The Centre of Excellence in Engineered Fibre Composites (CEEFC) at the University of Southern Queensland, Toowoomba, Australia has played a significant role in research and development of innovative fibre composite structures suitable for replacement of structural timber elements. Recently, a new generation fibre composite sandwich panel made up of glass fibre reinforced polymer skins and phenolic foam core has been developed and found to have strength and stiffness similar with that of hardwood timber. As these composite sandwich panels are produced in limited thicknesses, a structural beam is manufactured by gluing several of these sandwich panels together.
This paper presents the recent developments and successful applications of glue-laminated sandwich beams for structural engineering and construction. These include fibre composite railway sleepers, composite walers, and fibre composite replacement bridge girders. Future research and development on this innovative structural system are also discussed. A number of barriers that need to be overcome and the potential solutions for the continued growth and wide acceptance of glue-laminated sandwich beams in civil infrastructure and construction are also presented.
