“…Therefore, improved interfacial interaction leads to good bonding and less matrix fracture in KMnO 4 treated SGFC. The present impact results are similar to Sreenivasan et al 1 They investigated the Charpy impact strength of various treated and untreated S. cylindrica/polyester composites. It reveals that the impact strength of KMnO 4 treated S. cylindrica/polyester composites is higher than that of untreated and other treated fiber composites.…”

Snake grass fibers are subjected to various chemical surface modifications such as alkali, benzoyl peroxide, benzoyl chloride, potassium permanganate and stearic acid. These fibers are utilized to fabricate the longitudinal oriented fiberreinforced composites at 40% weight fraction of fiber. The mechanical properties of treated fiber composites are found to be higher than those of raw ones. Potassium permanganate treated fiber composites has optimum mechanical properties than other chemicals treated snake grass fibers composites. The scanning electron microscopic images of the tensile and impact fractured composites containing treated and untreated fibers have been examined. The fiber pullout from the specimen has been found low for the treated fibers compared to untreated fiber composites. The kinetics of water absorption of the composites studied at various time intervals and temperature reveals that the treated fiberreinforced composites has less water uptake compared to untreated one.

“…[13] Some studies reported that polymer composites fabricated with reinforcement by chemically treated alfa, coir, bagasse, and sansevieria cylindrical fibers had improved mechanical properties compared to untreated composites. [14][15][16] In an interesting study, other researchers fabricated jute=bagasse hybrid composites with modified bagasse fiber, and the results indicated that fiber surface modification improved fiber=matrix interaction and significantly increased mechanical properties of hybrid composites. [17] Sodium lauryl sulfate (SLS) treatment has shown improvement in tensile, flexural, and impact strength of both nonwoven and woven hybrid composites compared to alkali-treated composites.…”

Treatment of oil palm empty fruit bunch (EFB) and jute fibers is carried out by using 2-hydroxy ethyl acrylate (2-HEA) to increase the interfacial bonding of fibers with the epoxy matrix. Fourier transform-infrared (FT-IR) spectroscopy and scanning electron microscopy (SEM) were used to measure the change of surface composition of the fibers after treatment. Modified oil palm and jute fibers were used as reinforcements for epoxy matrix to fabricate hybrid composites by the hand lay-up technique. Tensile and morphological properties of hybrid composites were studied, and tensile properties of hybrid composites prepared from chemically treated oil palm=jute fibers were found to be better than those of untreated hybrid composites. SEM micrographs disclose that interfacial bonding between fiber and matrix significantly improved in the hybrid composites. Developed hybrid composites can be exploited as alternative materials for development of automotive and structural components instead of synthetic fiber-reinforced polymer composites.

“…The various chemical concentrations have been reported for fiber surface treatments. Sreenivasan et al 11 analysed the Sansevieria cylindrica fiber treated with alkali which was a primary treatment of other chemical treatments such as benzoyl peroxide, potassium permanganate and stearic acid. The mechanical properties were obtained with the potassium permanganate treatment.…”

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.
