颗粒增强复合材料和纳米复合材料可以包含各种形态（例如球形、纤维和管状）的各种离散颗粒。材料的二维显微照片用于评估颗粒是否分散良好或分散不良，但通常使用所有颗粒均相同且为球形的假设。然而，我们表明，通过考虑椭圆形颗粒，离散颗粒的尺寸和形状可以改变系统的整体外观，而不改变潜在的机制。因此，我们的解释颗粒分散是通过比较我们的测量参考系统，考虑到颗粒的形态，并表明，差异所带来的过度简化。(C)2013作者由爱思唯尔有限公司出版。保留所有权利。
Particle-reinforced composites and nanocomposites can contain a wide range of discrete particles, of various morphologies (e.g. spherical, fibre, and tube). Two-dimensional micrographs of the material are used to assess whether the particles are well- or poorly-dispersed, but typically use the assumption that all particles are identical and spherical. However we show, by considering elliptical particles, that the sizing and shapes of the discrete particles can change the overall appearance of the system, without the underlying mechanisms changing. Thus our interpretation of particle dispersion is obtained by comparing our measurements to a reference system, which takes into account the particle morphologies, and demonstrates that discrepancies are brought on by oversimplification.
