“…As it can be seen in Figure 4, the flexural strength of hybrid composite J25:P75 is found 82.26 MPa which is 83.6%, 91.3%, 94.4%, and 98.9% more as compared to those of composites J100:P0, J75:P25, J50:P50, and J0:P100, respectively. Previous reports stated that weight percentage of palm leaf fiber shows dislocation of tightly packed fiber and matrix stickiness [23]. Nonhybrid palm leaf and jute fiber-reinforced composites demonstrated the lowest flexural strength, respectively, with compared to hybrid composites.…”

Hybrid composites have proven endless benefits to the research communities in terms of environmental friendliness, mechanical properties, and development of new material. The present work explores the tensile, flexural, impact strengths, and water absorption properties of jute and palm leaf fiber-reinforced hybrid composites. Five types of hybrid composites were fabricated by varying jute and palm leaf fiber percentage of J100:P0, J25:P75, J50:P50, J25:P75, and J0:P100% with a constant weight ratio of polypropylene matrix. The findings showed that jute-palm leaf fiber-reinforced composite had positive effect on tensile, flexural, and impact strength. Experimental results showed that the J25:P75% (jute and palm leaf fiber) exhibited the highest tensile strength of 62.2 MPa and flexural strength of 82.26 MPa due to the optimal interfacial properties between the fibers and matrix. The impact strength of composites increased as the proportion of palm leaf fiber increased. Water absorption increased with jute fiber content, reaching a maximum of 1.26% at composite J100:P0, with lower water absorption at J0:P100% composite due to the higher moisture content of jute fiber.

“…Dhandapani and Megalingam reported that the tensile, flexural, and impact strength of sisal/palm fiber-reinforced hybrid composites increased as palm fiber content rose due to the tight link between the matrix and the fibers [23]. Jute and oil palm leaf are abundant, according to the researchers.…”

“…Due to the greater weight proportion of palm fiber (65% epoxy resin, 20% sisal fiber, and 15% palm) in the composite, it rendered a high SAC at frequencies of 1600 Hz, 2000 Hz, 2500 Hz, 3150 Hz, and 4000 Hz. Above that, the above hybrid composite exhibited a maximum SAC difference of 76.61% in comparison to the other three hybrid composites at a frequency of 4000 Hz [ 114 ].…”

Increasing global environmental problems and awareness towards the utilization of eco-friendly resources enhanced the progress of research towards the development of next-generation biodegradable and environmentally friendly material. The development of natural-based composite material has led to various advantages such as a reduction in greenhouse gases and carbon footprints. In spite of the various advantages obtained from green materials, there are also a few disadvantages, such as poor interfacial compatibility between the polymer matrix and natural reinforcements and the high hydrophilicity of composites due to the reinforcement of hydrophilic natural fibers. This review focuses on various moisture-absorbing and sound-absorbing natural fiber polymer composites along with the synopsis of preparation methods of natural fiber polymer composites. It was stated in various studies that natural fibers are durable with a long life but their moisture absorption behavior depends on various factors. Such natural fibers possess different moisture absorption behavior rates and different moisture absorption behavior. The conversion of hydrophilic fibers into hydrophobic is deemed very important in improving the mechanical, thermal, and physical properties of the natural-fiber-reinforced polymer composites. One more physical property that requires the involvement of natural fibers in place of synthetic fibers is the sound absorption behavior. Various researchers have made experiments using natural-fiber-reinforced polymer composites as sound-absorbing materials. It was found from various studies that composites with higher thickness, porosity, and density behaved as better sound-absorbing materials.

“…This is mainly due to the increase in fiber matrix bonding and the removal of foreign substituents. Dhandapani and Megalingam 6 experimentally investigated the mechanical and sound characteristics of sisal/palm-based NFRHCs. The result revealed that the composites with 65 wt% epoxy resin, 20 wt%sisal, and 15 wt% palm fiber exhibited maximum tensile, flexural, and impact strength.…”

To control the noise pollution through sound absorption, the development of natural fiber-reinforced hybrid composites (NFRHCs) using waste tea leaf fibers (WTLFs) and pineapple leaf fibers as reinforcing materials with epoxy matrix will act as an initial step to address this issue. Also, a minimal additional reinforcement of glass fibers was added for achieving mechanical strength too. The fabricated samples underwent a sound absorption test for assessing their capability of absorbing unwanted noise. With the help of sound absorption coefficient (SAC) curves acquired from the impedance tube method, the effects of the weight fraction and mass densities of WTLF and the thicknesses of the fabricated composites on their sound absorption ability were investigated. From the investigation, it was found that the noise reduction coefficient of the developed NFRHCs was more than 0.7 at a broad frequency spectrum. The fractal dimensions were estimated using the MATLAB program by utilizing the box-counting dimension method to correlate the effects of porosity percentage with weight fractions and mass densities of WTLF and the thicknesses of the fabricated NFRHCs. Following that, a quantitative relationship between the fractal dimension and SACs of the developed NFRHCs was derived to offer a theoretical concept for the future design of similar sound-absorbing materials.
