The present investigation aimed to understand the physicochemical properties of the new cellulosic fiber extracted from the bark of Silybum marianum (SM), in view of using it as a potential reinforcement for polymer composites. The morphological and anatomy, physical, thermal and mechanical properties of fibers were firstly discussed in this paper. The Silybum marianum fibers (SMF) were characterized by scanning electron microscopy, Fourier transform infrared, thermogravimetric analysis (TGA), optical microscope, X-ray diffraction (XRD), and single fiber tensile test. The average Young’s modulus and the breaking stress data presented by the fibers are 15.97 GPa and 201.16 MPa, respectively. XRD reveals the presence of cellulose with a crystallinity index of 45%. Thermal stability (250°C) and maximum degradation temperature (357.72°C) of the SMF are established by the thermogravimetric analysis. An analysis of the mechanical properties was carried out on a population of 35 samples using Weibull statistics with two and three parameters.

“…The first three consecutive peaks in the spectrogram are associated with the cellulose component in the MAF and their corresponding chemical functional groups are OH stretching (3277 cm −1 ), CH and CH 2 stretching (2921 cm −1 ) and C–H stretching of alkanes (2850 cm −1 ). [ 28,47,49 ] A tiny peak at 2357 cm −1 confirms the presence of wax components and contaminations (CC stretching) in the MAF. [ 50 ] The subsequent peak at 1730 cm −1 shows carbonylic group CO stretching of lignin in the MAF.…”

This research investigated the scope of using a fiber harvested from Mucuna atropurpurea (MAF) plant as reinforcement in fiber-reinforced plastics. An optical microscope and a pycnometer were used to calculate the diameter (289 ± 21 μm) and density (1082 ± 29 kg/m 3 ) of the MAF. Using chemical compositional analysis, 58.74 ± 5.74 wt% cellulose and 16.31 ± 3.21 wt% hemicellulose, and 14.22 ± 3.36 wt% lignin and 0.38 ± 0.08 wt% wax components were found in the MAF. Numerous chemical stretching in the MAF were checked using Fourier transform infrared spectroscopy. Briodo analysis (68.08 kJ/mol) showed the kinetic activation energy of the MAF. Surface morphological inspections suggested surface treatments of MAF due to contaminations and wax on the fiber surface. The statistical analysis conducted for determining the tensile properties of MAF revealed that MAF is a suitable candidate to produce fiber-reinforced plastics. Characterization of MAF-reinforced polyester composites showed that 40 mm fiber length and 30 wt% fiber enhanced tensile strength (109.51 ± 2.1 MPa), flexural strength (156.62 ± 3.1 MPa), and hardness (94 ± 4 HRRW). Fractography images of composites with fiber pull-outs in the MAF-reinforced plastics were taken for analysis. Less cavities and voids in the 30 wt% MAF-reinforced composites were found along with reduced water absorption.

“…Hence, roughness of FBRF is greater than that of Symphorema involucratum (6.64 nm) and Acacia concinna (11.21 nm). [15,23,26] The porous nature of the fiber was further confirmed by the negative surface skewness (R sk ) value of À0.321 (crosswise) and À 1.134 (longitudinal). Likewise, surface kurtosis (R ku ) values of 3.608 and 4.167 show that the fiber has a coarser surface, which would provide good interfacial adhesion while reinforcing.…”

The demand of plant fibers is increasing day by day due to the worldwide acceptance of natural plant fibers for various applications in a variety of sectors. However, the identification of suitable plant fibers with superior properties is the need of the hour in the context of developing more eco-friendly, renewable, cost-effective, and fiber-based materials. This study was designed with the intention of identifying suitability of Ficus benjamina L. aerial root fiber (FBRF) as a potential reinforcement for composite structures. The fundamental physicochemical, mechanical, thermal, and morphological features were investigated to explore the potentiality of FBRF. This study was advantageous in finding the occurrence of fiber in aerial root, fiber position, and characteristics of fibrous cells. The density analysis proved that the fiber possessed a relatively low density (1175 ± 22.14 kg/m 3 ), which shows its lightweight applicability. High cellulose content (64.48%) and crystallinity index (55.17%) observed for tested fibers in turn enhanced the thermal and mechanical behavior of the fiber. The tensile strength of 292.66 ± 12.32 MPa and thermal stability of 330 C were worthy for considering it for high-temperature processing and applications. The investigation of surface properties revealed that FBRF partake good surface roughness, which offers good fiber-matrix interfacial bonding. Hence, this study endorses further use of FBRF as a good reinforcement for composite manufacturing.
