This investigation focuses on studying the properties of treated and untreated Musa acuminate peduncle fiber (MAPF)‐reinforced epoxy composites. The effect of fiber weight fraction and alkali treatment on the mechanical, thermal, and morphological characteristics of MAPF‐reinforced epoxy composites was investigated for the first time. A considerable enhancement in the tensile, impact, and flexural characteristics was observed at 20 wt% fiber; beyond 20 wt%, the properties were found to decrease. The increase in cellulose (from 66.43 to 74.22 wt%) and decrease in lignin (from 16.85 to 7.91 wt%) and hemicellulose (from 13.72 to 8.58 wt%) in alkali‐treated fiber resulted in a more crystalline structure. This led to improved tensile (tensile strength 53.61 MPa and tensile modulus 0.561 GPa), flexural (flexural strength 64.33 MPa and flexural modulus 5.43 GPa), and impact (90.33 J/m) composite properties compared to the untreated fiber composite. After tensile testing, the composite's fractured cross‐sections were investigated using scanning electron microscopy, which revealed that the alkali‐treated MAPF‐reinforced composite had fewer voids and improved fiber bonding. Thermogravimetric analysis, Fourier transform infrared spectroscopy, and atomic force microscopy studies also revealed that alkali‐treated MAPFs area promising reinforcement for the epoxy polymer matrix.

“…Conrad method was appropriate to determine the percentage of wax, and ash content was calculated as per the procedure described by Indran et al in 2014 17 . The measure taken to appraise moisture content was the weight difference between undried and dried fibers determined before and after treated at 80°C for 360 min in an oven 23 . The statistical formula used to calculate moisture content is given as the relation Equation ().…”

Novel natural plant fibers with significant features are to be explored at the moment due to their renewability, degradability, wide range acceptability, economic feasibility, and ecological standards over existing synthetic ones. Since the identification of potential plant fibers are getting much attention of scientists/researchers for the development of promising fiber reinforced composites. In the light of this, the present study identified a novel plant fiber from the peduncle of Furcraea selloa K. Koch and studied its anatomical, morphological, physico-chemical, thermal, mechanical and surface properties in order to explore its utility as a composite reinforcement. Anatomical study was satisfactory for identifying the presence and position of the fiber in the plant material. Good crystallinity (49.27%), high cellulose content (71.13%) and relatively low density (1127 kg/m 3 ) were found as the feasible features after physicochemical analysis. Indeed, desirable thermal stability (370 C) and tensile property (649.21 ± 16.52 MPa) of Furcraea selloa K. Koch peduncle fiber (FSPF) revealed its ability for high temperature required processing and applications. The morphological studies ensure good surface roughness and reduced microfibrillar angle (7.83 ± 0.23 ), which are recommended features for good fibermatrix addition. These promising properties are sufficient to deliberate FSPF as a new potential composite reinforcement, with good specific properties and high environmental impact.

The promising characteristic features of some natural plant fibers identified has driven many scientists/researchers to seek more plant fibers with good mechanical, thermal, tensile and surface properties. Plant fibers with such characteristics along with their renewable, degradable, eco‐friendly, cost‐effective nature could make them a probable competitor against synthetic ones, in many aspects. Since identification of novel plant fibers with superior quality is necessary at the moment in order to reduce the harmful effects of synthetic materials. Since the current study recognized a novel natural plant fiber from Echinochloa frumentacea and analyzed its efficiency for composite fabrication through various characterization practices. It was found from the physico‐chemical investigation that the fiber encloses with good crystallinity index (35.87%), cellulose content (60.31%) and relatively low density (896 ± 32.14 kg/m3). In fact, EFLF's has admirable thermal stability (330°C) and tensile strength (204.32 ± 14.25 MPa) designated its suitability for temperature varying environments. Conversely, the proposed fiber ensures good fiber‐matrix adhesion in spite of good surface roughness and decreased microfibrillar angle (9.27 ± 0.31°), noted by surface analysis. Hence, the current study recommends further utilization of EFLF as a reinforcing material with high specific qualities and low environmental effect, for composite manufacturing.
