Improved Bonding of Composites by Development of Controlling Interface Reactions

本课题主要研究聚合物/陶瓷复合材料的粘接性能。这种粘合是通过多孔壁聚合物纤维将有机聚合物化学品释放到有机基质中来实现的。这个想法很新颖，特别强大，因为它提供了一种自动修复这些键的方法，以防它们退化。通过经由现有的多孔壁聚合物纤维引入修复化学品来进行修复。该项目选择的化学品将提供所需的化学相互作用和可接受的毒性水平。还研究了修复化学品的输送系统及其控制，以达到目标剥离区。

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.
