摘要

低频噪音是工业领域常见的工程问题。本研究利用石墨颗粒来显著增强碳纤维层压板的低频隔音效果。通过理论和实验研究了不同质量和网格的石墨颗粒对层压板隔音性能的影响。基于 Galerkin 方法提出了层压板运动方程的分析模型。利用 Halpin-Tasi 模型和混合规则计算了样品的有效弹性特性。准备了两组样品用于隔音测量。理论与实验结果的对比表明，理论可以很好地预测纳米粒子增强层压板的隔音效果。在不改变层压板厚度的情况下，低频透声损失可明显改善 3-8 dB。不过，石墨颗粒的网格变化对层压板的隔音效果影响不大。

An advanced nanoparticle reinforced carbon fiber laminates for low frequency sound insulation

Low frequency noise is a common engineering problem in the industrial field. This study utilizes graphite particles to enhance the low frequency sound insulation of carbon fiber laminates significantly. The effects of grasphite particles with different mass and mesh on sound insulation of laminates are investigated by theory and experiment. The analytical model is proposed based on the Galerkin method for the laminates’ motion equations. The effective elastic properties of the samples are calculated using the Halpin-Tasi model and the rule of mixture. Two groups of samples are prepared for sound insulation measurement. The comparison between the theoretical and experimental results shows that the theory can well predict the sound insulation of the nanoparticle reinforced laminates. A significant improvement in low-frequency sound transmission loss of 3–8 dB is achieved without altering the laminates' thickness. However, the mesh variation of the graphite particles has little effect on the sound insulation of laminates.

期刊介绍： Composites Communications (Compos. Commun.) is a peer-reviewed journal publishing short communications and letters on the latest advances in composites science and technology. With a rapid review and publication process, its goal is to disseminate new knowledge promptly within the composites community. The journal welcomes manuscripts presenting creative concepts and new findings in design, state-of-the-art approaches in processing, synthesis, characterization, and mechanics modeling. In addition to traditional fiber-/particulate-reinforced engineering composites, it encourages submissions on composites with exceptional physical, mechanical, and fracture properties, as well as those with unique functions and significant application potential. This includes biomimetic and bio-inspired composites for biomedical applications, functional nano-composites for thermal management and energy applications, and composites designed for extreme service environments.
