“…Enhancing the environmentally friendly composites, LNFCs have a solid potential to be involved in several vibration and sound isolation utilizations, such as in yachts, cars, and airplanes, due to their high elastic properties and damping [89,[125][126][127][128][129]. Pure luffa fibers have a significant sound absorption coefficient, which indicates that thick, pure luffa specimens can result in better acoustic properties [87].…”

Natural fiber composites (NFCs) are an evolving area in polymer sciences. Fibers extracted from natural sources hold a wide set of advantages such as negligible cost, significant mechanical characteristics, low density, high strength-to-weight ratio, environmental friendliness, recyclability, etc. Luffa cylindrica, also termed luffa gourd or luffa sponge, is a natural fiber that has a solid potential to replace synthetic fibers in composite materials in diverse applications like vibration isolation, sound absorption, packaging, etc. Recently, many researches have involved luffa fibers as a reinforcement in the development of NFC, aiming to investigate their performance in selected matrices as well as the behavior of the end NFC. This paper presents a review on recent developments in luffa natural fiber composites. Physical, morphological, mechanical, thermal, electrical, and acoustic properties of luffa NFCs are investigated, categorized, and compared, taking into consideration selected matrices as well as the size, volume fraction, and treatments of fibers. Although luffa natural fiber composites have revealed promising properties, the addition of these natural fibers increases water absorption. Moreover, chemical treatments with different agents such as sodium hydroxide (NaOH) and benzoyl can remarkably enhance the surface area of luffa fibers, remove undesirable impurities, and reduce water uptake, thereby improving their overall characteristics. Hybridization of luffa NFC with other natural or synthetic fibers, e.g., glass, carbon, ceramic, flax, jute, etc., can enhance the properties of the end composite material. However, luffa fibers have exhibited a profuse compatibility with epoxy matrix.

“…Design and development of new biomaterials as an alternative to chemical-based materials such as glass and carbon fibers has become a necessity due to the adverse effects of chemical materials on people and nature (Selonen et al 2020). Due to their sustainability and low cost (Kalauni and Pawar 2019), biomaterials appear to be a very promising alternative to chemical-based materials (Bansod, Mittal, and Mohanty 2016;Berardi, Iannace, and Di Gabriele 2017;Gokulkumar et al 2019;Koruk and Genc 2019;Takagi 2019). As the mechanical properties of biomaterials are not as good as those of chemical materials (Gurunathan, Mohanty, and Nayak 2015;Taha and Ziegmann 2006), it is necessary to develop, test and optimize different configurations of biomaterials before they are considered for practical applications.…”

“…Various methods have been used for mechanical characterization of biomaterials in the literature (Arulmurugan et al 2019a(Arulmurugan et al , 2019b(Arulmurugan et al , 2020Koruk and Genc 2019;Prabu, Rajamurugan, and Thirumurugan 2019). In addition to classical characterization methods such as tensile testing, experimental modal analysis can also be used for the identification of damping and elastic properties of materials (Koruk and Genc 2019). For the determination of the acoustic properties of biomaterials, the impedance tube method is widely used (Berardi and Iannace 2015;Koruk and Genc 2015).…”

“…where ρ 0 is the air density and f shows the frequency. The Young's modulus of the luffa composite plates with similar fiber/epoxy ratios is around 2 GPa (Koruk and Genc 2019;Saygili et al 2020). Hence, the critical frequencies for the 15-20 mm thick luffa plates using Eqs.…”

“…Among many natural fibers, the natural material jute is the most produced one worldwide (Perumal et al 2018). Another natural material, luffa, which is grown in many regions in the world, has attracted considerable attention from engineers and researchers in recent years (Alhijazi et al 2020;Koruk and Genc 2019). It is noted that jute has superior mechanical properties, high sound absorption coefficients (SACs), and transmission losses (TLs) (Bansod, Mittal, and Mohanty 2016;Ramesh, Palanikumar, and Reddy 2013), while luffa has high damping and SACs (Koruk and Genc 2015).…”

The acoustic properties of natural fiber-reinforced composites should be identified before using these materials in various engineering applications including sound and vibration isolation. This study investigates the effects of sample thickness and fiber/resin ratio on the acoustic performance of jute and luffa fiber-reinforced biocomposites. For this purpose, jute and luffa composite samples with different thicknesses and fiber/epoxy ratios are manufactured and their sound absorption coefficients (SACs) and transmission losses (TLs) are determined using impedance tube method. Thicknessdependent tendencies of the SACs and TLs of jute and luffa composites for low-, medium-, and high-frequency ranges are identified. The effect of fiber/ epoxy ratio on the acoustic properties of jute and luffa composites as a function of frequency are determined. Furthermore, the SACs and TLs of some natural fiber-based samples with different thicknesses are predicted using mathematical models and the theoretical and experimental results are compared and evaluated.
