Abstract: This was an investigation into the development of liquid core optical fibers for the detection and self repair of cracking in cement or polymer materials generated by dynamic or static loading. Hollow glass fibers filled with liquid can act as a fiber optic. Volume and location of liquid released from the brittle fiber can be determined, thus revealing the matrix crack volume and matrix crack location. The liquid released in the matrix for the purpose of crack assessment, can also be used to repair these cracks. Further techniques for crack assessment and repair have been developed based on results from this research. This research was sponsored by NSF.!3
