Method & Evidence

AimTo investigate the joining behavior of natural fiber-based epoxy laminates using different joint configurations and adhesives, and to validate these findings using Finite Element Analysis (FEA).

MethodExperimental investigation combined with Finite Element Analysis (FEA).

ProcedureComposite laminates were fabricated using jute, sisal, and hybrid fibers with epoxy resin. Various joint configurations (single lap, double-strap butt, scarf) were tested with two types of epoxy adhesives. Tensile testing was performed to determine joint strength. 3D assembly models were created in SOLIDWORKS, and FEA was conducted in ANSYS to analyze maximum shear stress and total deformation. FEA results were compared with experimental data.

ContextAdhesive joining of natural fiber-reinforced composite materials for potential use in non-structural components.

Strengths & Limitations

Strengths

+Combines experimental testing with computational modelling for robust validation.
+Investigates multiple joint configurations and adhesive types.

Limitations

The accuracy of FEA is highly dependent on the quality of the input data (material properties, mesh density) and the assumptions made in the model. Real-world conditions may introduce variables not accounted for in the simulation.

Reliability & validity

The study's validity is strengthened by the direct comparison of FEA predictions with experimental results. Reliability would be assessed by repeating experimental tests multiple times to check for consistency in outcomes.
