Evaluation of impact, thermo-physical properties, and morphology of cornhusk fiber-reinforced polyester composites

This study aims to investigate the thermo-physical and morphological morphology of cornhusk fiber-reinforced polyester composites. The content of corn husk fiber (CHFs) has been varied, namely 20, 30, 40, and 50 (% vol.) in the polyester composite, respectively. The hot press technique has been used in the manufacture of these composites, then properties were investigated through thermo-physical tests including differential scanning calorimetry, thermogravimetry, Fourier transforms infrared, impact strength properties, and morphology using SEM. The results showed that the composite containing 30% CHF (KJP2) was found to have the most optimal impact strength (4.25 KJ/m(2)), and the best thermal resistance properties were found in the KJP3 composite, compared with other composites; due to CHF dispersion and good interfacial adhesion between CHF and polyester. SEM images of the fracture of the impact test specimens of the composites show better interfacial bonding between CHFs and polyester.

Automated summary

This study investigates the thermo-physical and morphological properties of cornhusk fiber-reinforced polyester composites. The results show that the composite with 30% corn husk fiber has the optimal impact strength and the best thermal resistance properties due to the dispersion of corn husk fibers and good interfacial adhesion with polyester.
