The improved bonding of polymer/ceramic composites is studied under this project. The bond is achieved by porous walled polymer fibers releasing organic polymer chemicals into an organic matrix. The idea is novel and especially powerful because it offers an automatic way to perform repair of these bonds in case of their degradation. The repair is performed by introduction of repair chemicals via the existing porous walled polymer fibers. The project performs a selection of chemicals that will provide both a desired chemical interaction and an acceptable toxicity level. The delivery system for repair chemicals and its control to reach the targeted debonding zone is also studied.

本项目对聚合物/陶瓷复合材料的粘接性能进行了改进研究。这种结合是通过多孔壁聚合物纤维将有机聚合物化学物质释放到有机基质中实现的。这个想法很新颖，而且特别强大，因为它提供了一种在这些键降解的情况下进行修复的自动方法。修复是通过现有的多孔壁聚合物纤维引入修复化学品来进行的。该项目选择了一些化学品，这些化学品将提供所需的化学相互作用和可接受的毒性水平。还研究了修复剂的输送系统及其到达目标脱粘区的控制。
