Since the 1970ties there are visions of large civil structures made of advanced composites. Up to now none has been realized. One important reason is that most civil engineers do not trust fibre reinforced polymers. Nevertheless since about ten years carbon fibre reinforced polymer (CFRP) strips are worldwide successfully applied to post-strengthen civil structures. CFRP cables would be perfectly suited as tendons for suspended bridges and large roofs. They proofed since twenty years in pilot projects to be very reliable. Based on these positive experiences German authorities permitted now the construction of a railway bridge with CFRP hangers. This may be a trigger for large structures with advanced composites in future.
