“…The band at 1735 cm −1 was associated with the absorption of C=O stretching of ester and carboxyl groups in hemicelluloses in mechanically extracted BPSFs. However, the band disappeared in the spectra for chemically and enzyme-extracted BPSFs, because of the removal of hemicelluloses (Sreenivasan et al 2011b;Reddy et al 2013;Buana et al 2013). The FTIR spectra confirmed that chemical and enzymatic treatments could effectively reduce the hemicellulose and lignin contents.…”

“…The fiber bundles provide stiffness for the BPS sheath and are found in the periphery of the stem. The fiber bundles are of great importance commercially because they almost never split during extraction (Sreenivasan et al 2011b). The bundle cap fibers were found at one end of the vascular tissues.…”

“…Natural fibers have many advantages, such as biodegradability, renewability, wide availability, low density, low cost, high tensile strength, and high stiffness, which are beneficial for developing lightweight, environmentally friendly structural composites (Reddy et al 2013). Therefore, great efforts have been made to use natural fibers to reinforce polymer composites for applications in the aircraft, automobile, electronics, and medical industries (Sreenivasan et al 2011b;Khan et al 2013).…”

Banana pseudo-stem fibers (BPSFs) have desirable tensile properties. In this study, BPSFs were extracted using mechanical, chemical, and enzymatic methods. The aim was to evaluate the effect of these three extraction methods on the tensile, thermal, and morphological properties of BPSFs. Microstructural analysis showed the presence of structural and arch fibers in banana pseudo-stem (BPS). The average tensile strength and elongation for mechanically, chemically, and enzymeextracted BPSFs were 210, 333, and 235 MPa, and 0.8%, 1.6%, and 1.4%, respectively. Young's modulus was enhanced by 19.1% in the mechanically extracted BPSFs compared with that of chemically extracted BPSFs. The morphology of BPSFs was correlated with their tensile properties via scanning electron microscopy (SEM) image analysis. Fourier transform infra-red (FTIR) and X-ray diffraction (XRD) analyses of fibers showed that chemically extracted BPSFs contained less hemicellulose and lignin with a crystallinity index of 61.2%. Chemically extracted BPSFs exhibited enhanced thermal properties over mechanically extracted BPSFs. Mechanically extracted BPSFs demonstrated similar thermal and tensile properties to chemically and enzyme-extracted BPSFs. Thus, mechanically extracted BPSFs could act as highly suitable reinforcing agents in bio-based composite material preparation. Given that mechanical methods need no chemicals and they are environmentally friendly, such techniques have potential applications.

The Poly Lactic Acid (PLA) is a completely biodegradable potential alternate of plastics applied in Civil infrastructural field because it posses very good "Ultimate Withstanding" properties. It can also be stated that hybrid fiber composite is having higher Mechanical and Physical characteristics compared with Mono fiber reinforced composite. Naturally existing Snake Grass (SG) and Elephant Grass (EG) reinforced PLA matrix fabrication is being narrated in this research article. By experimentation and analysis of results, it is proved that the Tensile strength, % Elongation, Flexural strength, Impact strength and Water absorption properties of SG & EG reinforced PLA composite is better than that of pure PLA Matrix.

“…A microstructural analysis of Sansevieria cylindrica leaves showed the presence of structural fibres and arch fibres. Polarised light microscopy and scanning electron microscopy of these fibres revealed a hierarchical cell structure that consisted of a primary wall, a secondary wall, a fibre lumen and middle lamellae [17]. Polyester filled with Sansevieria cylindrica fiber composites were studied successfully on mechanical properties, performance increases in increasing fiber content and optimized at 40wt.% fiber ratio were recorded [18].…”

This paper deals with the preparation and characterization of epoxy tamarind fruit (Tf) and Sansevieria cylindrica (Sc) hybrid composites containing fiber 0:20, 5:15, 10:10, 15:5 and 20:0 of (Tf:Sc) combinations loading. Sansevieria cylindrica leaves were used in this paper for extracting fiber out of it and in the similar manner ripen Tamarind fruit was used to extract fiber. Two different fibers viz. tamarind fruit/ Sansevieria cylindrica fibers were loaded into the epoxy system to develop the hybrid composites. The tensile and flexural properties of the resulting 20 wt. % loading of Tf/Sc/epoxy hybrid composites were examined. The resulting hybrid composites of 20 wt. % Tf/Sc with varying combinations exhibit the optimum improvement of mechanical properties and dielectric strength. 2 °C rise in decomposition temperature and 5 °C rise glass transition temperature were observed from the TGA and DSC thermal analysis. The fractured cross sections of flexural samples were assessed their performance as a function of fiber loading of Tf/Sc/epoxy hybrid composites by SEM analysis.
