The use of natural fiber composites in the fatigue prone structures is limited due to the lower strength and durability when compared to the carbon fiber reinforced polymer composites. The present work focuses on improving the bending cyclic fatigue strength (CFS) of the sugarcane fiber reinforced epoxy composite (SFRPC) by a novel treatment method. The treatment has increased up to 40% fatigue life of SFRPC by fiber and interface strengthening. The fatigue life was evaluated using the standard bending cyclic fatigue test. The SFRPCs were prepared using a specially designed compression molding setup by the hand layup method. The sugar cane fibers (SCF) were treated using the waste glass powder and PVA adhesive. The statistical analysis was conducted to observe the effect of the treatment method, the load ration (R) on CFS of treated/untreated SFRPC. A comparison of CFS of SFRPC (treated/untreated) with CFRPC is presented based on the author's previous work. A finite element based model was constituted for predicting the elastic properties of SFRPC (treated/untreated) at different fiber proportions. Additionally, a finite element (FE) model was constituted using the transient analysis in ANSYS (Explicit Dynamics Module) for obtaining the deformation and Von Mises stress at different R for the corresponding life of the treated/untreated SFRPC sample. A theoretical explanation for improved fatigue behavior of SFRPC was presented using scanning electron microscopy (SEM) micrographs and FE results collectively. The stress-strain-life relations for treated/untreated SFRPC were established. It was found that the shear yielding resulted due to the fracture of the outer glass layer of the SCF resulted in the higher CFS of the treated SERPC.read more

A review of recent developments in natural fibre composites and their mechanical performance
Abstract: Recently, there has been a rapid growth in research and innovation in the natural fibre composite (NFC) area. Interest is warranted due to the advantages of these materials compared to others, such as synthetic fibre composites, including low environmental impact and low cost and support their potential across a wide range of applications. Much effort has gone into increasing their mechanical performance to extend the capabilities and applications of this group of materials. This review aims to provide an overview of the factors that affect the mechanical performance of NFCs and details achievements made with them.
