拉伸试验进行尼龙6/粘土纳米复合材料，有和没有POE-g- MA橡胶颗粒，在低于玻璃化转变温度和应变速率10-4至10-1 s-1的范围内。结果表明，屈服强度随温度和应变速率的Eyring方程，从而提供结果的激活能和激活体积的物理机制，在这些过程中所涉及的。此外，拉伸流变学响应表明，POE-g-MA橡胶颗粒的存在并没有改变纯尼龙6的剪切变形模式。相反，粘土层的存在改变了尼龙6的拉伸屈服变形从更偏塑性到更偏塑性。在尼龙6/粘土/POE-g-MA三元复合材料中，体积应变响应表明，POE-g-MA橡胶颗粒促进剪切变形，抑制粘土层分层屈服。
Tensile tests were conducted on nylon 6/clay nanocomposites, with and without POE-g- MA rubber particles, over a range of temperatures below the glass transition and strain rates 10-4 to 10-1 s-1. It was shown that the yield strength varied with temperature and strain rate as the Eyring equation thus providing results on activation energy and activation volume for the physical mechanisms involved in these processes. Additionally, the tensile dilatometric responses indicated that the presence of POE-g-MA rubber particles did not alter the shear deformation mode of neat nylon 6. In contrast, the presence of clay layers changed the tensile yield deformation of nylon 6 from the more deviatoric plasticity to the more dilatational plasticity. In nylon 6/clay/POE-g-MA ternary nanocomposite, the volume strain response showed that POE-g-MA rubber particles promoted shear deformation and clay layers delamination was suppressed at yield.
