Abstract

Self repair for structures, which I invented in 1989, is designed to incorporate hollow vessels, usually fibers, which will release a repairing agent when the structure is damaged, so that the repairing agent will fill delaminations, voids and cracks, thus healing both matrix voids and rebonding fibers. The repaired damage will enable continued function and prevent further degradation to catastrophic failure. Repaired damage will enable applications to be utilized under current standard operating procedure without reduction in performance due to impacts The benefits are: 1) safety of bridges and highways, lives saved, money saved 2) reduced maintenance expenditure, 3) extended life cycle and reduced maintenance costs 4) lighter weight infrastructure components such as bridges due to a reduction in overdesign safety measures. The benefit is truly in the economy, readiness, and effectiveness of all infrastructure applications Two materials are important in infrastructure as the matrix material, polymers and concrete. Natural Process Design, Inc. works in both areas to develop self repair.. A small part of that research is presented here.
