What is it about?
The present investigation aimed to understand the physicochemical properties of new natural fiber extracted from Albizia amara (AA) bark. The chemical composition and structural, thermal, and tensile properties of AA fibers (AAFs) were investigated. The results indicated that AAF had crystallinity index of 63.78%, cellulose of 64.54 wt%, hemicellulose of 14.32 wt%, lignin of 15.61 wt%, and low density of 1043 kg/m3. Thermogravimetric analysis shows that AAFs were thermally stable up to 330.6°C and the functional groups of the AAFs were identified by Fourier transform infrared analysis. The AAFs exhibited tensile strength of 640 ± 13.4 MPa with strain rate of 1.57 ± 0.04%. This investigation reveals that AAFs could be a suitable material as reinforce agent in natural fiber–polymer composites for different applications.

Why is it important?
Potential source for natural fibers. Plant grows in arid conditions is an advantage..
Perspectives
Natural fibers and agro-industrial residues are important source in the preparation of composites. They can help to reduce the environmental impact due to the indiscriminate use of synthetic polymers. Related publications: (i) G. T. Mahesha, B. S Shenoy B, M. Vijaya Kini, K.
