“…This supports the partial removal amorphous contents during pectinase treatment of PAACTPF. The extending vibrations of CH bond indicating the existence of cellulose and hemicellulose in the ACTPF and PAACTPF is represented by the trough seen at 2899 cm −1 45 . The presence of α–cellulose is designated by the extending vibrations of OH bond which is attributed to the trough seen at 3369 cm −1 .…”

This paper investigates thermo-mechanical, chemical, and morphological characteristics of alkali pretreated and enzyme treated Areca catechu tree peduncle fibers (ACTPFs) for probable reinforcement in polymer composites. ACTPFs were pre-treated with 0.4 M NaOH solution and treated with enzymes such as xylanase, laccase, and pectinase before investigations. Alkali pre-treated ACTPF (AACTPF) cum pectinase treated AACTPF (PAACTPF) exhibited maximum cellulose content 57.28 wt% and single fiber tensile strength 203.5 ± 22.12 MPa. Further, the crystallinity index and crystal size of PAACTPF was determined as 55% and 12.9 nm by x-ray diffraction analysis. Also, the prevalence of chemical bonds and thermal stability up to 233 C in PAACTPF was exposed through Fourier transform infrared spectroscopy analysis and thermogravimetric analysis respectively. Moreover, the coarse surface of PAACTPF viewed through scanning electron microscope owing to removal of amorphous contents makes it a considerable counterpart for substitutional reinforcement to artificial fibers in polymer composites.

“…It reveals that the presence of cellulose content of 60.31% formed a good fibre-matrix adhesion and surface roughness which makes that composite with better tensile strength of 204:32 ± 14:25 MPa. However, for the study by Okafor et al [56], the tensile strength and tensile modulus of Dioscorea alata stem fibres treated with NaOH and CH 3 COOH were found to be 151 MPa and 5.7 GPa, which is greater than Piliostigma racemose [57], Agave americana L. [58], Juncus effusus L. [59], and Kigelia africana [60]. This is mainly due to the maintaining gauge length (40 and 60 mm) and chemical treatment temperature (40 °C and 60 °C).…”

Various environmental concerns motivate scientists and researchers to look out for unique new materials in science and technology. In order to address the demand for polymeric materials with partial biodegradability, the usage of lignocellulosic fibre in the polymer matrix has risen. Lignocellulosic fibres are a cheap, easily renewable resource that is readily available in all regions. Cellulosic plant fibres also have a plethora of possibilities for use in polymer reinforcement because of their properties. Many researchers put their effort into developing a natural polymer with better mechanical properties and thermal stability using nanotechnology and the use of natural polymers to make its composites with lignocellulosic fibres. This study provides a review of the biodegradable composite market, processing methods, matrix-reinforcement phases, morphology, and characteristic improvements. In addition, it provides a concise summary of the findings of significant research on natural fibre polymer composites (NFRCs) that have been published. Indeed, a noticeably brief discussion is provided on the significant issues faced during composite extraction as well as the challenges encountered during the machining. Recent developments in the study of lignocellulosic fibre composites or NFRCs have demonstrated their enormous potential as structural elements in vehicles, aerospace structures, buildings, ballistics, soundproofing, and other structures.

“…The composite constitutive parameters, such as fiber aspect ratio, stack sequence, and constituent properties, influence sound absorption and vibration damping qualities. [145,[147][148][149][150][151][152] K. Senthilkumar et al [153] investigated the dynamic behavior of banana/sisal hybrid composites reinforced with epoxy, looking at the influence of banana fiber and the study of various fraction constituents, vibration properties such as natural frequency, and mode shapes of sisal/banana fibers reinforced with epoxy resin (L-12), indicating ductile behavior.

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.
