Abstract

PurposeThe research aims to investigate the impact of thermo-mechanical aging on SBR under cyclic-loading. By conducting experimental analyses and developing a 3D finite element analysis (FEA) model, it seeks to understand chemical and physical changes during aging processes. This research provides insights into nonlinear mechanical behavior, stress softening and microstructural alterations in SBR compounds, improving material performance and guiding future strategies.Design/methodology/approachThis study combines experimental analyses, including cyclic tensile loading, attenuated total reflection (ATR), spectroscopy and energy-dispersive X-ray spectroscopy (EDS) line scans, to investigate the effects of thermo-mechanical aging (TMA) on carbon-black (CB) reinforced styrene-butadiene rubber (SBR). It employs a 3D FEA model using the Abaqus/Implicit code to comprehend the nonlinear behavior and stress softening response, offering a holistic understanding of aging processes and mechanical behavior under cyclic-loading.FindingsThis study reveals significant insights into SBR behavior during thermo-mechanical aging. Findings include surface roughness variations, chemical alterations and microstructural changes. Notably, a partial recovery of stiffness was observed as a function of CB volume fraction. The developed 3D FEA model accurately depicts nonlinear behavior, stress softening and strain fields around CB particles in unstressed states, predicting hysteresis and energy dissipation in aged SBRs.Originality/valueThis research offers novel insights by comprehensively investigating the impact of thermo-mechanical aging on CB-reinforced-SBR. The fusion of experimental techniques with FEA simulations reveals time-dependent mechanical behavior and microstructural changes in SBR materials. The model serves as a valuable tool for predicting material responses under various conditions, advancing the design and engineering of SBR-based products across industries.

循环载荷下碳黑增强丁苯橡胶的热机械老化

目的本研究旨在探讨在循环加载条件下，热机械老化对丁苯橡胶的影响。通过进行实验分析和开发三维有限元分析（FEA）模型，研究人员试图了解老化过程中的化学和物理变化。本研究结合了实验分析，包括循环拉伸加载、衰减全反射 (ATR)、光谱和能量色散 X 射线光谱 (EDS) 线扫描，以研究热机械老化 (TMA) 对碳黑 (CB) 增强丁苯橡胶 (SBR) 的影响。该研究使用 Abaqus/Implicit 代码建立了三维有限元分析模型，以理解非线性行为和应力软化响应，从而全面了解循环加载下的老化过程和机械行为。研究结果包括表面粗糙度变化、化学变化和微观结构变化。值得注意的是，在 CB 体积分数的作用下，观察到了刚度的部分恢复。所开发的三维有限元分析模型准确地描述了非线性行为、应力软化和非应力状态下 CB 颗粒周围的应变场，并预测了老化丁苯橡胶中的滞后和能量耗散。实验技术与有限元分析模拟的融合揭示了 SBR 材料随时间变化的力学行为和微观结构变化。该模型是预测材料在各种条件下反应的重要工具，可推动各行业基于 SBR 产品的设计和工程。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
