Buckling and post-buckling analysis of hybridized natural fiber reinforced polymer laminates.

Natural fibers are derived from plants and trees that have no negative impact on the environment. Composite materials have been utilized for many years. Fibers have been used in composite materials for a long time. The use of natural fibers has decreased as synthetic fibers such as glass fiber reinforced polymer have shown potential benefits. Natural fibers, on the other hand, have some drawbacks, such as poorer durability and strength. Recent advancements in the fiber business, on the other hand, have improved the qualities of natural fibers by properly treating them allowing them to compete with synthetic fibers in terms of durability and strength. In the present study, two types of natural fibers are considered, and they are sandwich hybridized (SH) to attain the properties of the constituent fibers in the whole laminate. The natural fibers considered are hemp and jute. In terms of tensile strength, hemp fiber is slightly stronger than jute fiber. A SH laminate with quasi-isotropic layup sequence is modelled analyzed for buckling and post-buckling under uniaxial compressive loading condition. A finite element method-based software ABAQUS has been used for the analysis purpose. It has been observed that SH laminates in which hemp fibers on the surface and jute in the core region have better performance compared to SH laminates in which jute fibers on the surface and hemp in the core regions. It's worth noting that hybridization has a significant impact on laminate modelling, which can be employed in structural applications. [ABSTRACT FROM AUTHOR]
