(author)Symposium organised by Ghent University, Department of Structural Engineering and Delft University of Technology, Aerospace Structures & Materials. Materials play an extremely important role in our lives. These materials may be of a very different nature ranging from metals over concrete to polymers and composite materials. They all have in...book 2013

Lafont, U.L. (author), Van Zeijl, H. (author), Van der Zwaag, S. (author)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...conference paper 2013

Lafont, U.L. (author), Van Zeijl, H.W. (author), Van der Zwaag, S. (author)While conventional self healing materials focus on the restoration of mechanical properties, newer generations of self healing materials focus on the restoration of other functional (i.e. non-mechanical) properties. Thermal conductivity is an example of an important functional property of a Thermal Interface Material (TIM) for LED’s and...conference paper 2013

Bose, R.K. (author), Garcia Espallargas, S.J. (author), Van der Zwaag, S. (author)Supramolecular rubbers based on 2-aminoethylimidazolidone and fatty acids with epoxy crosslinks have been shown to self-heal via multiple hydrogen bonding sites. In this work, several tools are used to investigate the molecular mechanisms taking place at the interface to understand cohesive healing in these polymers. The quantification of self...conference paper 2013

Vega Vega, J.M. (author), Van der Zwaag, S. (author), Garcia Espallargas, S.J. (author)Poly(ethylene-co-methacrylic acid) (EMAA) ionomers have shown healing capabilities in both ballistic and static tests. In previous studies it was shown that the degree of crosslinking (clusters) affects (positively or negatively) the healing under impact tests. Moreover, it has also been reported that the modification of the ionomers by...conference paper 2013

Van der Zwaag, S. (author), Zhang, S. (author), Fang, H. (author), Bruck, E. (author), Van Dijk, N.H. (author)We report the main findings of our work on the behaviour of binary Fe-Cu and Fe-Au model alloys designed to explore routes to create new creep resistant steels having an in-built ability to autonomously fill creep induced porosity at grain boundaries. The alloying elements were selected on the basis of their ability to be brought in...conference paper 2016

Kötteritzsch, J. (author), Hager, M.D. (author), Schubert, U.S. (author), Bose, R.K. (author), Garcia Espallargas, S.J. (author), Van der Zwaag, S. (author)Because of its thermal reversibility, the retro-Diels-Alder (RDA) reaction represents an appealing possibility to produce self-healing polymers with well-defined architectures and tunable properties [1]. However, the polymer architecture for which the Diels-Alder (DA) reaction can best be used to contribute to the healing process is still not...conference paper 2013

Bode, S. (author), Bose, R. (author), Sandmann, B. (author), Hager, M.D. (author), Garcia, S.J. (author), Van der Zwaag, S. (author), Schubert, U.S. (author)In the last decade several intrinsic self-healing materials have been developed in which the healing mechanism was mainly based on the reversibility of a certain structural element. For this purpose, reversible covalent bonds, e.g., based on the Diels-Alder reaction or weaker non-covalent interactions, e.g., hydrogen bonding, ionic interactions...conference paper 2013

A critical factor in structural design is the resistance of a structure to progressive damage which develops during its service time. The brittle nature of matrix cracking is the main source of composite failure initiating...conference paper 2013

(author)Steels are among the most widely used construction materials as their mechanical properties can be tuned over a very wide range of desired combinations of strength formability and other properties. However, when exposed for long times to high temperatures steel components can exhibit premature and low-ductility creep fracture, which arises from...conference paper 2013

Shen, L. (author), Li, S.B. (author), Van der Zwaag, S. (author), Sloof, W.G. (author)The oxidation crack healing of Cr2AlC and Cr2(Al,Si)C was studied and compared with known healing of Ti2AlC. The oxidation induced crack healing of Ti2AlC is relatively fast and leads to full strength recovery, but the oxidation product contains besides ?-Al2O3 also undesired TiO2. However, when oxidizing Cr2AlC only ?-Al2O3 is formed, but full...conference paper 2013
