Synthesis of developed rice straw sheets and glass fiber-reinforced polyester composites

Abstract

In this study, a sheet of random rice straw fiber was developed. These rice straw sheets were used to reinforce polyester matrix. Synthesis of rice straw sheets and glass fibers as synthetic fibers-reinforced polyester composites were investigated. Several new stacking sequences were fabricated with random glass fiber mats with different areal densities (225 g/m2, 300 g/m2, and 450 g/m2) and rice straw sheets. The specific mechanical properties of these natural/synthetic fiber composites were investigated. Scanning electron microscopy was used to study the morphology of the fracture surfaces of the fabricated hybrid composites. Experimental results showed that specific tensile and flexural stiffness of rice straw fiber composite is better those obtained with glass fiber composites. The hybrid natural/synthesis composites with alternating glass fiber mat with areal densities 300 g/m2, and rice straw shows higher specific tensile strength than rice straw and other hybrid composites. Hybrid composites with high areal density on the outer surfaces yield a significant increase in flexural-specific strength and hardness as compared to other fabricated composites.

Improved mechanical properties of natural-synthetic hybrid composites

“…As G-fiber amount at the specimen surface increases, the hardness increases. Hardness values of [G 3 /SCB 2 /G 3 ], [G 2 /SCB/G 2 /SCB/ G 2 ] and [G/SCB/G 4 /SCB/G] are, respectively, 1.11, 1.03, 0.98 that of [G 2 /SCB 4 /G 2 ].This is in consistent with that obtained by Megahed et al[37].…”

Performance Evaluation of Jute/Glass-Fiber-Reinforced Polybutylene Succinate (PBS) Hybrid Composites with Different Layering Configurations

“…The other reason for the difference between the two stacking sequences is that glass fibers have much greater bending stiffness than natural fibers. During bending loading, the sample surface is greater than the center of the sample [ 32 ]. Subsequently, the top layer of the reinforcement layer controls the flexural strength and stiffness of the specimen.…”

Suitability examination of novel cellulosic plant fiber from Furcraea selloa K. Koch peduncle for a potential polymeric composite reinforcement

“…The second stage of elimination was noted from 280 to 400°C that represents the abolition of hemicellulose followed by celluloses, where, the drop at 280°C represents the complete degradation of hemicellulose and degradation of cellulose starts due to break down of glycosidic linkages. The extensive peak at 370°C denotes the removal of cellulose 1 or alpha cellulose from the material 46,101 . Perhaps, the less prominent drop displayed in the range of 450 to 640°C was inclined by the removal of lignin and charred residues 17 .…”

“…The extensive peak at 370 C denotes the removal of cellulose 1 or alpha cellulose from the material. 46,101 Perhaps, the less prominent drop displayed in the range of 450 to 640 C was inclined by the removal of lignin and charred residues. 17 Moreover, FSPF is gifted with a thermal stability of 370 C and highest maximum degradation temperature which are the desirable interesting properties that ensure the adaptability of corresponding fiber for high temperature required processing and applications.…”
