“…Cellulose is one of the strongest components present in the fiber that provides mechanical strength to the fiber. [ 3 ] The lignin content of BV fiber was found to be 10 to 13 wt%, which is higher than that of flax, hemp, sisal, and cotton. Lignin provides strength and stiffness to the fiber.…”

“…Then, the density of BV fiber has calculated by the Equation ) given below:

ρ = \frac{m_{2} - m_{1}}{((), m_{4} - m_{1}) - ((), m_{3} - m_{2})} \times ρ_{k}

where ρ is the density of BV fiber (g/cm 3 ), ρ k is the density of kerosene (0.816 g/ cm 3 ), m 1 is the mass of the empty pycnometer (kg), m 2 is the mass of the pycnometer filled with chopped BV fibers (kg), m 3 is the mass of the pycnometer filled with chopped BV fibers and kerosene (kg) and m 4 is mass of the pycnometer filled with kerosene (kg).

The present work aims to analyze the influence of chemical treatment on thermal, morphological, mechanical, and water absorption characteristics of a new natural Bauhinia Vahlii (BV) stem fiber. In this research study, the BV fiber surface was modified through different chemical treatments such as alkalization, bleaching, and benzoylation. The effect of these chemical treatments on the fiber are visualized through the scanning electron microscope (SEM) micrographs. SEM ensures the presence of voids and rough surfaces with the removal of deleterious substances from the fiber. The results obtained from Fourier transform infrared ensure the presence of cellulose, hemicellulose, and lignin compounds in the case of untreated and treated BV fiber. Also, X‐ray diffraction analysis gives a higher crystallinity index for treated BV fiber. Thermogravimetric analysis confirms there is an increase in the thermal stability of the fiber after chemical treatment. The increase in tensile strength and young's modulus confirms improvement in the mechanical properties of the BV fiber after chemical treatment. The water absorptivity test ensures there is a reduction in the hydrophilic nature of the BV fiber after chemical treatment, which promotes better adhesion between fiber and matrix.

“…The deconvolution of the X-ray diffraction profiles showed the presence of three peaks and an amorphous bump. For both VBs and FSs the highest intensity peak was observed at 2θ = 22.2°, average intensity peak at 2θ = 15.86° and a peak of low intensity at 2θ = 35°, which were assigned to the (002), (101 " ), and (040) crystallographic planes (Jebadurai et al, 2018).…”

Date palm rachis fibers are rich in cellulose, relatively inexpensive, and readily available in Algeria. The aim of this study is to investigate the morphology, structure, mechanical and physicochemical characteristics of both vascular bundles and fiber strands extracted from date palm rachis. The difficulties encountered are associated to the extraction of the fibers without damaging them. The study focuses on the morphological and surface roughness analysis using optical and scanning electron microscopies (SEM), and a non-contact 3D profiler. The chemical, physical and thermal properties have been studied using Fouriertransform infrared (FTIR) spectroscopy, energy dispersive X-ray spectroscopy (EDX), X-ray diffraction (XRD), thermogravimetric analysis (TGA), and differential scanning calorimetry (DSC). The mechanical properties were accessed by tensile tests and they were analyzed using two-parameter Weibull distribution.
