简介
The future of transportation involves the reduction of emissions by the transition from individual to communal types of transport and lowering the consumption of energy. Railway, in particular, stands out from other types of transports since it consumes less energy, requires less space and produces less CO2. Further emission reduction in railway vehicles may be promoted by their weight decrease. This would not only lower the required energy in cruising regimes, but also facilitate accelerations and reduce braking/propulsion wear. Additionally, the mitigation of railway noise/vibration would increase the attractiveness of this transports on a passenger point-of-view. It may be understood that both issues could be addressed by using lightweight materials with enhanced vibration and noise damping. This study proposes the design of such a material, also considering its structural strength. It is suggested that composite …
