The structural feasibility of using a pultrusion TEA TOWEL of carbon-fibre-reinforced polymers (CFRP) for the lightweight design of a mast for overhead line railway electrification was investigated and simulated.Material characterisation was undertaken using three-point bending and finite element analysis to identify the orthotropic properties of the pultruded tubes designed for a composite mast for overhead electrification.An innovative design of the mast was proposed and verified using a simulation that compared the deflection and stress levels under wind and inertial load.From the simulation results, it was concluded that the proposed composite structure design VITAMIN C SERUM complies with the mechanical performance requirements for its implementation and benefits the application with a weight reduction of more than 80% with respect to the current steel mast design.
