In Horizon 2020, funding for research and innovation in the railway area was entirely channeled through the Shift2Rail Joint Undertaking (Shift2Rail). Shift2Rail was founded in 2014 as a Public-Private Partnership between the European Union (EU) and the rail industry and aimed to coordinate and manage EU research and investment in the rail sector....

One of an important element of the railway system are stations. They are addressed in the project Innovative Solutions in Future Stations, Energy Metering and Power Supply called IN2STEMPO within Shift2Rail Joint Undertaking of Horizon 2020. The IN2STEMPO Future Stations projects actions lead to improve the quality of customer service and safety at...

Various inorganic additives belonging to four different groups: layered materials, metal hydroxides, metal oxides/carbonate and metal borates are investigated in bisphenol A polycarbonate/silicon rubber/bisphenol A bis(diphenyl phosphate) (PC/SiR/BDP) to improve flame retardancy. The pyrolysis, reaction to small flame and fire behaviour of the blen...

The reactivity of the flame retardant and its decomposition temperature control the condensed- phase action in bisphenol A polycarbonate/acrylonitrile–butadiene–styrene/polytetrafluoroethylene (PC/ABSPTFE) blends. Thus, to increase charring in the condensed phase of PC/ABSPTFE + aryl phosphate, two halogen-free flame retardants were synthesized: 3,...

The pyrolysis and flame retardancy of a bisphenol A polycarbonate/silicon rubber/bisphenol A bis(diphenyl phosphate) (PC/SiR/BDP) blend were investigated and compared to those of PC/BDP and PC/SiR. The impact modifier SiR consists mainly of poly(dimethylsiloxane) (PDMS> 80 wt %). The pyrolysis of PC/SiR/BDP was studied by thermogravimetry (TG), TG-...

Solid residues of bisphenol A polycarbonate (containing 0.45 wt% poly(tetrafluoroethylene))/silicone acrylate rubber/bisphenol A bis(diphenyl-phosphate) (PC/SiR/BDP) and PC/SiR/BDP/zinc borate (PC/SiR/ BDP/ZnB) after thermal treatment were investigated by solid-state and liquid-state NMR, focusing on the role and interaction of SiR with the other c...

Structural changes in the condensed phase of bisphenol A polycarbonate (containing 0.45 wt% poly (tetrafluoroethylene))/silicone acrylate rubber/bisphenol A bis(diphenyl-phosphate) (PC/SiR/BDP) and PC/SiR/BDP/zinc borate (PC/SiR/BDP/ZnB) during thermal treatment in nitrogen atmosphere and in fire residues were investigated by solid-state NMR. 1H, 1...
