You’d never know that from the realm of archery. Since around 05 people have been using those HighCountry arrows which are light to the point of non existence with bows ranging up to 90 lbs and the only problems most people have seen is glue failing to hold inserts together. In the case of a large building you’d be talking about prefabbing segments of floors and lifting them into place with helicopters or zeppelins. It would be much stronger than steel and many times lighter, there would be nothing in the picture to fail.
When carbon fiber bikes fail, they fail catastrophically. and it does happen more than one would think.
I used to feel the same way about carbon fiber as you do, though my feelings have changed after seeing such failures.
Carbon fiber is a combination of short strands held together in a plastic resin. The use of this technology for archery is great, since the engineering behind this is based on “compression” exerted over a longitudinal axis. The result is better penetration performance for overall mass.
Construction reinforcement materials work on a completely different scale of physics. Steel is the best material for reinforcing Concrete because it can be extruded as a seamless component, which is crucial to span and load bearing structures.
Modern methods of construction now eliminate Electrolysis by preventing an electrical ground in the steel reinforcement structure, which in turn eliminates internal corrosion. Steel reinforcement bar also is plastic coated which is the biggest corrosion deterrent due to electrolysis.
Using Carbon fiber on a massive scale for bridges and buildings simply would not work very well from a physical standpoint alone. It would also be very difficult to produce enough Petroleum based plastic resin to meet the demand of such a broad application as infrastructure.
