The friction stir process (FSP) method used to prepare polyamide 6 (PA6)/nitrile-butadiene rubber (NBR) nanocomposites with 1 wt% Graphene nanoparticles. Response surface methodology (RSM) and Box-Behnken design were used to study the effects of four input variables including tool rotational speed (ω), shoulder temperature (T), traverse speed (S), and the number of passes (N) on tensile strength and impact strength of PA6/NBR/Graphene nanocomposite. In order to investigate the dispersion state of Graphene and the morphology of the PA6/NBR blend in the presence of Graphene, wide x-ray patterns (WAX), scanning electron microscopy (SEM) were performed. Furthermore and differential scanning calorimetric (DSC) was used to investigate the thermal properties of PA6/NBR containing 1 wt% Graphene nanoparticles. The results confirmed that at the optimum range of input variables, PA6/NBR/Graphene nanocomposite provided good thermal stability as well as the highest tensile strength, and impact strength. This is caused by the large surface area to volume ratio of the dispersed layered Graphene in PA6/NBR blends. Under optimal conditions of the rotational speed of 1200 rpm, traverse speed of 20 mm/min, shoulder temperature of 125°C, and number pass of 3, the maximum tensile strength and impact strength are 70.4 MPa and 70.3 J/m, respectively.

摩擦搅拌工艺 (FSP) 方法用于制备具有 1 wt% 石墨烯纳米颗粒的聚酰胺 6 (PA6)/丁腈橡胶 (NBR) 纳米复合材料。响应面方法 (RSM) 和 Box-Behnken 设计用于研究四个输入变量的影响，包括工具转速 (ω)、肩部温度 (T)、横向速度 (S) 和通过次数 (N) PA6/NBR/石墨烯纳米复合材料的拉伸强度和冲击强度。为了研究石墨烯的分散状态和 PA6/NBR 共混物在石墨烯存在下的形态，进行了宽 x 射线图案 (WAX)、扫描电子显微镜 (SEM)。此外，差示扫描量热法 (DSC) 用于研究含有 1 wt% 石墨烯纳米颗粒的 PA6/NBR 的热性能。结果证实，在输入变量的最佳范围内，PA6/NBR/石墨烯纳米复合材料提供了良好的热稳定性以及最高的拉伸强度和冲击强度。这是由 PA6/NBR 混合物中分散的层状石墨烯的大表面积与体积比引起的。在转速1200 rpm、横动速度20 mm/min、肩部温度125°C、道次次数为3的最佳条件下，最大拉伸强度和冲击强度分别为70.4 MPa和70.3 J/m。
