“…The same trend in the results was obtained with the addition of nanofillers. [ 6,51 ] The variations in the elastic modulus are illustrated in Figure 4 and the increasing trend in elastic modulus is observed with the increase of the nanofiller. The same trend in the results for the elastic modulus was observed with the addition of the nanofiller.…”

The mechanical, ballistic, and moisture intake properties of luffa fiber reinforced with graphene-modified epoxy composites were experimentally investigated. The nanofiller graphene particles were modified with a matrix using the mechanical stirring process. The filler (graphene) of size 20 nm is modified with the matrix of different weight percentages 0, 1, 2, 3, and 4. The samples for various testings were prepared with different compositions using a hand layup technique followed by compression molding. The results show that tensile, impact, and flexural strength were enhanced with the modification of the filler graphene up to 2 wt%. The ballistic impact results show that energy absorption increases with nanofiller modification. Minimum water intake behavior is observed for the composite samples incorporated with fillers. Failure mechanisms were studied on tensile tested specimens using a scanning electron microscopy. The morphological images showed defects like interfacial behavior, fiber pull out, voids, and internal cracks on the tested specimens.

[1] As the world is focusing on reducing the effect of greenhouse gasses in the atmosphere, the demand for using natural fibers as reinforcements increased. [2,3] Inorganic fibers like carbon, aramid, and glass fibers have good attractive properties that make them ideal for use as reinforcements in polymer composites. [4] Nevertheless, synthetic fibers suffer from nonbiodegradability, high cost, and hazardous gasses during disposal, which made researchers find new alternative materials. [5] Hence, they tried to use natural fibers as alternative materials to overcome the problems of using synthetic fibers. [4,6] Natural fibers like sisal, [7] banana, [8-11] jute, [12-14] coir, [15,16] luffa, [17,18] hemp [19] and flax, [9,20] and so forth are most commonly used as reinforcements in polymer composites and those materials were used in various interior applications such as furniture, acoustics, vibration isolation, packaging, automobile industries, aeronautical, and marine sectors. [21,22] Their hydrophilic nature reduced compatibility, reinforcing effect, and stress transfer with polymer matrices made the natural fiber composites fit for use in light load and interior applications. The properties and quality of composites depend on the degree of compatibility between the matrix and natural fiber. [23-25] To enhance the bonding between the matrix and fibers researchers used different methods, one of which is surface treatments. Generally, surface treatments like alkali, [3,6,26-28] silane, [29,30] benzoylation treatment, [6,31] and so forth are used for treating the fiber surface. Tolera A. Negawo et al [32] studied the influence of alkali

“…It improved the compatibility between filler and polyester matrix [29]. Apart from that, natural fillers such as calotropis gigantean stem powder, azadirachta indica seed powder, spent camellia sinensis powder along with graphene powder was used for enhancing the properties of natural fiber composites [30][31][32]. In Southern part of India especially in Tamilnadu production of banana, sugar cane and coconut tree are plenty.…”

This research was based on influence of various fly ash filler content in the machining properties of Pineapple (P)/Sisal (S) hybrid fiber reinforcement composites. Fly ash from bio waste materials of Bagasse (BGFA), Banana (BFA) and Coir (CFA) were used. High hardness nature of 3% BFA (22.73 HV) and 3% CFA (23.85 HV) reduces Material Removal Rate (MRR) and increases its surface roughness nature of the composites. Maximum MRR of 376.38 mm 3 min −1 was observed in 3% BGFA combinations with 250 MPa Water jet Pressure (WP), 1mm Standoff Distance (SOD) and 20 mm min −1 Traverse Speed (TS) as machining parameters. MRR of 353.64 and 352.76 mm 3 min −1 was found out with 1% CFA and 1% BFA combinations. Lower surface roughness of 6.39 μm, 6.71 μm and 6.75 μm was found in 3% BGFA, 1% CFA and 1% BFA based composites. Filler surface created a tight bonding with the matrix, which reduces the erosion of fiber particles at higher WP. Untreated fibers showed lesser machining properties due to low fiber/matrix bonding. SEM results showed reducing of cracks and matrix breakages by the substitution of filler powders.

“…Techniques such as vacuumassisted resin transfer molding, compression molding, resin transfer molding, pultrusion, injection molding, and pressure bag molding are used to fabricate thermosetbased composites. [14,15] The thermoplastic-based composites are prepared by using the filament winding, extrusion, thermoforming, injection molding, compression method, foam molding, cold pressing, and co-extrusion techniques. [16][17][18] This review provides information about the properties of some newly identified natural fibers, types of nano-clay and recent progress in the development and characterization of nano-clay added natural fiber composites with specific concern to their mechanical properties.…”

The utilization of sustainable natural fibers as green filler/reinforcement material for producing polymeric composites is substantially improved due to increase in the perception of ecological safety and usage of biodegradable and renewable materials toward a green environment. These natural fibers are obtained from various sources and are reinforced in the polymer matrices to produce polymer matrix composites. However, the overall properties of these composites are low when compared to that of the synthetic fiber-based composites due to poor interfacial bonding between the hydrophilic natural fiber and hydrophobic polymers. This deficiency can be addressed by incorporating
