“…Applications on the interior of the building could be conducted by installing a diffuser-absorber as illustrated in Figure 14a-c. The use of diffuser-absorber in Figure 15 is briefly similar to that in the study of Echeverria et al, Carbajo et al,Dupont et al,and Romadhona et al [33,43,44,54]. In their research, the observed materials had sound absorbing ability at low frequencies.…”

“…Although having low absorption in the middle frequencies (0.4-2.5 kHz) and higher absorption in higher frequencies, 2.5-6.4 kHz, this material indicated an absorption peak of 0.78 in the prototype with less filler matrix. The HFRC with less filler matrix could be used for building elements, especially for urban settlements which are disturbed by urban noise hazards [44]. The results show that the 15 mm Placuna placenta composite with STCT has its peak at 0.42 at 0.9 kHz, while the 30 mm one has its peak at 0.81 at 1.9 kHz.…”

“…As in the previous discussion, these types of diffusers are very good to absorb sound energy at 3.0 kHz and 6.0 kHz. [40,43,44,55], the middle to high frequencies ability on the sound absorption occurred due to the cavities and viscous damping effects. These findings are suitable for acoustical materials for the buildings interior.…”

“…Many studies discussed perforated and micro perforated panels [40,[42][43][44][45]. For example, inhomogeneous perforated with various cavity depth panels was performed by Mosa et al Dividing into two sub areas, the sample has various hole diameters, perforation ratio and is supported with back cavity.…”

On the Role of Acoustical Improvement and Surface Morphology of Seashell Composite Panel for Interior Applications in Buildings

This manuscript focuses on the acoustical behaviors and surface morphology of seashell waste filler reinforced polyester (SFRP) coverings Anadara granosa Linn, Perna viridis Linn, and Placuna placenta Linn and applications in buildings. Their acoustical performances were observed using an impedance tube using a technique with two and four microphones based on ASTM E1050-98 and ASTM E2611-09. The improvements of acoustical performance were conducted by a coupled resonator inclusion with addition of a fibrous dacron layer and back cavity. The experimental results showed that the resonators and back cavity on the material structure were able to shift the absorption ability at low frequency. The promising wide broadband frequencies performance occurred when the 15 mm Placuna placenta FRP treated with front-tailed cavity without any additional fibrous layer and air gap started from 0.2 at 2.0 kHz. The combination of resonators and fibrous layer on the material structure was able to stabilize the sound transmission loss (STL) in 52–56 dB at a high frequency. On the observation of the simple surface morphology material, it was found that Placuna placenta Linn had the highest damping performances due to the smallest pores and the most carbon compound compared to the others. Therefore, this finding is very useful for building applications.

“…As time progressed in the modern age, humans were not satisfied with the available materials as some desirable characteristics of products cannot be satisfied by monolithic materials. Beside the product characteristics, economic requirements and the drive for miniaturization are compelling factors that promoted the gradual transition from monolithic to composites (Tasdemir and Kiziltas, 2009;Sharma et al, 2018;Zhao et al, 2019;Panaitescu et al, 2019;Henning et al, 2019;Echeverria et al, 2019). The miniaturization movement objectively drove progress in composite development from macrocomposite fabrication to micro-composite development.…”

Optimisation of Water Absorption Parameters of Dual-Filler Filled Composites Using Taguchi and Moderated Taguchi Techniques

2019

This work contributes two novel modified Taguchi techniques to the optimal parametric setting for minimum water absorption in epoxy composites. Taguchi method, using ASTM standards was applied with factors (initial weight, final weight, length, sample thickness and time of immersion) and four levels in the experimental design. The analysis of variance (ANOVA) evaluates the significance and individual contributions of the parameters. The optimal parametric setting was A1B4C3D4E1 (initial weight, 2.61 g; final weight, 2.69 g; length, 62.73 mm; thickness, 3.88 mm; time, 15.65 hrs). The ANOVA identifies time and length as dominant parameters (98.98 and 1.02 % contributions, respectively). Taguchi-Pareto analysis found only factor-level from the time and length parameters economical to optimality. The Taguchi-ABC analysis revealed the individual weights and contributions of the factor-level irrespective of its initial groupings. The new Taguchi techniques highlighted the importance of time and length of sample in obtaining minimum water absorption of composites.

Effect of hybridization on natural fiber reinforced polymer composite materials – A review

2023

View full text Add to dashboard Cite

This review explores the hybridization effect of natural fiber‐reinforced composites (NFRCs) to reduce energy consumption and environmental pollution. Although natural fibers offer several advantages over synthetic fibers, such as biodegradability, lightweight, and low cost, their application in NFRCs is challenging due to inherent issues such as variable fiber quality, constrained mechanical properties, water absorption, and poor thermal stability. However, recent research has made significant progress in addressing these issues, resulting in better NFRCs. This article surveys the latest developments in plant‐based NFRCs, focusing on methods and innovations to enhance their performance through fiber modification, hybridization, incorporation of lignocellulosic fillers, and fabrication techniques for mechanical, sound absorption, and wear performance. It also discusses the expanding uses of NFRCs in various industrial sectors and the sustainability of plant‐based NFRCs using life‐cycle assessment.
