2.2.5. Microstructural Analysis

The granite and ASPU fractured surface regions of specimens previously subjected to bending tests were observed through SHIMADZU's Super Scan SSX-550 scanning electron microscope (SEM) for microstructural analysis, at 20 kV of secondary electrons. The microstructural analysis is important to determine the quality of the adhesion between the particles and the resin and the presence of voids.
