“…The length of a luffa sponge is around 15 to 25 cm. [3,4,27,42] The content of cellulose in the luffa fiber varies from 55 to 90 wt%, the content of lignin varies from 10 to 23 wt%, and the content of hemicelluloses varies from 8 to 22 wt%. The luffa fiber has extractive and ash content of 3.2 and 0.4 wt%.…”

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

The effects of alkali treatment and dune sand (DS) addition on the mechanical, morphological, thermal and water absorption behavior of date palm fiber (DPF) reinforced unsaturated polyester (UP) composites were investigated. The composites were synthesized by hand lay-up method with 10, 20, and 30 wt% of both treated and untreated date palm fiber (TDPF/DPF). Furthermore, composites having 10, 20 and 30 wt% of untreated date palm fiber and dune sand (both of them were in equal wt%) were also fabricated. Alkali treatment improved the tensile strength, tensile modulus, flexural strength and flexural modulus of the resulting composites. Scanning electron microscopy (SEM) revealed the better interfacial interaction of treated date palm fibers/UP composites. Thermogravimetric analysis (TGA) showed that thermal stability, and degradation temperature of treated DPF composites were best over the untreated DPF composites. Water absorption test indicated the decreasing of hydrophilic character of the filler after treatment with sodium hydroxide (NaOH). Overall analysis represented that satisfactorily improved physical properties of UP for various engineered and hi-tech applications were obtained with 10 wt% fillers loading (5 wt% date palm fiber and 5 wt% dune sand particles).

“…Based on service preferences, it plays a vital role in selecting the top ranked alternative and correlates it with all ranks in all sets of simulations. It is a multi‐criteria decision analysis method which provides more practical results and that is why it finds its applications in composite materials to determine the ranking according to the service requirements based on the relative weightage of one or more physical, mechanical, thermal, and chemical properties . In this paper, TOPSIS technique has been successfully used to position the composites on the premise of relative closeness to the positive ideal solution based on the output constraints infers that physical, mechanical and wear properties.…”

Silver nanoparticles/polymer composite (Ag‐NPs/PC) may eventually be biodegradable, sustainable, or burned without production of lethal by‐products and can be utilized as packaging and biomedical device applications. Nanoparticles engaged in pine gum (resin and rosin) are preserved for months without any significant effect on particle size and distribution. This paper focuses on the pine gum/epoxy composites with and without silver nanoparticles fabricated by a hand lay‐up technique. Silver nanoparticles are fixed at 0.37% and pine gum varies from 2 to 24% by weight to acquire the best mechanical and wear properties. The result indicates that Ag‐NPs with pine gum (23.7 wt% resin &13.3 wt% rosin) has the best tensile and impact strength reaching a gain of 51.34% and 53.68% simultaneously. Hardness is noted most extreme 17.92% at Ag‐NPs sample (7.4 wt% resin and 3.7 wt% rosin) and wear resist behavior is best noted with neat pine gum/epoxy composite. The antibacterial assay of the Ag‐NPs is done against Escherichia coli and noted that the zone of inhibition is found to be 1.6 cm as compared to inhibition of 0.4 cm for pine gum reaching an advance of 75%. The various arrangements are enhanced and sited on the basis of TOPSIS technique.
