Crystallite structure
WebAs a result, the oriented structures of the composites were obtained. This orientation of the structure affects the physical and mechanical properties of the polymer materials. The epoxy polymer has an amorphous structure, but epoxy composites with inorganic fillers have amorphous-crystalline structure. The average crystallite size is 14.5 nm. The orientation of crystallites can be random with no preferred direction, called random texture, or directed, possibly due to growth and processing conditions. While the structure of a (single) crystal is highly ordered and its lattice is continuous and unbroken, amorphous materials, such as glass and many polymers, are non-crystalline and do not display any structures, as their consti…
