An in-situ imaging technique for the determination of materials delamination has been developed at the Pennsylvania State University. A modified scanning acoustic microscope (SAM) has been used for the in-situ observations of material changes at intermediate temperatures 0-500 °C. The SAM was applied to image the healing process of internal defects of the graphite fiber reinforced poly(ether ether ketone) caused by a soft body impact. Results demonstrate the usefulness of the SAM imaging with temperature control to high enough temperatures to monitor in-situ materials undergoing changes in the internal structure.
