Investigation of Capsulated Epoxy and DCPD in Epoxy Based Self-healing Composites - DFT Calculation and Experimental Analysis
Epoxy and dicyclopentadien (DCPD) are two common healing agents, which are introduced into epoxy matrix through encapsulation in order to prepare self-healing composites. In a comparative study, the compatibility of healing agents and epoxy matrix is investigated through experimental tests and DFT calculations. The interaction energy is considered to be the determinative parameter in DFT calcul...
متن کاملSelf-Healing Polymers and Composites
Self-healing polymers and fiber-reinforced polymer composites possess the ability to heal in response to damage wherever and whenever it occurs in the material. This phenomenal material behavior is inspired by biological systems in which self-healing is commonplace. To date, self-healing has been demonstrated by three conceptual approaches: capsule-based healing systems, vascular healing system...
متن کاملSelf-healing thermoset using encapsulated epoxy-amine healing chemistry
Self-healing was achieved with a dual-microcapsule epoxy-amine chemistry in thermoset epoxy. One capsule contained a modified aliphatic polyamine (EPIKURE 3274) while the second capsule contained a diluted epoxy monomer (EPON 815C). Amine microcapsules were prepared by vacuum infiltration of EPIKURE 3274 into hollow polymeric microcapsules. Epoxy microcapsules were prepared by an in situ polyme...
متن کاملSelf-healing Polymers and Composites » American Scientist
Nothing lasts forever. Any humanmade material, used in anything from toys to bridges, will eventually fail, if not maintained and repaired. Traditionally, this problem has been addressed through extensive inspection and expensive replacement of damaged parts. Biological systems, however, have evolved to include alternative ways to repair internal and external damage via healing mechanisms. Mate...
متن کاملIntroduction: self-healing polymers and composites.
Self-healing materials are inspired by biological systems in which damage triggers an autonomic healing response. This new paradigm in materials design has led several exciting interdisciplinary approaches involving chemistry, mechanics and materials processing to successfully incorporate self-healing functionality in polymers and composites. The first clear demonstration of self-healing in an ...
