Composite Railway Sleeper: A Cost Effective And Eco-Friendly Alternative, Wahid Ferdous, Allan Manalo, Thiru Aravinthan, Gerard Van Erp

High maintenance cost, huge carbon-dioxide emission from cement and steel industries and early failures of the traditional timber, concrete and steel sleepers motivated the composite sleepers as an alternative to replace those in the existing rail track. This poster presented the optimised composite railway sleeper concept and their static performance in laboratory scale. Results found that the optimised shape can reduce two-third volume of materials from the traditional rectangular shape and their behaviour is comparable with timber sleeper.

Structural optimisation of composite railway sleeper is becoming an important area of research to effectively use composite materials and minimising their manufacturing costs. This study used the finite element approach to structurally optimise a composite sleeper for a mainline railway track and evaluate their performance. Strand7 finite element simulation is executed to achieve this goal. This study presents the optimised shape of a sleeper which requires only one-third volume to that of a standard rectangular sleeper. The performance of the optimised sleeper is determined in a high and low stiffness support foundation and the results obtained from this analysis are …
