Tensioned CFRP reinforcement
In recent years, carbon-fibre (CF) composites have come to play a major role in structural post-strengthening. Yet, such applications have so far failed to fully exploit the high strengths and the multi-functionality of CF composites, and their potential for new-build structures is still not widely recognised. The paper makes proposals as to how better use may be made of the strength and multi-functionality of CF composites on future construction projects. In the construction sector, the current annual turnover of carbon fibre totals some 1500 tonnes worldwide. This roughly corresponds to three-quarters the amount used in the aviation and aerospace sectors. It should however be remembered that, at present, use of this material in the construction industry is almost exclusively limited to the post-strengthening of existing structures, with the new-build share remaining negligible. Applications as those described above would help to exploit the high strengths and the multi-functionality of CF composites. Use of CF composites for examples as the tension tether legs of an offshore platform anchored at a depth of 1100 m would generate a 600 tonne requirement per platform. Similarly, an 8 km span bridge using CF composites built across the Strait of Gibraltar (as yet an utterly unrealistic prospect) would need 105000 tonnes of the material. Use of CF composites for offshore platforms - certainly in the offing over the next few years - would provide a major boost to new-build applications.
