Abstract

The interlaminar structure and dynamic mechanical properties of Tectona grandis fiber (TGF), polypropylene fiber (PPF), and carbon nanotube (CNT) nano composite were investigated in the current study. In order to improve the mechanical characteristics and microstructure, the present investigations used T. grandis fiber and polypropylene fiber (inorganic–organic) materials mixed with nano composite and epoxy resin. Strong bonding strength and high wear resistance were created by the silane characteristics during the coating process for the outer surface layers. Since CNT nanomaterials were directly reflected onto the outer surface, the microstructure analyses amply demonstrated that hexagonal lattice structure and crystallisation development were detected in the inner surface layer. In order to increase high stiffness and bonding strength, storage modulus and loss modulus values were applied to all composite materials, and the TGF/PPF/CNT composite materials’ hardness value was developed at 112 HV. The tensile strength of TG/PP composite was 46.7 MPa, while that of TGF/PPF/CNT composite was 57.4 MPa. Studies on wear resistance showed unequivocally that the TGF/PPF/CNT composite reduced wear and friction.

增强固态浸渍涂层工艺制备的大叶桉纤维（TGF）/聚丙烯纤维（PPF）/碳纳米管（CNT）纳米复合材料的层间结构和动态力学性能

本研究调查了柚木纤维（TGF）、聚丙烯纤维（PPF）和碳纳米管（CNT）纳米复合材料的层间结构和动态力学性能。为了改善力学性能和微观结构，本研究使用了无机-有机纳米复合材料与环氧树脂混合的柚木纤维和聚丙烯纤维（无机-有机）材料。在外层表层的涂覆过程中，硅烷的特性使其具有较强的粘合强度和较高的耐磨性。由于 CNT 纳米材料被直接反射到外表面，因此微观结构分析充分表明，内表层检测到了六方晶格结构和结晶发展。为了提高刚度和结合强度，所有复合材料都采用了存储模量和损耗模量值，TGF/PPF/CNT 复合材料的硬度值达到了 112 HV。TG/PP 复合材料的拉伸强度为 46.7 兆帕，而 TGF/PPF/CNT 复合材料的拉伸强度为 57.4 兆帕。耐磨性研究明确表明，TGF/PPF/CNT 复合材料可减少磨损和摩擦。

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.
