The main objective of this work was to estimate the usefulness of response surface methodology (RSM) and genetic algorithm (GA) in modeling and predicting the strength of jute/poly(lactic acid) (PLA) composite laminates. Firstly, the impact of the hot water treatment on the thermal, molecular structure, and morphological characterizations as well as kinetic analysis of jute fibers were performed by Thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy (FTIR), Scanning electron microscopy (SEM). The FTIR results showed that the hot water treatments reduced the content of lignin, hemicellulose, and impurities of the fibers. Hot water treated fibers exhibited higher thermal stabilities compared with untreated fibers as shown with TGA results. The SEM results showed effect contact surface area improved after the hot water treatment, leading to better mechanical properties of bio‐composites. Secondly, the influences of the ply orientation, plies and fiber content on the tensile strength and flexural strength of the hot water treated fibers composites were evaluated by RSM. RSM with the Box Behnken Design was utilized to establish the quadratic models of two objectives in response to input parameters. Analysis of variance (ANOVA) was used to determine percentage contribution of various parameters on two quality objectives. According to the ANOVA results, ply orientation had the most important impact on tensile strength while the ply orientation‐fiber content interaction had the most important impact on flexural strength. Finally, multi‐objective optimization was carried out to maximize tensile strength and flexural strength using the desirability function and GA. The optimized results both showed an acceptable relative error between experimental and optimized values.

The present study concentrates on the mechanical, morphological, water absorption and burning behavior of hemp/E-glass fiber reinforced hybrid composites (FRHC). The surface adhesive characteristics of the acquired bi-directional hemp fiber mats were enhanced by treating them with an alkali solution. Furthermore, the present work extends to identify the effects of two 2-dimensional graphene and MXene nanoparticles as filler on the hardness, flexural and tensile behavior as well as water absorption and flammability characteristics of the FRHC. The glass fiber (G), hemp fiber (H), and hemp/glass (G/H) fiber reinforced epoxy LY556 laminates were fabricated by using the hand lay-up method followed by the vacuum bagging approach. A 30% and 12% increase in the flexural and tensile strength of the H/G hybrid composite has been observed by adding 1% of graphene as an additional reinforcement compared with the neat FRHC. However, the use of MXene as additional reinforcements shows 45% and 10% enhancement in the flexural and tensile strength of the H/G hybrid composite. In addition, the water absorption capacity of MXene-filled G/H hybrid composites is found to be almost half of that filled with graphene. Similarly, the flammability results reveal that the burning rate of graphene-reinforced H/G hybrid composite is 17.44 mm/min. When comparing the mechanical, water absorption, and flammability characteristics of graphene and MXene-reinforced G/H hybrid composites, graphene gives more intensifying results than MXene.The scanning electron microscopic studies are also incorporated to investigate the fractured surface topography of the FRHC.

Environmental pollution, such as air, water, and soil pollution, has become the most serious issue. Soil pollution is a major concern as it generally affects the lands and makes them non-fertile. The main cause of soil pollution is agro-waste. It may be possible to mitigate the agro-waste pollution by re-utilizing this agro-waste, namely natural fibres (NFs), by blending into polymer-based material to reinforce the polymer composite. However, there are pros and cons to this approach. Consequently, the polymer composite materials fabricated using NFs are inferior to those polymer composites that are reinforced by, e.g., carbon or glass fibres from the mechanical properties’ perspectives. The limitations of utilizing natural fibres in polymer matrix are their high moisture absorption, resulting in high swelling rate and degradation, inferior resistance to fire and chemical, and inferior mechanical properties. In particular, the NF polymer composites exhibit inferior interfacial adhesion between the fibre and the matrix, which, if improved, ultimately overcome all the listed limitations and improve the mechanical properties of the developed composites. To improve the interfacial adhesion leading to the enhancement of the mechanical properties, optimum chemical treatment such as Alkalization/Mercerization of the fibres have been explored. This article discusses the Mercerization/Alkali surface treatment method for NFs and its effects on the fibres regarding the Mercerization/Alkali surface treatment method for NFs and its effect on the fibres regarding their utilization in the polymer composites, the morphological features, and mechanical properties of composites.
