Hintergrund

Graphene, a form of a carbon where a single layer of carbon atoms creates a hexagonal (honeycomb) lattice, demonstrates a number of notable properties: it is said to be the strongest, the electrically most conductive whilst also being the thinnest material in the world. Other characteristics include its high thermal conductivity, very large surface area, stretchability, transparency and impermeability. It is a relatively new material that was produced for the first time in 2004 and won the Nobel Prize in Physics in 2010.

First industrial applications of graphene in FRP make use of it as a mechanical reinforcement in sports equipment such as tennis rackets or bicycles. This, however, only makes little use of graphene’s potential in FRP.  

Problemstellung

This project will include an initial literature review of graphene, its properties as well as current and potential applications. An emphasis shall be placed on the change in electrical properties when graphene is added to FRP as well as its use as a sensor in non-destructive testing and/or structural health monitoring of FRP. Using these findings, concepts shall be developed that use graphene as a sensor in GFRP for structural health monitoring and/or non-destructive testing. One of these concepts shall be verified by designing and building a test setup and testing specimens. The samples used during the experiments will be manufactured using graphene samples from an industrial partner.

Aufgabe

  • Literature review of graphene and its applications in composite materials especially as a sensor in structural health monitoring and/or in non-destructive testing
  • Concept development to use graphene as a sensor in in structural health monitoring and/or in non-destructive testing of GFRP
  • Manufacture of test specimens (GFRP with addition of a graphene-based sensor)
  • Development and verification of a test setup that can evaluate the response of the graphene-based sensor
  • Preparation and evaluation of experimental data
  • Written documentation

Anforderung

  • Basic knowledge of composite materials is recommended
  • Understanding of electronics is an advantage
  • Interest in practical work
  • Responsible and reliable work attitude
  • Communication during the project in German or English. Since this project is conducted in cooperation with English-speaking industrial partners, the report needs to be written in English.

Kenntnisgewinn

  • Development of a test setup for measuring electrical signals in FRP
  • Development, integration and evaluation of a graphene-based sensor in FRP
  • Ability to design, conduct and evaluate experiments
  • Writing of scientific reports in English
