Abstract
This research aims to characterize and analysis of newly cellulosic fiber extracted from Inula viscosa bark. The obtained Inula viscosa fibers were also characterized after having been treated with alkali and permanganate treatments. The effect of chemical treatments on the mechanical, physical, chemical and thermal properties of Inula viscosa fibers was investigated by using, X-ray diffraction, thermo gravimetric, scanning electron microscope analysis, optical microscope test, tensile and droplet tests. The treatment with permanganate was found to have the higher density (1.154 ± 0.032 g/cm3) compared to that of the untreated ones (1.040 ± 0.010 g/cm3). The best mechanical properties were also achieved when the permanganate treatment was adopted. In this pretext, tensile strength values and Young modulus were found as 196.99 ± 28.89 MPa and 12.98 ± 2.36 GPa, respectively. It is estimated that the fiber treatments will enable high-quality Inula Viscosa Fiber-reinforced polymer composites for use in the industry.
Highlights
Societal needs for new environmentally friendly materials make scientists to develop materials from nature itself
The untreated Inula viscosa (IV), 3% alkaline treated IVs, and 3 % permanganate treated IVs were evaluated for their physical, morphological, crystalline structure, thermal degradation, mechanical and micromechanical properties
The density of untreated raw IVF and alkali and permanganate treatment IVF is lower than that other natural fibers have
Summary
Societal needs for new environmentally friendly materials make scientists to develop materials from nature itself. Researchers and scientists are currently focusing on green composite materials from plants fibers with good fiber yields, cost-effective without compromising mechanical properties [5,6,7]. This is justified because, on the one hand, natural fibers have the status of renewable and durable materials; on the other hand, they are abundant, light, of moderate resistance, high specific modulus compared to synthetic ones [8,9,10]. Composite materials reinforced by natural fibers have contributed significantly to the human race's well-being and technological development. The construction industry, vehicle parts, domestic applications, aerospace, sports equipment, and others have been more inclined to use cellulosic fibers because of their benefits [11, 12]
