In doing so, the trade fair seizes upon a key theme in the industry: 45 per cent of surveyed companies expect the infrastructure/construction area of application to grow. In the prior survey, that figure was at just 35 per cent. The increasing use of composites doesn’t just benefit glass-fibre reinforced plastics (GFRP), which have dominated the construction sector for years; carbon-fibre reinforced plastics (CFRP) are also on the rise. According to the “Composites Market Report 2016” by CCev and AVK, worldwide consumption of the latter is expected to double to 12,100 tonnes by 2022.

Carbon concrete: Life cycle costs often favour CFRP

Carbon-reinforced concrete, or carbon concrete for short, holds great potential for the future.  This new element enables the design of thinner, more delicate structural components. “We started developing carbon concrete way back in the mid-1990s”, recalls Dr. Walter Begemann, the project manager of the VDMA Working Group Hybrid Lightweight Technologies in Frankfurt am Main. It took a long time for the new technology to prevail, however. “It wasn’t until 2016 when engineers from the Technische Universität Dresden received the Deutscher Zukunftspreis, the German President's Award for Innovation in Science and Technology, from then-German Federal President Joachim Gauck for replacing reinforcing steel cast in concrete with a mesh of carbon”, says the physicist and former managing director of the umbrella research organisation Forschungskuratorium Textil e.V.

According to the “Composites Market Report 2016”, carbon concrete is often deployed in reinforcements – like repairs of bridges or other structures. In such cases, the higher price is often immaterial when weighed against total life cycle costs. “The high price when compared to steel reinforced concrete is somewhat balanced by the cheaper and quicker assembly times, easier transportation and a sustainable stabilisation of constructions”, states the market report.

Focus Day Building and Construction

Designers, engineers, technicians and buyers with a focus on building and construction applications should reserve 20 September for a trade fair visit. The Focus Day Building and Construction will illustrate how composites can be deployed – alone or in combination with other materials – in the building and construction industry. The time-coordinated programme on the theme day will start at 10 am at the COMPOSITES FORUM in Hall 6/Stand B76. Expert lectures will explore the basics, trends and innovations of composites in the building and construction sector. Participation is free of charge.
