“…These fibers were thoroughly washed with distilled water to remove the excess acid present in the fibers. Final washing was done with Sathishkumar water containing 1% acetic acid, and these fibers were dried in normal atmospheric temperature for 8 h and in a hot air oven at 70 C for 3 h. 28,29 Those fibers are used to prepare the NaOH treated SEFs-reinforced polyester composite (Na).…”

The static, dynamic (like storage modulus and damping behaviour (tand)), thermal, hardness and machinability properties of Sansevieria ehrenbergii fiber-reinforced polyester composites were compared with traditionally available materials like plywood, hardboard sheet, paper board and twisted paper according to ASTM standards. The stress-strain curves of the polyester composites and traditionally available materials were analysed, and the results show that the best tensile, flexural and impact properties were achieved with KMnO 4 -treated S. ehrenbergii fiber-reinforced polyester composites. The storage modulus of hardboard sheet and KMnO 4 -treated S. ehrenbergii fiber-reinforced polyester composite was the highest in the glassy and rubbery regions. The tand peak height was minimum and peak width was maximum for hardboard sheet and KMnO 4 -treated S. ehrenbergii fiber-reinforced polyester composites. The thermal stability and hardness of the hardboard sheet were the highest compared to S. ehrenbergii fiber-reinforced polymer composites. The delamination factor and water absorption of KMnO 4 -treated S. ehrenbergii fiber-reinforced composites and hardboard sheet were lowest compared with the other materials.

“…[15][16][17] Catalyst namely cobalt naphthalene and accelerator methyl ethyl ketone peroxide (MEKP) were used to cure the resin. 15,16,17 Thermoset isophthallic polyester resin was one of the economical resins when compared to other resins owing to its very low waterabsorbing capability, excellent bonding tendency as well as mechanical properties. The distinctive properties of the isophthallic polyester resin were tested and listed in Table 2.…”

The natural fiber-reinforced composites have been widely used in many applications and emerging as a replacement for wood materials. The wood is a main component for making chairs, tables, and various furniture elements. The snake grass fiber-reinforced polymer composites chair is fabricated and is used to replace the usage of wood chair for commercial application. The mechanical properties such as flexural and compressive and the water absorption at various time periods have been analyzed. These properties are compared with SAL wood and the inferences are discussed. The preparation and material cost of the composites are compared with SAL wood chair. The composite chair have higher mechanical properties and lower cost for fabrication compared to SAL wood chair. The total weight of composites chair is lower than wood. Hence, snake grass fiber-reinforced polymer composites might replace SAL wood and other wood chairs and save trees, which in turn helps in reducing global warming.

In this research work, the untreated and various concentrations of alkali treated continuous mulberry fibers were used as reinforcement in polyester matrix and its static and dynamic mechanical properties were investigated. The composites were fabricated using untreated, 5%, 10%, and 15% alkali treated mulberry fibers (ATMF) reinforced in polyester resin by compression molding technique. The result showed that the 10% alkali treated mulberry fiber composite (ATMFC) considerable increase in tensile, flexural, and impact properties compared to untreated, 5% and 15% alkali treated mulberry fiber composites. The 15% alkali treated mulberry fiber composite showed decrease in water absorption property. The fractured surface morphology of composite samples was examined by Scanning Electron Microscopy (SEM). The Dynamic Mechanical Analysis (DMA) shows that the 10% alkali treated mulberry fiber composite enhanced storage and loss modulus compared to untreated, 5% and 15% alkali treated mulberry fiber composites. The weight loss of untreated, 5%, 10%, and 15% alkali treated composites were studied under varying temperature by Thermo Gravimetric Analysis (TGA) and Differential Thermo Gravimetric analysis (DTG).
