Use of advanced composites in civil engineering infrastructure Available to Purchase

This paper describes some of the composites initiatives in which the Taylor Woodrow Technology Centre has been involved, in order to highlight examples of how these advanced materials can add value to civil engineering projects. Polymeric composites comprise fibres of (typically) glass, carbon or aramid embedded within a resin matrix. The fibre and resin choices will influence the static and dynamic mechanical properties of the composite, as well as its impact resistance. These are tailored to satisfy the structural requirements of new-build or rehabilitation schemes. The examples identified in this paper relate to the rehabilitation of concrete, cast iron and steel elements, and research into the use of composites for long-span new-build applications. It will be shown how composites were used to meet programme and site working constraints in restoration work. The use of composites on their own and in combination with concrete, for new construction, will also be considered. The materials used were carbon and glass fibre-reinforced polymers (CFRPs and GFRPs). Client confidentiality is maintained by omitting site details.
