“…The tensile modulus of the CF-2 and CF-3 is found to be 358.33 MPa and 550 MPa, respectively, the increase in the tensile modulus in CF-3 is because the alkali treatment has increased the surface roughness of the fillers, thus enhancing the bonding between the fiber filler and matrix. The presence of fillers always enhance better results, and this was in accordance with the literature [30].…”

The current study deals with the effective usage of Portunus sanguinolentus shell, which is a solid waste in the seafood industry. This Portunus sanguinolentus shell waste was powdered and used as untreated fillers in jute fabrics reinforced epoxy composites. Then Portunus sanguinolentus shell waste powder was treated with chemicals to perform fat removal, deproteination, decarbonization and deacetylation to obtain treated Portunus sanguinolentus shell filler. Three different composites were developed with traditional hand layup process consisting of four layers jute fabrics that were filled with 10 wt% untreated Portunus sanguinolentus shell filler, chemical treated 10 wt% Portunus sanguinolentus shell filler and unfilled one. The thermo-mechanical and fracture morphologies were assessed by tensile, flexural, compression, shear, impact, hardness thermogravimetric analysis, Fourier-transform infrared spectroscopy and scanning electron microscopy analysis. The results showed an increase in the thermo-mechanical property of chemical-treated Portunus sanguinolentus shell powder-filled jute fabrics-based epoxy composite. This phenomenon is due to the increase in the chitosan, mineral contents and decrease in the organic content in the Portunus sanguinolentus shell powder due to chemical treatment, thus enhancing the bonding between the filler and fiber matrix with reduction of the void. A showcase stand was developed with the best performer, as an attempt in the perfection of application. The application is then analyzed using ANSYS to predict the deformation behavior when subjected to 0.25 kg, 0.5 kg and 1 kg loads.

“…voids filled with fillers) present in JC-3 results in improved impact strength [45,46]. It is said in some literature that brittleness in the composite reduces the results, but in the current study, it is contradictory due to better interaction with the matrix [47,48]. Similarly, JC-4 composites that are filled with an equal weight percentage of two fillers have exhibited second highest results among the tested composites.…”

“…JC-3 has showed better hardness due to the presence of finer and uniform shaped Azadirachta indica seed powders, which get distributed in the matrix uniformly by reducing the void contents forming fibre–filler–matrix interface (cross-linking nature causing matrix immobility). In the case of JC-2, irregular particles form partially filled voids leading to the lower hardness properties [47,48]. In the case of JC-1, the voids are predominant, which causes poor hardness.…”

The present work examined the thermo-mechanical characteristics of bio-fillers, namely Azadirachta indica seed powder, spent Camellia sinensis powder, their combinations filled jute fabrics–epoxy composites analytically and experimentally and compared it with the unfilled one. The test results showed that Azadirachta indica seed powder filled composites showed better mechanical properties with lesser voids, while spent Camellia sinensis powder and its composites showed better thermal stability. ANSYS analysis was used to show the stress distribution during the tensile and flexural testing. Scanning electron microscopy was used to study various characteristics of the fractured composites. A telephone stand was also fabricated to prove the application capability of best mechanical performer and analysed for deformation behaviour.

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
