本研究的目的是探讨微米级和纳米级碳酸钙（CaCO 3）颗粒增强聚酰胺66（PA 66）的可能性。为此，微米级和纳米级碳酸钙颗粒被用作填料，以制备微复合材料（传统的复合材料）和纳米复合材料通过聚合物溶液的方法。发现微米复合材料和纳米复合材料具有比纯PA 66更高的模量和更低的强度。此外，纳米复合材料比微米复合材料具有更高的模量和强度。使用混合物规则、Guth、Nicolais-Narkis、Hashin-Shtrikman和Halpin-Tsai方程进行弹性模量的理论预测。计算结果表明，这些方程不能准确地预测所进行的工作的结果。然而，由于实验数据高于计算值，因此这些模型可以有信心地用于预测弹性模量。Polym.比较器：2009.© 2008年塑料工程师协会
The objective of this research was to investigate the probability of reinforcing Polyamide66 (PA66) with both micron-sized and nanosized calcium carbonate (CaCO3) particles. For this purpose, micron-sized and nanosized CaCO3 particles were used as fillers to prepare microcomposites (conventional composites) and nanocomposites via a polymer solution method. The microcomposites and nanocomposites were found to have higher modulus and lower strength than neat PA66. Also, nanocomposites had higher modulus and strength than microcomposites. Theoretical prediction of elastic modulus was carried out using Rule of mixtures, Guth, Nicolais–Narkis, Hashin–Shtrikman, and Halpin–Tsai equations. Calculated results show that these equations cannot predict the results accurately for the work carried out. However, these models can be used with confidence for the prediction of elastic modulus as experimental data are higher than the calculated values. POLYM.
