Polymeric nano-materials utilization in reinforced concrete, aiming to deal with steel corrosion was developed in previous works. Promising results were obtained with PEO–b–PS nano-formations, both in terms of enhanced bulk matrix properties and improved steel corrosion resistance. Recent research has been focusing on a cheaper and commercially...

Advances in the study of composite polymeric materials for structural applications have suggested the possibility of an early elimination of cracks to avoid macroscopic damage of the material. Hence, the concept of self-healing composite materials has been introduced to reduce the maintenance cost and frequency, to increase the life in service...

Structural ceramics like alumina are usually brittle and sensitive to flaws leading to a reduction in their mechanical properties. This situation is worsened by machining prior to service and during service by contact, which introduces micro cracks and hidden damages. Crack damage can easily be developed in such ceramics when loaded, which often...

The subject of this paper is the mathematical modelling of the crack self-healing process. For self-healing modeling of cracked structures the bridged crack approach is used. In the frames of this approach is assumed: 1) there is a crack in a structure after service loading; 2) there are bonds between surfaces of a crack (which are induced by a...

Since self-healing of cracks is able to improve the durability of concrete structures, it has attracted much attention in the recent years. As known, in concrete matrix there are large amounts of cement grains remaining unhydrated, particularly in high performance concrete. Further hydration of these unhydrated cement grains has potential to...

In this work, we investigate the formation of self-healing systems that are able to recover more than once more than one (mechanical or other physical) functionality. To this aim composites were created consisting of a polysulfide thermoset rubber matrix having intrinsic self-healing properties filled with thermally/electrically conductive...

Self-assembled systems formed of micelles or vesicles have frequently been discussed as model systems for self-healing materials because their structure is dictated by thermodynamics and hence they quickly restore upon perturbation. In this aspect, they mimic many natural systems such as biological cells. However, in contrast to most synthetic...

An international cooperation research project has been financially supported by China Nature Science Foundation, which consists of three relatively independent, but strategically integrated research sub-programs, aiming at the formation of a selfhealing system based on the microcapsule principle for the cementitious composites. In this paper, a...

Locally stiffened or ‘stringer’ - skin composite structures are extensively used for lightweight applications in the aerospace industry. Due to localised stiffening, stress concentrations arise which can initiate damage e.g. debonding or delamination, within the composite structure. Critically, this damage can propagate under fatigue loading...

For a microcapsule based self-healing system in the cementitious material, a fundamental issue is to find and facilitate a suitable microcapsule system, concerning either the material selection or design and manufacture process. In this study, urea formaldehyde resin is used for the shell of microcapsule, and bisphenol – an epoxy resin E-51...

Creation of an ideal self-healing polymer composite material with durable performance could become an alternative to traditional improvement of lightweight constructions. A vascular strategy of the self-healing of the epoxy materials is based on healing agent (HA) delivery to the damage via system of channels formed in the material. The aim of...

Fiber reinforced cementitious composite (FRCC) has a great capability for selfhealing of cracks. Concrete cracks with a sufficiently small crack width (below 0.1 mm) can be closed and self-healed by crystallization of calcium carbonate in the presence of moisture, even in the case of ordinary concrete. Such precipitation is caused by reaction of...

Poly (urea-formaldehyde) (PUF) shelled dicyclopentadiene (DCPD) microcapsules were prepared by in-situ polymerization technology for self-healing concrete applications. It’s found, during the process, sodium dodecyl benzene sulfonate (SDBS) behaves better in emulsification of DCPD than other surfactant of sodium lauryl sulfate (SLS) and styrene...
