The limited quantity of modeling papers on halloysite nanotubes (HNT)-reinforced nanocomposites restricts the optimization of properties for multifunctional applications. In this paper, we develop a two-step technique to approximate the tensile strength for this category of materials. At the first stage, HNT and surrounding interphase are assumed as pseudoparticles and their strength is estimated by Kelly-Tyson approach. At the second step, a developed model predicts the strength of polymer nanocomposites containing polymer medium and pseusoparticles. Many experimental records of several examples and examinations of whole parameters evaluate the advanced technique. The experimental results and parametric checks demonstrate the desirable proofs approving the current methodology. Both interfacial shear strength and interphase strength straightly handle the strength of nanocomposites. The calculations reveal that the dimensions of HNT and interphase section can change the strength of HNT-reinforced samples by 280%. Nevertheless, the variations of HNT aspect ratio and polymer medium strength may improve the nanocomposite's strength by 470%. Additionally, high aspect ratio of HNT and poor polymer host are desirable for the strength of nanocomposites, while thick and short HNT (low aspect ratio < 33) cannot strengthen the polymer medium.

通过简单模型建立的两步技术来估算埃洛石纳米管填充的纳米复合材料的拉伸强度

埃洛石纳米管(HNT)增强的纳米复合材料上的建模纸数量有限,限制了多功能应用程序的性能优化。在本文中,我们开发了一种两步技术来估算此类材料的拉伸强度。在第一阶段,将HNT和周围相作为假粒子,并通过Kelly-Tyson方法估算其强度。在第二步中,已开发的模型将预测包含聚合物介质和假粒子的聚合物纳米复合材料的强度。多个示例的许多实验记录以及对整个参数的检查都评估了该先进技术。实验结果和参数检查证明了批准当前方法的理想证据。界面剪切强度和相间强度都可以直接处理纳米复合材料的强度。计算表明,HNT和相间断面的尺寸可以使HNT增强样品的强度改变280%。但是,HNT长径比和聚合物介质强度的变化可以使纳米复合材料的强度提高470%。另外,对于纳米复合材料的强度来说,高纵横比的HNT和不良的聚合物主体是理想的,而厚而短的HNT(低纵横比<33)不能增强聚合物介质。的力量提高了470%。另外,对于纳米复合材料的强度来说,高纵横比的HNT和不良的聚合物主体是理想的,而厚而短的HNT(低纵横比<33)不能增强聚合物介质。的力量提高了470%。另外,对于纳米复合材料的强度来说,高纵横比的HNT和不良的聚合物主体是理想的,而厚而短的HNT(低纵横比<33)不能增强聚合物介质。
