Extraction and characterization of natural cellulosic fiber from fragrant screw pine prop roots as potential reinforcement for polymer composites

Abstract

Biodegradable natural plant fiber isolated from the prop roots of fragrant screwpine (FSP) plant has been thoroughly studied as a potential replacement for artificial fiber in light weight bio-based composite applications. Chemical, physical, Fourier transform infrared spectroscopy, X-ray diffraction, scanning electron microscopy, differential scanning calorimetry, and thermo gravimetric studies were used to determine the appropriateness of FSP fiber for use as a novel reinforcement. FSP fibers were determined to have a density of 1.3852 g/cm 3 and a diameter of 27-280 μm respectively. Good specific strength and bonding qualities are provided by a high cellulose content (73.10 wt%) and a low wax content (0.35 wt%). The tensile strength of raw FSP fiber was 915 ± 195 MPa, the young's modulus was 33 ± 12 GPa, and the average strain to failure rate was 4.59 ± 2.17%. Thermal analysis (TG and DTG) confirmed FSP fiber's thermal stability up to 235 C. The findings revealed that FSP fiber (FSPF) is an excellent alternative for constructing polymer-based bio-composites and other high-value products with both technical and environmental requirements.

A spatial distribution effect of almond shell bio filler on physical, mechanical, thermal deflection and water absorption properties of vinyl ester polymer composite

“…Beyond 25 wt% of AS particle loading, there is a reduction in the flexural strength of the prepared composite. This may be due to higher particle loading, leading to weak interfacial bonding of AS particles with the vinyl ester matrix 35 …”

“…This may be due to higher particle loading, leading to weak interfacial bonding of AS particles with the vinyl ester matrix. 35 Figure 6 shows the flexural modulus of the AS particle-filled vinyl ester polymer composites. Any increase in the AS particle loading increases the flexural modulus of the composite.…”

Extraction and Characterization of New Cellulosic Fiber from Catalpa bignonioides Fruits for Potential Use in Sustainable Products

“…Micropores and the high roughness of the fiber surface increase the interfacial adhesion between the fiber and matrix when used in composites. This also causes an increase in the surface area, thus improving the spinning and dyeing properties of the fiber [ 26 , 37 , 39 ]. Figure 2 c,d illustrate the cross-section SEM micrographs of the Catalpa bignonioides fibers.…”
