“…In our previous paper, hybrid composite was fabricated using FA, SSL fiber, and PP. [4,5,44] Key finding from this research was moisture mitigation and improved mechanical properties of such hybrid composites compared to pristine PP and composites reinforced with FA and SSL fiber alone. It was also reported that addition of inorganic/ synthetic reinforcement with natural fiber decreases the water uptake tendency of the composites and same was studied by Guo et al [45] for wood fiber/carbon fiber reinforced polyethylene composite.…”

“…The loss in mechanical properties is exhibited due to the oxygenation and residue of impurities like peroxides and catalyst when exposed to prolonged high processing temperatures and shear. [3] Various natural fibers, [4][5][6][7] synthetic fibers, [8] and particulate reinforced composite have already been used by many researchers, academicians and, automobile, and aircraft industries. Various research investigations are being increasingly targeted in the direction of using natural and synthetic fibers, and other particulate reinforced composites to develop distinct automobile and aircraft parts.…”

“…[4,44,48] Resistance against agglomeration and compatibility of the FA with BM was exhibited due to the selective APTES/ CTAB treatment of FA. [4,5,44] These studies show that use of FA, apart from established application in construction and ceramic industries, can also be explored as a potential filler with the natural fiber assisted bio-composites. Hybridization with FA is not only limited to enhanced impact properties and reduced water absorption, but it opens an area of plethora of other engineering applications.…”

The investigation explores mechanical, thermal and thermomechanical behavior of hybrid composites post-recycling, and subsequent, 5 wt.% additional reinforcement to the recyclate of sisal (SSL) fiber fly ash (FA)/polypropylene (PP) hybrid composite. Impact of recycling and 5 wt.% of SSL fiber reinforcement of the recyclate on mechanical properties of hybrid composites made of 15-30 wt.% SSL and 5-15 wt.% FA were investigated. Noticeably, after recycling, a minimal loss of 2.39% only in tensile and 2.20% in flexural strength were recorded for the hybrid composites fabricated with 15 wt.% each of FA and SSL. The highest loss in tensile (10.32%) and flexural (4.22%) strength were reported for only 30 wt.% SSL fiber reinforced PP indicating that hybridization with FA has a benign effect on reducing property degradation. These lost properties were regained by reinforcing recycled composites with 5 wt.% of SSL fiber. Mechanical studies showed that the composite with 30 wt.% SSL fibers recycled and reinforced with additional 5 wt.% fibers showed a substantial improvement of ~10% and ~4% in the tensile and flexural strength while keeping the impact strength stable. FE-SEM images confirmed a reduction (~67%) in aspect ratio of the SSL fiber due to reprocessing. DMA demonstrated a decrease of ~11% in storage modulus of the composites after first recycling. TGA confirmed an insignificant change in the degradation temperature of the recycled and re-reinforced recycled composites versus fresh composites. The study paves the way for potential future recycling applications of waste natural fiber reinforced PP.

“…PLA/D/3 F G shows further decrease of mechanical characteristics which are probably due to the decrease in branching/crosslinking efficiency in the structure. In case of PLA/1 F G (1 wt%), ~22.27% increment in toughness is noticed with respect to PLA film 33 . It is also worth mentioning that the crazing plays a vital role in improving the toughness of the PLA bionanocomposite films, as seen in Figure 3(a 3 ).…”

Blending of poly (lactic acid) (PLA)/functionalized gum arabic (FG) in presence of dicumyl peroxide (DCP) presents a simple process to produce film using melt extrusion (recycle time ~ 4 min, screw speed ~60 rpm) at 180°C with tailored characteristics. The FTIR investigation shows that the confirmation of grafting of PLA chains on FG through formation of new C─C linkage. Properties of fabricated films such as morphological, mechanical, UV barrier and contact angle are examined to develop film with improved interfacial interaction, increased toughness, UV–C blocking effect (~95%) and hydrophobicity (~14%). Polarized optical microscopy (POM) studies reveal that PLA/1FG with and without DCP has more crystal density as compared to PLA at 120°C. This melt extrusion permits straightforward, feasible bionanocomposite film and has great potential as a modification with DCP assists to overcome particular drawbacks of FG.

“…Natural bers showed hydrophilic nature which limited their use in higher load and marine applications, but still, ample research is occurring on to reduce moisture absorption behavior of the plant bers. The phenomena of moisture absorption was studied when sisal bers were reinforced into polypropylene (Maurya et al 2021). The moisture absorption was high for natural ber based composite as compared to the synthetic bers (Chandramohan et al 2019).…”

This paper discusses on fabrication, testing and evaluation of delamination factor of nettle fiber based composites for low duty applications. The randomly oriented nettle fibers were used to fabricate the biocomposite by conventional hand lap up technique. Epoxy and Nettle based composite plates were developed by varying fiber weight percentage from 5% to 25%. The flexural, tensile, impact, chemical resistance and water absorption rate of developed nettle fiber based biocomposite were examined for different fiber weight fractions in the randomly oriented patterns as a unique and innovative attempt. During the investigation, flexural strength and tensile strength were improved up to 20 wt% of fiber addition and then it was decreased. This resulted in a continuous rise in impact strength with an enhancement in fiber wt. %. The influence of fiber weight percentage on water absorption and chemical resistance of fabricated composite was examined in different environments. The result showed that the nettle fibers can be used as an essential reinforcing material to design and fabricate mechanical and structural members for low duty application. The chemical behavior of nettle based composite was studied by the FTIR spectroscopy method and the presence of chemical functional group was confirmed. The drilling behavior of developed nettle/SiC/epoxy hybrid composites was evaluated by consider cutting process parameters like feed rate (0.125, 0.212 and 0.3 mm/rev), spindle speed (400, 600, 800 rev/min) and drill diameter (4, 6, 8 mm). Analysis of variance was used in designing experiments for the current investigation. Feed rate was found to be a very impressive factor in influencing the delamination factor.
