Smart materials which sense, activate and repair damage; hollow porous fibers in composites release chemicals from fibers for self-healing, damage prevention, and/or dynamic control

The subject of this research is the sensing of damage such ascracking or corrosion in a settable material by a chemical or physical sensorwhich, in the process of sensing, starts the activation of a remedial orprevention process. It is a distributed system in which sensing and actuationrepair occur when and where they are needed.Materials containing various types of hollow fibers filled with a chemicalwhich releases into the matrix at appropriate times, or over time, are designedto address some of the major issues of material performance.
