“…[26] Meanwhile, the low result on sound absorption coefficient of ST SCB is probably due to a tighter pack fiber in the composite. In comparison between these current studies with previous investigations, [35] analysis found that the result contrasted which means that untreated sorghum stalks bagasse are more effective in high sound absorption coefficient compared to treated sorghum stalks bagasse. This effect is most likely caused by natural fiber surface pre-treatment, which reduces fiber diameter and hollow lumen structure as moisture content is removed, reducing acoustic absorption performance.…”

“…The majority of previous studies agreed that this was most likely due to the thermal decomposition of hemicellulose, lignin, pectin, and glycosidic linkages of cellulose in natural fibers. [34] In contrast to previous research, the weight reduction divergence intervening plain [35] and treated hybrid composites could be attributed to silane treatment removing lignin and hemicellulose addition, the cellulose was disclosed by silane treatment and silane layer on fibers, resulting in enhanced thermal stability due to improved interfacial bonding. [36] The ultimate thermal decomposition phase of ST OPEFB, ST SCB, and STOPEFB:STSCB hybrid composites exist at 420 C, with weight losses ranging from 15% to 18%, most likely due to complete thermal disintegration of cellulose and depolymerization of the phenolic matrix in composites itself.…”

The consequence of 2% v/v silane-treated and 4% v/v H 2 O 2 -treated upon thermal and acoustic behavior of hybrid oil palm EFB (OPEFB) and sorghum stalks bagasse fiber (SCB) reinforced phenolic composites for wall thermal insulation application is discussed in this paper. Hand lay-up approach was adopted to manufacture plain and hybrid composites with diverse formulation ratios such as 70:30 (7OPEFB:3SCB), 50:50 (5OPEFB:5SCB), and 30:70 (3OPEFB:7SCB). The experimental samples were manufactured with a purpose density of 0.5 g/cm 3 . Plain and hybrid composites were investigated for thermal analysis and thermal conductivity testing. Impedance tubes were used for acoustic behavior analysis of composites. Hybridization of H 2 O 2 treated HT 50:50 (5OPEFB:5SCB) showed greater thermal cohesion with a final residual of 58.69%, followed by hybridization of silane-treated ST 50:50 (5OPEFB:5SCB) with a residual of 45.10%. This study looks at four distinct air gap thicknesses (0 mm, 10 mm, 20 mm, and 30 mm). The results reveal that silane-treated ST 50:50 (5OPEFB:5SCB) hybrid composites and H 2 O 2 -treated HT 50:50 (5OPEFB:5SCB) hybrid composites improved sound absorption coefficients more than 0.50. Thus, we concluded that thermal and sound absorption performances of hybrid composites from agro waste promise an environmentally friendly alternative solution in wall building material production.acoustic properties, biophenolic resin, hybrid composites, oil palm EFB fibers, sorghum stalks bagasse fiber, thermal properties | INTRODUCTIONAccording to recent research studies, green composites made of natural fibers have always piqued the interest of researchers and industrial sectors as a result of their excellent mechanical and physical properties, thus increased stability and stiffness, improved sustainability, biodegradability, lightweight, safe, and easy processing.

Natural fiber reinforced polymer composites (NFRPCs) have emerged as promising eco‐friendly alternatives over conventional synthetic fiber composites due to their inherent biodegradability, renewability, low environmental impact, and lightweight properties. It has been seen a significant growth in both invention and innovation in the field of NFRPCs. Natural fibers (NFs) reduce the cost of the material by 5%, the weight of the composite by 10%, and the energy required for production by 80%. In terms of thermal, and acoustic properties, NFs can successfully compete with synthetic fibers. As a result, the development of NFRPCs for industrial use has increased significantly in the past decade to meet the growing demands of industrial sectors. To improve the thermal and acoustic properties of NFRPCs, researchers have done a lot of investigation. The aim of the current review is to provide a comprehensive analysis of the existing literature on the thermal and acoustic properties of natural fiber reinforced polymer composites. Thermal properties such as thermal conductivity, TGA, DSC, DMA, and acoustic properties of natural fiber reinforced composites with several parameters, such as different fiber types, different matrix types, fiber weight ratio, fiber to matrix ratio, chemical treatment of fiber have been summarized and analyzed very concisely. This review also emphasizes a summary of different natural fibers, their chemical compositions, composite preparation, characterizations, and future research directions. This article enables the readers, researchers, and manufacturers to realize several opportunities about the latest developments in NFRPCs for the application of thermal and acoustic purposes.Highlights Natural fibers can successfully compete with synthetic fibers, in terms of thermal and acoustic properties. Thermal properties of natural fiber reinforced composites including thermal conductivity, TGA, DSC, and DMA are summarized. Acoustic properties of natural fiber reinforced polymer composites are discussed. Composite materials made of treated fibers result better thermal stability than untreated fiber composites. Sound absorption coefficient generally increases as fiber content increases.
