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.

“…The kinetic activation energy of the numerous fibers, specifically A. saman fiber (64.01 kJ/mol), arial root F. amplissima fiber (66.25 kJ/mol), C. nucifera peduncle fiber (70.23 kJ/mol), and P. bauhinia fiber (90.58 kJ/mol) were already discovered by the various researchers. [ 14,18,26 ] Generally, the kinetic activation energy of the wooden materials are expected between 60 and 170 kJ/mol. All the findings of the thermal analysis of VMF were conveyed that VMF is the appropriate fiber to manufacture the fiber reinforced plastics.…”

“…[ 24 ] Previous literature reported that some of the cellulosic fibers such P. bauhinia fibers (1460 kg/m 3 ), Trachelospermum jasminoides fibers (1398 kg/m 3 ), and A. saman fibers (1450 kg/m 3 ) also own higher density than VMF. [ 14,25,26 ] This lesser density of VMF increases the suitability to develop lower weight applications. The diameter, density and chemical fractions of VMF and other plant fibers are synopsized in Table 1.…”

This article is designed to examine the aptness of Ventilago maderaspatana fiber (VMF) as reinforcement in polymer composites. A significant quantity of cellulose fraction (56.12 ± 5.42 wt%) in the VMF was estimated via chemical analysis. The X-ray diffraction analysis identified the presence of cellulose type-I and peak cellulose type-IV in the VMF, and it quantified the crystallinity index (25.88%) and crystalline size (26.12 nm) of the VMF. Various chemical functional groups in the VMF were categorized with the help of Fouriertransform infrared spectroscopic analysis. The thermal degradation behavior of the VMF was investigated with the help of thermogravimetric analysis, and it determined the thermal stability (200 C) and kinetic activation energy (62.46 kJ/mol) of VMF. The scanning electron microscopic and energy dispersive X-ray spectroscopic analysis revealed the existence of contaminations, hemicellulose and lignin on the outer layer of VMF, and it was confirmed by atomic force microscopic analysis. The lower density (1236 ± 18.42 kg/m 3 ) and better tensile strength (383.7 ± 16.07 MPa) of the VMF enabled the possibility of use as reinforcement in fiber reinforced plastics.

“…Indeed, the availability of natural fibers varies according to the geographical location on the planet, which is of interest to the environment since each industrial center can locate available resources and thus meet the demand for green materials while using new, accessible and low-cost tropical species [19]. Thus, works have focused on the study of the properties of new plant fibers such as those derived from pineapple leaves [20], okra stems [21], Sida cordifolia [22], Arundo donax [23], Lygeum spartum [24], Coccinia grandis [25], Markhamia lutea [26], Erythrina variegate [27] and Albizia Saman [28]. Concerning plant fibers issued from tropical plants in Central, East and West African countries, some studies are related to the identification of properties of African star apple leaves [29], Bast fibers of Triumfetta cordifolia [30] and Rhectophyllum camerunense fibers [31][32][33].…”

Plant fibers are being increasingly explored for their use in engineering polymers and composites, and many works have described their properties, especially for flax and hemp fibers. Nevertheless, the availability of plant fibers varies according to the geographical location on the planet. This study presents the first work on the mechanical properties of a tropical fiber extracted from the bast of Cola lepidota (CL) plant. After a debarking step, CL fibers were extracted manually by wet-retting. The tensile properties are first identified experimentally at the fibers scale, and the analysis of the results shows the great influence of the cross-section parameters (diameter, intrinsic porosities) on these properties. Tensile properties of CL fibers are also predicted by the impregnated fiber bundle test (IFBT). At this scale of bundles, a hackling step, which reduces shives and contributes to the parallelization of the fibers within bundles, improves tensile properties predicted by IFBT. The comparison with the properties of plant fibers given in the literature shows that CL fibers have tensile properties in the same range as kenaf, flax or hemp fibers.
