Abstract Scope |
Particle spacing can significantly affect the mechanical and particle-dependent properties of particle-reinforced composites. Concepts such as particle dispersion and distribution express the relative adequacy of particle spacing; however, there exists no agreement in the literature on the best parameterization of these values. Additionally, the typical characterization techniques using optical or electron microscopy of cross-sections necessitate stereological arguments, which are often inconsistently applied. Here is presented a system built on three different methods of quantifying particle spacing: nearest-neighbor distance, interparticle distance, and free space distance. To assist interpretation of these varied particle spacing metrics, cross-section(s) of analyzed composites with descriptive captions are presented to complete this semi-quantitative characterization system. As an example, this system is applied to reveal the effect of changing volume fractions and fabrication techniques in a particular composite system. |
