“…Vishwanath et al studied the dielectric behavior of epoxy laminates reinforced with untreated and chemically treated bamboo fibers. 89 The chemical treatment of bamboo fibers was performed in two different ways, salt solution treatment and a combination of salt and alkaline treatment. As a result of these treatments, the lignin and hemicellulose contents in the bamboo fibers became relaxed, allowing them to realign and recrystallize.…”

This review provides an in‐depth analysis of the electrical responses and relaxation behaviors of various polymeric materials including fiber‐reinforced polymer composites, polymer nanocomposites (PNC), and nanofiller‐reinforced polymeric films and coatings using dielectric spectroscopy (DS). The underlying theory of DS, corresponding instrumentation, various dielectric parameters, relevant equations, interpretations, and polarization mechanisms are thoroughly explored. The impact of synthetic and natural fibers and a diverse range of nanofillers on the dielectric responses and relaxation mechanisms of fiber‐reinforced composites, and PNC and films, respectively, are also examined. For each summarized article, we provide an overview of the composite or film preparation, followed by concise explanations of the dielectric behaviors under diverse conditions, including variations in temperature, frequency, moisture levels, fiber/filler ratios, and chemical treatment. In essence, this review contributes to a nuanced understanding of the intricate relationship between material structure, properties, and performance via DS data interpretation across a spectrum of scenarios.

“…Because of their availability and characteristics, the generally applied plant cellulose fibers are sisal, kenaf, flax, jute, and hemp. [1][2][3][4][5][6][7] Moreover, specific scientific investigations examined the usefulness of utilizing plant cellulose fibers such as Fetula, Althea, Buriti, Sansevieria, and Isora in recent years. [8][9][10][11][12][13][14] Among the plant cellulose fiber, sisal is one of the most broadly applied fibers in yarns, twines, carpets, mats, rugs, cords, ropes, handcrafted, and mattresses components.…”

In the present investigation, the chemically treated and untreated sisal/hemp fibers, fly ash or titanium carbide (TiC) nanofillers, and Kevlar fabrics reinforced bio epoxy (Sr 56) polymer matrix were manufactured using the wet layup method. Experimentation was performed to study the physical, mechanical and thermal properties. This investigation also includes determining the influence of accelerated weathering on the specimen surface for 5 months. The tensile fracture of the sample before and after the accelerated weathering from scanning electron microscope (SEM) pictures exhibited that the extensive failure principles in the laminates in terms of matrix cracking, fiber breakage, delamination, and fiber pull out. The thermal analysis examined the onset, endset temperature, transition loss, and carbon residue which were also reduced after the accelerated weathering. It exhibits that adding fly ash or TiC nanoparticles as an altered inhibitor against the weathering in the bio epoxy hybrid composite scheme can reduce the undesirable impacts from moisture and Ultra‐violet light exposure.Highlights Sisal/hemp fibers were chemically treated to reduce hydrophilicity. Contact angle of KSCHCTBE56 improved to 84.04°. SEM confirmed uniform dispersion of fillers and enhance mechanical strength. Mechanical and thermal characteristics reduced after accelerated weathering.

“…It is an acceptable replacement for plastics. [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24] Typically, for the interior components of composite fabrication, many sectors, particularly the automobile and aircraft sectors, create natural fibers of various kinds such as primarily hemp, flax, sisal, coir, sugarcane, and bioresin systems. Due to their propensity for moisture, natural fiber tends to lose their integrity due to dimensional changes.…”

Biocomposites with inherent advantages such as biodegradable, recyclable, readily available, lower cost, and lower carbon footprint conveniently replace synthetic plastics. Despite being environmentally friendly, biocomposites should be functionally stable and structural in a rigorous environment. Thus, a study of biopolymer composites with exposure to various aging conditions, especially of humidity environment, which is of necessary concern, is considered here in this review. The aging experiments are often conducted at an accelerated rate at a specific time in respective environments to reduce the experimental time called accelerated aging. The vibration behavior of the biocomposites was conducted to determine the damping behavior of the composites is described in detail.
