Introduction

Polymers are a highly resourceful class of materials that are found in all areas of engineering from avionics to biomedical devices. There is a rapid growth in the applications of polymeric materials and composite materials based on them especially due to reduced cost and manufacturing ease. Consequently, there are prospects for further growth in research and development. A good understanding of the properties of materials properties in varying environments and temperature ranges is central to sourcing the right polymer materials to suit specific applications.

NanoTest Vantage

The NanoTest Vantage system from Micro Materials combines several nanomechanical testing techniques into a single instrument. It can also operate at temperatures up to 750°C which means that it is being used increasingly to characterize high temperature and high performance materials and components such as airframes and avionics across the aerospace industry.

Assessment of Time-Dependent Behavior

Thermal stability of the testing device is the main factor for meaningful measurements of viscoelastic characteristics of time-dependent materials. At room temperature the thermal drift of the NanoTest is very low, usually an order of magnitude less than several other commercial systems.

Operation at High Temperatures

As temperatures rise, benefits obtained also increase especially because of the distinct, separate heating and active temperature control of both sample and probe, ensuring there is no heat flow during indentation.

Studies Conducted by the NanoTest Vantage

The NanoTest Vantage can be used to investigate the following:

  • Viscoelastic properties
  • Nanotribology
  • Elevated temperature nanoindentation
  • Testing in fluid environment
  • Ultra-high strain rate testing
  • Ultra-low load tests
  • Nano-scale fatigue testing

Conclusion

The NanoTest Vantage can be used to test several properties of polymer materials at high performance levels under conditions that simulate operating conditions to give a good indications of how they might perform.
