Abstract
The widespread deterioration of timber sleepers combined with an intensified pressure on limiting the use of hardwood timber because of various environmental concerns are the main drivers of research conducted throughout the world directed towards finding a suitable alternative for replacing timber sleepers. While many railway infrastructure companies have long been trialing pre-stressed concrete and steel for replacing timber sleepers, this has gained limited success as these materials have not proven reliable alternatives to timber turnout sleepers. Research and development has now been focused on fibre composites as this material can be made to have similar usability and design characteristics to hardwood timber with the added advantages. However, several challenges need to be overcome for fibre composite sleepers to become a suitable alternative to timber sleepers. This paper provides an overview of the various initiatives at the Centre of Excellence in Engineered Fibre Composites which aims to further the understanding of the design and performance issues associated with the eventual application of this new technology. Results of the on-going research and development on sleeper material made from a new generation fibre composite sandwich structure for replacement sleepers in a railway turnout are highlighted in this paper.
