially contribute to smog events in urban areas and might be responsible of negative effects on the environment (e.g. acid rain acidification, toxic effects on plants and animals) and health (e.g. cancer, respiratory issues). The challenge is therefore to develop a new generation of transport technologies able to reduce the contribution of traffic related and total particulate matter, and, at the same time, to comply with future and stricter legislations on vehicles emissions and EU air quality. The LOWBRASYS project aims at demonstrating a novel and low environmental impact brake system that will reduce micro and nanoparticles emissions by at least 50%. The measurement and understanding of micrometer-sized and ultrafine particles and their effects on health and the environment will be improved and whilst providing recommendations to policy makers. This goal will only be achievable by a systematic and structured approach focused by the LOWBRASYS Team on the following targets: 1. Novel materials formulations of the brakes pad and disc in order to reduce the total particle emissions and have a low-environmental impact. 2. Innovation of environmental friendly braking strategies (control systems) that reduce PM emissions. 3. Breakthrough technology for collection of particles near the PM source in order to further dramatically reduce PM emissions. 5. System integration of the novel pad, components and control systems in vehicles. 6. Improvement of the measurement techniques and understanding of the brake wear PM effects on health and the environment through state-of-the-art non-in-vivo techniques and related policy recommendations. Recommendations to policy makers will also be provided by the Team given no current applicable legislation in Europe.

Current technological demands are increasingly stretching the properties of advanced materials to expand their applications to more severe or extreme conditions, whilst simultaneously seeking cost-effective production processes and final products. The aim of this project is to demonstrate the influence of different surface enhancing and modification techniques on CF-based materials for high value and high performance applications. These materials are a route to further exploiting advanced materials, using enabling technologies for additional functionalities, without compromising structural integrity. Carbon fibre (CF) based materials have particular advantages due to their lightweight, good mechanical, electrical and thermal properties. Current generation CFs have extensively been used in a multitude of applications, taking advantage of their valuable properties to provide solutions in complex problems of materials science and technology, however the limits of the current capability has now being reached. MODCOMP aims to develop novel fibre-based materials for technical, high value, high performance products for non-clothing applications at realistic cost, with improved safety and functionality. Demonstrators will be designed to fulfil scalability towards industrial needs . End users from a wide range of industrial sectors (transport, construction, leisure and electronics) will adapt the knowledge gained from the project and test the innovative high added value demonstrators. An in-depth and broad analysis of material development, coupled with related modelling studies, recycling and safety will be conducted in parallel for two types of materials (concepts): CF-based structures with increased functionality (enhanced mechanical, electrical, thermal properties). CNF-based structures for flexible electronics applications. Dedicated multiscale modelling, standardisation and production of reference materials are also considered

There is a need to find solutions to replace Critical Raw Materials (CRMs) such as Chromium, Nickel, Molybdenium and Vanadium in high volume end consumer products. Steels and superalloys with considerable amounts of these CRMs are widely used in many industrial applications, particularly under extreme conditions where corrosion and wear resistance are needed. It is generally accepted, that intermetallics in particular low cost FeAl offer outstanding material properties. Unfortunately it is difficult to translate their properties to real products, as intermetallics suffer from low ductility at ambient temperature and poor machinability. The impact of FeAl intermetallics as a low cost Cr-free alternative for stainless steel would therefore be much higher if a cost effective industrial process would be available, that allows to manufacture complex 3-D geometries of almost unlimited shapes from small grain size (0.1-5 m) high ductility material. The main objective of EQUINOX is to develop a novel process that allows to substitute Cr/Ni based (stainless) steel parts used in high volume end consumer products such as in the lock industry, electronics, process industry and automotive industry with a novel near net shape production technology for a new class of highly advanced ductile Fe-Al based intermetallics. Ductility at low to medium temperatures, while maintaining good tensile strength and optimum level of residual stress will be based on a radical new production process that use abundant raw material Fe3O4 and Al2O3.
