摘要

本研究通过实验研究了功能分级多壁碳纳米管（FG-V MWCNT）玻璃纤维增强聚合物复合材料圆柱板的振动声学特性，这是一个通常通过数值方法进行探索的课题。本文介绍了实现 FG-V MWCNT 复合材料的新型工艺方法，并将结果与均匀分布和传统复合材料的结果进行了比较。利用内部开发的实验装置，测量了固有频率、模态振型、加速度和声压级 (SPL)。与传统复合材料相比，FG-V MWCNT 复合材料的基频明显提高（21.13%），低频范围内的声压级也有所降低。所建议的材料成分和工艺方法显示了制造轻质、结构高效的大型机身部件的潜力。

Vibro-acoustic characterization of Functionally Graded Multiwalled Carbon Nanotube composite cylindrical panels: An experimental approach

This study experimentally investigates the vibro-acoustic properties of Functionally Graded Multiwalled Carbon Nanotubes (FG-V MWCNT) Glass Fiber Reinforced Polymer composite cylindrical panels, a topic often explored through numerical methods. A novel process methodology is introduced to realize FG-V MWCNT composites, and the results are compared with those of uniformly distributed and conventional composites. Using an in-house developed experimental setup, the natural frequencies, mode shapes, acceleration, and Sound Pressure Levels (SPL) are measured. The FG-V MWCNT composites demonstrate a notable enhancement in fundamental frequency (21.13%) and a reduction in SPL in the lower frequency range compared to conventional composites. The proposed material composition and process methodology show potential for creating lightweight, structurally efficient large airframe components.

期刊介绍： Composites Part A: Applied Science and Manufacturing is a comprehensive journal that publishes original research papers, review articles, case studies, short communications, and letters covering various aspects of composite materials science and technology. This includes fibrous and particulate reinforcements in polymeric, metallic, and ceramic matrices, as well as 'natural' composites like wood and biological materials. The journal addresses topics such as properties, design, and manufacture of reinforcing fibers and particles, novel architectures and concepts, multifunctional composites, advancements in fabrication and processing, manufacturing science, process modeling, experimental mechanics, microstructural characterization, interfaces, prediction and measurement of mechanical, physical, and chemical behavior, and performance in service. Additionally, articles on economic and commercial aspects, design, and case studies are welcomed. All submissions undergo rigorous peer review to ensure they contribute significantly and innovatively, maintaining high standards for content and presentation. The editorial team aims to expedite the review process for prompt publication.
