Failure analysis of graphene/epoxy materials with acoustic emission technology

Project Description

Epoxy has a wide application in the coating and structural composites because of its good thermal and wear resistant properties, while graphene/epoxy is in great interest in engineering for further enhanced mechanical properties. Therefore, identification of failure stage of such materials, measuring the stress-strain characteristics, and structural health monitoring, has in high demand by researchers. The project will focus on applying the acoustic emission technology to the failure analysis of graphene/epoxy materials and identify the behaviors of the materials during tensile and fatigue tests. The acoustic emission signals will be directly measured by AEwin software, and signal processing algorithms, such as sampling and reconstruction, filtering, fast Fourier transform (FFT), short-time Fourier transform (STFT), and wavelet transform (WT), will be conducted in Matlab software. The result of acoustic emission will be compared to the tensile and fatigue test result and the properties of the material will be analyzed.

Work Description

The project includes lab works (measuremnt with sensors) in MSB and data analysis work with Matlab software.
