Acoustic emission monitoring on carbon fiber and epoxy materials

Project Description

Acoustic emission (AE), a non-destructive evaluation technology, has been investigated in its application on different materials by researchers. The proposed project aims to apply acoustic emission monitoring during the tensile test of carbon fiber and epoxy materials thus identify any cracks, slips, or dislocations prior to the failure. The characteristics of the AE signals, such as frequency spectrums, amplitudes, hits, power, etc. will be analyzed. A combined signal processing technology will be utilized to further extract valuable patterns from the directly measured data. The goal is to predict failure timing and location. Such methods can be further used in structural health monitoring.

  1. Conduct experimental tests including tensile test and AE data acquisition
  2. Process signals in AEwin and Matlab software
  3. Literature review
  4. Write report

Requirements Description

The student needs to have basic knowledge in Matlab or C/C++.
