Original publication title: Effect of mesh sizes on the vibrational and acoustic properties of stainless-steel wire mesh/glass fiber reinforced hybrid composite laminates.
Plain-English summary
This study looked at how different sizes of openings in stainless-steel wire mesh affect the way glass fiber-reinforced polymer laminates vibrate and sound. The researchers created square laminates and tested them for their ability to vibrate and absorb sound. They found that the mesh with 40 openings per inch was best for stiffness and high-frequency sounds, while the mesh with 120 openings per inch was better for reducing low-frequency noise and vibrations. Overall, the findings suggest that using the right mesh size can help improve the performance of materials in situations where strength and sound control are important.
Abstract
This research examines how stainless-steel wire mesh (SSWM) openings (10, 20, 40, 80, 120 openings per inch) impact the vibrational and acoustic behavior of glass fiber-reinforced polymer (GFRP) hybrid composite laminates. Laminates (300 mm × 300 mm) were prepared by compression molding with a [GF<sup>0°</sup>/GF<sup>0°</sup>/GF<sup>0°</sup>/SSWM<sup>0°</sup>/GF<sup>0°</sup>/GF<sup>0°</sup>/GF<sup>0°</sup>] stacking sequence. Vibration tests, performed according to ASTM E756-05, showed that mesh 40 had the highest natural frequency (16.38 Hz), stiffness coefficient (232.51 N/m), and storage modulus (134.22 GPa), which were promoted by optimal mesh opening size (0.361 mm) and SSWM mass (116.8 g). Finer meshes (80, 120) improved damping ratios (up to 0.17 for mesh 120, an increase of 450% over mesh 40's 0.03) owing to decreased stiffness and greater interfacial friction. Impedance tube measurements according to ISO 10534-2 indicated mesh 120 with better low-frequency transmission loss (9.24 dB mean, 15.23-16.53 dB at 67-90 Hz) because of its thin laminate (1.19 mm) and low SSWM mass (35.7 g). In contrast, mesh 40 performed best at high frequencies (15.85 dB mean, 23.56 dB at 6300 Hz). These results demonstrate the appropriateness of mesh 40 for stiffness-critical applications and mesh 120's effectiveness for vibration damping and low-frequency noise reduction, and provide customized solutions for structural and acoustic performance in high-risk scenarios.
