“…The elongation at break decreased with increasing filler loading, possibly because the fillermatrix contact became less deformable (Neitzel et al 2011). The addition of silicon carbide particles to A. catechu fiber epoxy composites influenced the samples' flexural strength (Ashok et al 2023). In particular, the flexural strength of samples S4, S5, and S6 containing 10% silicon carbide was lower than that of samples without silicon carbide.…”

The physical and chemical attributes of Areca catechu fiber (ACF) were explored. ACF is attractive because of its high cellulose content at 63.2 wt%. The mechanical properties were evaluated for Areca catechu fiber-reinforced epoxy composites, in which silicon carbide (SiC) was used as filler. The studied properties included water absorption, flexural strength, impact strength, tensile strength, and hardness properties. The tensile and flexural properties improved when the filler content increased from 40 to 50 wt%, but further increment in the filler content reduced the strength values. The addition of SiC adversely affected the bending and flexural properties of the composites at 40 and 50 wt% filler content, but it positively affected the properties at 60 wt% filler content. The hardness of the composites increased with the addition of 10% silicon carbide. From the results of this study, it is recommended that the ratio of silicon carbide in the composite should not exceed 10 wt% due to agglomeration. The composites containing 10 wt% SiC can be used for outdoor applications such as decking, railing, garden fencing, cladding, and siding applications.

“…This may be because of the increase in filler, resulting in more particle‐to‐particle interface rather than nanoparticles interacting with the TF and matrix. Ashok et al 37 conducted a study on the impact of adding lignite fly ash to calotropis gigantea stem fiber epoxy composites. They found that the optimal quantity of nanoparticles led to an increase in shear strength.…”

This study is focused on the investigation of the mechanical characteristics of Timoho fiber (TF) epoxy composites with graphene as the filler material, both experimentally and numerically, for high‐velocity impacts. The composites were prepared by the compression molding process with varying wt.% of graphene. An experimental approach was undertaken to study the behavior of the composites under different wt.% of graphene. To validate the results obtained in the experimental approach, numerical studies were conducted. It was observed that there was an enhancement in the mechanical properties with the addition of graphene. For tensile strength, there was an increase of 33.17% when comparing the controlled sample (0% graphene) and the sample with 2% graphene content. Subsequently, there was an increase of 36.48%, 58.02%, and 29.79% when comparing the controlled samples and samples with 2% graphene, respectively, for flexural, impact, and interlaminar shear strength (ILSS). However, it was observed that after the addition of 2 wt.% of graphene, the mechanical strength decreased due to the agglomeration of graphene inside the composite, which was confirmed using the SEM analysis. For the numerical study, ANSYS workbench was employed, and simulation was conducted using finite element analysis (FEA) for the tensile and flexural test. The numerical findings were found to be reasonably close to the experimental values, with variations ranging from a minimum of 2% to a maximum of 15%. In the design of experiments, Taguchi's approach was used to determine the effect of a variety of parameters on the tensile behavior of the TF epoxy composites.Highlights 2 wt.% of graphene was observed to be the optimum concentration of graphene. The decline in mechanical properties was observed at 3 and 4 wt.% of graphene. Agglomeration of graphene filler in the composite was confirmed using SEM. ANOVA showed that wt.% of graphene made the top contribution to tensile strength. The nanographene‐incorporated TF composites can be used for lightweight applications.
