Paths and hurdles for FRP in construction
Fibre composites have been used successfully in the building industry for over 50 years. Glass fibre reinforced plastics in particular have proven themselves in pipes, tanks, covers or roofs, bridges and cooling towers due to their mechanical properties and corrosion resistance.
Nevertheless, these materials are not able to be equated with classic materials such as steel, concrete or wood in the minds of planners and users. They are often regarded as exotic and structures made of GFRP or CFRP as pilot projects.
What are the main reasons for this? On the one hand, fibre composites are not equally represented in civil engineering studies. On the other hand, fibre composites are unregulated products and are available in an unbelievably large range of combinations. There are no tables for the use, but it requires specific expertise. For orientation there are standards such as DIN EN 13121, the recommendation "Tragende Kunststoffbauteile des Bau-Überwachungsvereins (BÜV)"; for the design, construction and dimensioning of load-bearing structures in building construction and civil engineering or the "Guidelines and Recommended Practices for Fiber-Reinforced-Polymer (FRP) in Architectural Products"; of ACMA.
The basic ways of placing on the market are regulated, for example, by approvals in individual cases (ZiE), general technical approvals (abZ) or ETAs.
In addition to the general conditions, the presentation will discuss what needs to be done in order to get more fibre composites into applications in the construction industry.
