Humans are the only species who generate waste materials that cannot be broken down by natural processes. The ideal solution to this waste problem would be to employ only compostable materials. Biodegradable materials play a key role in creating a safer and greener world. Biodegradability is the gift that keeps on giving, in the sense of creating an Earth worth living. The future is thus best served by green energy, sustainability, and renewable resources. To realize such goals, waste should be considered as a valuable resource. In this context, Zea mays (Zm) root fibres, which are normally considered as agricultural waste, can be used as reinforcing substances in polymer matrices to produce structural composite materials. Before being used in composites, such fibres must be analysed for their physical properties. Chemical treatments can be employed to improve the structural quality of fibres, and the changes due to such modification can be analysed. Therefore, the current work examines the effect of permanganate treatment on the surface properties of Zm fibres. The raw and potassium permanganate-treated samples were assayed for various properties. Physical analysis of the fibre samples yielded details concerning the physical aspects of the fibres. The thermal conductivity and moisture absorption behaviour of the samples were analysed. Chemical analysis was employed to characterize the composition of both treated and untreated samples. p-XRD was employed to examine the crystalline nature of the Zm fibres. Numerous functional groups present in each sample were analysed by FTIR. Thermogravimetric analysis was used to determine the thermal stability of Zm fibres. Elemental analysis (CHNS and EDS) was used to determine the elemental concentrations of both raw and treated samples. The surface alterations of Zm fibres brought on by treatment were described using SEM analysis. The characteristics of Zm roots and the changes in quality due to treatment were reviewed, and there were noticeable effects due to the treatment. Both samples would have applications in various fields, and each could be used as a potential reinforcing material in the production of efficient bio-composites.

Nowadays, industries place a strong emphasis on low-cost, biodegradable materials with long lifespans. As a result, businesses are concentrating on creating composite materials utilizing the world’s plentiful supply of natural fibers. In this study, acacia and raffia fibers are combined with epoxy resin and a hand layup method to create a biodegradable composite laminate. This article investigates the effect of fiber orientation on the mechanical and morphological evaluation of composite materials that have been manufactured. Three different kinds of composites were fabricated in this work: Composite 1, which contained acacia fiber; Composite 2, which was built of acacia and raffia fiber; and Composite 3, which was made of raffia fiber. While Composite 2 is a hybrid composite in this instance, Composites 1 and 3 are monofiber composites. In accordance with the ASTM standards, testing was performed to investigate the different mechanical behaviors, including tensile, flexural, double shear, delamination, hardness, and impact. The results demonstrate that Composite 1 has strong tensile strength, flexural strength, double shear, and hardness tests with a 45° fiber orientation. The 90° fiber orientation of Composite 1 performs well in the inter delamination test. The result demonstrates that composite 1 of type 0 absorbs greater energy. Additionally, Scanning electron microscopy was used to conduct morphological examinations in order to investigate the internal structural failure of the composites. It was found that the composite laminate has fiber cracks, pullouts, and voids, which were reduced with the right curing times and stress.

The comprehensive characteristics of an ecologically viable cellulosic fiber from the leaf sheath of Licuala grandis L tree are alkaline modified and investigated in this study. The percentage of cellulose in ideally alkali‐modified Licuala grandis leaf sheath fiber (IALGLSF) increased by 15.8% following a 1 h treatment with a 5% (w/v) alkali buffer. Comparing IALGLSF to raw Licuala grandis leaf sheath fiber (LGLSF), an individual strand tensile testing revealed a 13.2% rise in tensile characteristics. Crystallinity index (CI) analysis using x‐ray diffraction (XRD) showed that IALGLSF had a 12.5% greater CI over LGLSF. Also, Fourier transform infrared spectroscopy (FTIR) experiments validated partial removal of noncrystalline constituents from IALGLSF as a consequence of alkali alteration. Additionally, thermogravimetric (TGA‐DTG) study, which is supported by differential scanning calorimetry (DSC) inquiry, demonstrated that alkali alteration‐enhanced IALGLSF's thermal resistance from 223 to 229°C. Similarly, scanning electron microscopy (SEM) has shown that rougher surface appearance of IALGLSF results from selective removal of noncrystalline constituents, which also provides better matrix contact during reinforcement for the production of eco‐friendly composites. The indicated outcomes validated that IALGLSF serves as a beneficial substitute for potentially harmful synthetic fibers in the production of sustainable biocomposites.
