2.2.4. Analyzing the Microstructure of the Surface

Scanning electron microscopy (SEM) was used to document where the matrix material interfaced with the blended fibers. A test sample measuring 40 × 40 × 160 mm was cut using a saw into 1 mm slices, which were then used for SEM. A Phenom XL (ThermoScientific) was used with a magnification range of 80 to 100,000×.
