Optical fibers for sensing, healing and reinforcement
A hollow core optical fiber waveguide has been designed, fabricated and demonstrated for reinforcing, sensing strain and temperature and for healing cracks in a concrete beam. This paper discusses how hollow core and solid core optical fibers can be used to reinforce a concrete specimen, monitor parameters affecting the structure and be used to heal cracks occurring in the structure as well. Measurements of strain and temperature can be made using the liquid core optical fibers or can be inferred indirectly by collocated solid core fiber temperature or strain sensors. As soon as fiber sensors detect a crack or break in the concrete structure, a commercially available concrete restorer liquid is pumped through the hollow core fibers embedded in the structure and 'heals the structure'. The healing of the concrete structure and the measurement of strain and temperature using liquid core optical fiber sensors is discussed in this paper.
