Summary: This investigation explored the dynamic mechanical properties of Indian almond - Kenaf fiber composite and analyzed the effect of stacking sequence. The experimental results showed that the kenaf fiber composite exhibited superior storage modulus and loss modulus values compared to other composites due to the high stiffness of kenaf fiber and better bonding between the matrix and fiber. Among the hybrid composites, the Kenaf/Indian almond/Kenaf composite displayed higher moduli due to the presence of two layers of high stiffness kenaf fiber. The thermal stability of the composites followed the order of Kenaf > Kenaf/Indian almond/Kenaf > Indian almond/Kenaf/Indian almond > Indian almond. The Indian almond fiber composite and Indian almond/Kenaf/Indian almond composite showed good damping properties due to the higher mobility of polymer chain. The cole-cole plot indicated that all the fabricated composites had heterogeneous structures, with the kenaf fiber composite displaying the highest heterogeneity among all materials. The modeling of storage modulus and damping factor showed good agreement with the experimental results.

Summary: Natural fiber reinforced hybrid polymer composites have better mechanical properties compared to synthetic fiber composites, and kenaf fiber has shown great potential for technical applications. In this study, the mechanical properties of kenaf and kapok fiber reinforced hybrid polyester composites were investigated. The composite specimens were prepared using a simple hand lay-up technique and tested according to ASTM standards. The results showed that the composite with equal contribution of kenaf and kapok fiber reinforcement exhibited high tensile and impact strength. However, an increase in kapok fiber content led to a decrease in bending strength and bending modulus of the composites. SEM analysis was conducted to examine the fractured surfaces of the specimens.

Summary: Jute, kenaf, and banana fiber reinforced epoxy hybrid composites with different stacking sequences were fabricated by compression molding techniques. The mechanical properties and physical parameters of the composites were investigated. The results showed that pure banana composites had the highest tensile, flexural, interlaminar shear strength, and hardness values. KBJJBK and BJKKJB hybrid composites also exhibited high strength and hardness, as well as low water absorption and thickness swelling properties. These hybrid composites are suitable for automotive structural applications.

Summary: Thermogravimetric analysis of Indian almond leaf reveals four decomposition stages, with mass loss primarily occurring in stage II due to the simultaneous decomposition of cellulose, hemicellulose, and lignin. Increasing heating rate leads to a shift in the pyrolysis curve, lower mass loss rate, and presence of more inert content. The calculated average activation energies of different models fall within the range of reported leaves.
