Studying the Fabrication and Characterization of Polymer Composites Reinforced with Waste Eggshell Powder

Figure 4

SEM images of the fractured surfaces of cured PA10 composites: (a) Overview of the fracture surface reveals the distribution of the ES particles in the PA matrix, (b) Reveals an embedded ES particle in the PA matrix, and (c) reveals de-bonded ES particle from the PA matrix. Circles in (a) show pull out particles (ES) from the matrix (PA). Arrows in (c) show a noticeable gap between the ES particle and PA matrix.
