Comparison of buckling capacity in CFRP composite plate and Hemp-Epoxy composite plate

Buckling in composite plates is a significant phenomenon that can significantly affect the integrity of the structure and the performance of composite materials used in various structures. This study investigates the buckling capacity of carbon fiber reinforced polymer (CFRP) composite plates compared to Hemp-Epoxy composite plates, focusing on their structural performance under compressive load. CFRP composites are known for their mechanical properties, including high stiffness and strength, which make them a suitable and popular choice in various industries. On the other hand, Hemp-Epoxy composites using natural fibers have good strength, and sufficient mechanical performance, and are a suitable and environmentally friendly alternative. This research examined composite plates with two different materials but with the same layup [۰/+۶۰/-۶۰/۰] and with the thickness of each layer of ۰.۳ mm. In this analysis, the Numerical method was used to obtain the buckling capacity for each composite plate in six different modes, and then the shape of buckling was determined in each of the modes. Finally, this study highlights the importance of considering the mechanical performance of composite panels under buckling and environmental effects when selecting materials for various structural applications.
