“…Generally, we use the sound absorption coefficient to quantify the sound absorption performance of the materials, which is the ratio of absorbed acoustic energy and incident acoustic energy. 26 Normally, the material could be called a sound absorption material when the sound absorption coefficient exceeds 0.2, 27 and it can be considered to have high sound absorption performance when the sound absorption coefficient is greater than 0.56. 28 The equipment we used to analyze the sound absorption performance of the composite structure in the frequency range of 100 Hz to 2.5 kHz is shown in Figure 5c.…”

Chemical fibers such as glass fiber and aramid cover a large proportion of sound-absorbing composite materials on the current commercial market. These materials possess superior mechanical properties but have the disadvantages of high production costs and energy consumption and difficult recovery and degradation. In this paper, jute fiber and polypropylene were selected as raw materials, and a series of jute fiber-reinforced polypropylene composite materials were prepared by a mixing-hot-pressing process. The acoustic and mechanical performances of the composites with different fiber contents and fiber residue ratios were discussed. The results showed that the sound absorption coefficient values increased with the increasing fiber content and decreasing residual gum ratio. The mechanical properties varied inversely with the residual gum rate. With the increase of fiber content, the tensile and bending strengths first increased and then decreased. Therefore, the jute fiber-reinforced polypropylene composites can possess favorable sound absorption performance with no mechanical property penalty by adjusting the parameters properly, demonstrating that the composite materials have promising applications in the acoustic field.

Ceramic nanofibers (NFs) have recently been developed for advanced applications due to their unique properties. In this article, we review developments in electrospun ceramic NFs with regard to their fabrication process, properties, and applications. We find that surface activity of electrospun ceramic NFs is improved by post pyrolysis, hydrothermal, and carbothermal processes. Also, when combined with another surface modification methods, electrospun ceramic NFs result in the advancement of properties and widening of the application domains. With the decrease in diameter and length of a fiber, many properties of fibrous materials are modified; characteristics of such ceramic NFs are different from their wide and long (bulk) counterparts. In this article, electrospun ceramic NFs are reviewed with an emphasis on their applications as catalysts, membranes, sensors, biomaterials, fuel cells, batteries, supercapacitors, energy harvesting systems, electric and magnetic parts, conductive wires, and wearable electronic textiles. Furthermore, properties of ceramic nanofibers, which enable the above applications, and techniques to characterize them are briefly outlined.

Noise is considered severe environmental pollutant that affects human health. Using sound absorption materials to reduce noise is a way to decrease the hazards of noise pollution. Micro/nanofibers have advantages in sound absorption due to their properties such as small diameter, large specific surface area, and high porosity. Electrospinning is a technology for producing micro/nanofibers, and this technology has attracted interest in the field of sound absorption. To broaden the applications of electrospun micro/nanofibers in acoustics, the present study of electrospun micro/nano fibrous materials for sound absorption is summarized. First, the factors affecting the micro/nanofibers’ sound absorption properties in the process of electrospinning are presented. Through changing the materials, process parameters, and duration of electrospinning, the properties, morphologies, and thicknesses of electrospun micro/nanofibers can be controlled. Hence, the sound absorption characteristics of electrospun micro/nanofibers will be affected. Second, the studies on porous sound absorbers, combined with electrospun micro/nanofibers, are introduced. Then, the studies of electrospun micro/nanofibers in resonant sound absorption are concluded. Finally, the shortcomings of electrospun micro/nano fibrous sound absorption materials are discussed, and the future research is forecasted.
