Chemical characterization of BA fibers showed the presence of various chemical contents such as cellulose of 74.89 wt. %, hemicellulose of 14.50 wt. %, wax of 0.31 wt. %, lignin of 12.8 wt. %, moisture of 11.71 wt. %, and ash of 19.29 wt. %. The density of BA fibers (BAFs) was showed 1285\u00a0kg\/m3<\/sup>. XRD analysis of BAFs showed a crystallinity index (CI) of 57.20% and size of crystallite of 1.68\u00a0nm. Tensile strength and strain to failure of BAFs examined through tensile test were 513\u20131226\u00a0MPa and 0.8\u20131.37% respectively. TGA portrayed the thermal steadiness of BAFs as 339\u00a0\u00b0C with 55.295\u00a0kJ\/mol kinetic activation energy, its residual mass was 23.35% at 548\u00a0\u00b0C. BAFs with high CI, less wax content, and better tensile strength make more suitable for making polymer matrix composites. SEM images of the BAFs surface depicted that the fiber outer surface has more rough which shows that they can contribute to hige fiber-matrix adhesion during composites preparation.<\/p>\n\n\n\n

Introduction<\/h3>\n\n\n\n

Due to the increase in adverse chemical reactions in the environment, research activities focus to swap synthetic fibers and its composites with natural or bio-based fibers and its composite. Synthetic fibers such as carbon, glass. nylon and kevlar have been widely used for making polymer composites for more than three decades. Increasing the demand of natural biodegradable fiber in the industries and the global market, it should need to find new natural fiber1<\/a>,2<\/a><\/sup>. Main purpose of this study investigates the mechanical, chemical, thermal and properties of novel natural fibers pull out from the skin of BA trees. Albizia is a tree of fabaceae family. It grows prominently in South and East Africa, Sudan and Ethiopia. It is also found in India and other countries like Sri Lanka, Bangladesh, etc. Performing the required analysis on integrated properties ensures the suitability of various natural fibers and it is very significant to have basic information for making composites. Therefore, studying the characteristics of such fibers through research plays an important role in introducing new natural fibers to the engineering and technology field. A standardized testing process for performing structural analysis of natural fibers was followed by many researchers3<\/a><\/sup>. The advantage of natural fibers is high compared with synthetic fibers like carbon, glass and kevlar, including lower production costs, reduced environmental impact, lighter weight, greater accessibility, and resistance to corrosion4<\/a><\/sup>.<\/p>\n\n\n\n

Many engineering industries, including construction, automotive, aerospace, electrical, marine, and home utilities the natural fiber reinforced polymer composites in a broader extent5<\/a>,6<\/a><\/sup>. Natural fibers\u2019 mechanical qualities were determined solely by their chemical make-up, growth region, source, age, and extraction technique7<\/a>,8<\/a><\/sup>. Many researches that the microfibrils are oriented spirally in the fiber axis, it exhibits rigid behaviour. The efficiency of reinforcing the natural fibers increase with increase in the length-to-diameter ratio (i.e. aspect ratio) of natural fiber over the critical ratio at which applied load or stress transfer between matrix and natural fiber occurs completely before the failure of composite samples. However, higher aspect ratio leads more fiber entanglement during the composite manufacturing processing and occurred poor dispersion9<\/a><\/sup>. In this way, many researchers have extracted new biofibers such as Pandanus Tectorius8<\/a><\/sup>, Acacia leucophloea10<\/a><\/sup>, Sansevieria Ehrenberg11<\/a><\/sup>, Prosopis juliflora12<\/a><\/sup> and Agave gigantea<\/em>13<\/a><\/sup>, using qualitative procedure. FTIR spectroscopy, XRD, TGA10<\/a><\/sup> and Single fiber testing was adopted to characterize the fibers. These fibers are used to develop the fiber reinforced polymer matrix composites. In many cases, the natural plant fibers like cotton, sisal, hemp, and jute are also used as reinforcements to produce a hybrid composite1<\/a>,2<\/a><\/sup>.<\/p>\n\n\n\n

Plants that create such natural fibers, on the other hand grows exclusively in certain places based on natural circumstances. It is important to test new fiber with advisable properties that may guarantee the development of green composites. It is expected that the future requirements for unique natural fibers will expand as new products development and technologies. The requirement and demand of natural fiber are continuously increased in the world market. Compensating the demand of natural fiber in the work marked, the new plant fiber should be identified and characterized before being used in composite developments. A new plant fiber is identified from a plant of\u00a0Bitter Albizia tress.<\/em>\u00a0The current study investigates the physical, thermal, tensile, and chemical properties of unique BA bark fiber, which has not been reported in the literature. BA fibers extracted manually from plant stalks and are subjected to mechanical property testing like tensile behaviour. Alongside, TGA, DSC, XRD, and FTIR, and morphology of fiber surface using Scanning Electron Microscopy are investigated in the present study. The BA tree was collected from agricultural land as per the Tamilnadu agricultural institution guidelines, Tamilnadu, India.<\/p>\n\n\n\n
