“…Furthermore, SPCs can be completely melted and when it comes to recycling, this property is a great advantage compared to, for example, carbon or glass fibre reinforced composites, whose mechanical and thermal recycling still causes environmental problems [8]. In the near future, these SPCs and melt-blown fibre mats can significantly contribute to a wide range of applications, for example tissue scaffolds [9], filtering applications [10], superhydrophilic membranes [11,12], sound absorption [13] and ductile & impact-resistant components [14,15].…”

In this study, we generated polypropylene fibre mats via melt blowing (average diameter:1.03 µm), and then produced self-reinforced composites using hot compaction and investigated the effect of the processing temperature. Scanning electron microscopy (SEM) revealed that our composites had good consolidation, low void content and besides, the fibres and the matrix were clearly distinguishable. The differential scanning calorimetry (DSC) tests showed that the composites are easy to recycle by re-melting. The tensile tests of the melt-blown nonwovens and the produced composites revealed that increasing the temperature of hot compaction results in embrittlement (from ductile to brittle) of the samples, which means higher specific tensile forces and smaller deformations. Using the Fibre Bundle Cells modelling method, we developed a phenomenological, analytical model to describe the total tensile curve (both the deformation and the failure behaviour) and analyse the tensile properties of these hot compacted composites. The determination coefficients (R 2 ) between the modelled and measured force were larger than 0.99 and the relative mean squared error (RMSE) values (related to the measured maximum force 2 value) were smaller than 3% in every examined case, which indicated good modelling. Hence, the FBC model not only described the tensile behaviour of the nonwovens well, but it was also applicable for the composites.

“…[ 107,109 ] Changes in the reinforcing architecture of the fibers lead to changes in their acoustic properties. [ 14,17,104,105 ] The coir fiber had a good sound absorption coefficient and transmission loss index value, according to the acoustic property results. The coir fiber's arrangement can be changed to modify the sound absorption capabilities.…”

Noise pollution caused by urbanization and industrial development must be effectively controlled to provide a pleasant living atmosphere. Different synthetic fiber materials have good acoustic performance, yet synthetic fiber materials have a high cost and have adverse effect on the environment. Natural fibers are a good alternative to synthetic fibers in terms of acoustic properties and they are also less expensive and have less environmental impact. Several factors affects the acoustic behavior of natural fiber reinforced polymer composites (NFRPCs). The present article focuses on the effect of different processing methods, reinforcement architecture, fiber diameter, laminate thickness and density on the acoustic performance of NFRPCs. Reinforcement architecture has been proved to be the best option in order to tailor the various acoustic properties of the composite laminates without even changing other physical properties. The challenges, future scope and potential applications of natural fibers in acoustic applications (home theaters, offices, cinema halls, automobiles, etc.) have also been discussed.

“…The study had shown that closedcell polyurethane foams with membranes had better acoustic properties than the open-cell ones with similar parameters in the 500-6000 Hz frequency range. In addition, Tang et al [20] improved sound absorption of layered materials composed of nonwoven fabrics and polymeric membrane by adjusting the layering sequence. A research found that the characteristic absorption peaks shifted to the lower frequency by tuning the layer thickness and thickness ratio of the microlayer foam/film sheet materials [21].…”

Kapok fiber with high degree of hollow and small fiber diameter has excellent sound absorption. To optimize the sound absorption characters at the low frequency, sound absorption coefficients and specific surface impedance of two-layer, three-layer, and four-layer materials as polyethylene film-reinforced kapok fiber nonwoven fabrics have been studied by using the impedance tube method in the frequency range of 100–2500 Hz. The layering sequence, the polyethylene films thickness, and the gradient thickness structure of nonwoven fabrics affected the sound absorption properties at the low frequency for multi-layer materials that have been analyzed. The results show that the multi-layer composite materials have better sound absorption than a single-layer nonwoven fabrics at the low frequency. The elastic vibration of polyethylene film contributes to sound absorption improvement at the low frequency. The sound absorption at the low frequency of multi-layer materials can be further improved by changing polyethylene film position or increasing polyethylene film thickness. In addition, the gradient thickness structure of nonwoven fabrics can effectively improve sound absorption at the low frequency, and the gradient change direction also exhibits remarkable effects on the sound absorption of multi-layer materials.
