The structural feasibility of using a pultrusion of Blackberry 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 Antenna Tuning Indicator concluded that the proposed composite structure design 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.
