Shell elements made of carbon-fiber reinforced concrete with functional integration

The thin-walled carbon concrete composite opens up totally new fields of application and thus it is subject of comprehensive research activities at the TU Chemnitz. Two reference pavilions consisting of carbon-fiber reinforced concrete were built as lightweight shell structures with functional integration, in order to transfer the scientific investigations into practice.

In the middle of last century, architects like Felix Candela and Heinz Isler have already built a large number of lightweight shell structures made of reinforced concrete. The results of their works are thin-walled structures featuring a particularly advantageous load-bearing behavior in respect of the building material concrete. However, the corrosion problems of the reinforcing steel in filigree structural elements with very small concrete cover as well as the complex and expensive formwork were an obstacle to further applications of this resource-conserving construction method.
