Carbon fibers (CF) are now more frequently used in composite materials due to their extremely high rigidity and strength - in recent years are also increasingly used in the construction industry. For concrete, this compound is not always sufficiently solid, especially at higher temperatures. Carbon concrete is considered to be the building material of the future: Lightweight, flexible and needing significantly less resources than reinforced concrete.
The Institute of Construction Materials and the Institute of Structural Analysis at TU Dresden have collaborated with Shanghai Jiao Tong University in China to research which methods could be used to achieve even more stable composites. These include both technological and physico-chemical approaches that can provide improved fiber-matrix interaction at different temperatures. Both textile-technological approaches, such as suitable coating or impregnation materials, and physico-chemical methods using plasma treatments or electrochemical deposition were identified as particularly promising.
In a major review article published in the renowned "Progress in Materials Science", a journal with an exceptionally high impact factor, the researchers from TU Dresden and Shanghai Jiao Tong University have now been able to present to a large specialist audience a comparative analysis of the various modification methods that are intended to enable improved load transfer between carbon fibers and cement-based matrices.
The article in the internationally highly respected journal "Progress in Materials Science" is a phenomenal success for the Dresden-based researchers. The publication in the journal is an indication that the issue of improved fiber composite in cement-based matrices, previously relevant mainly in research by civil engineers, has been brought to a fundamental level that has now gained importance for a much wider professional community.
