| چکیده | ||
| Composite sandwich structures are becoming more and more popular in the sports, automotive and aerospace sectors because of their excellent strength-to-weight ratio. However, more research is required to fully understand their stiffness properties and the accuracy of predictive modeling. By simulating and examining two different sandwich structures made of Carbon Fiber face sheets and Kevlar Honeycomb core material represented as an equivalent solid, this study fills this gap. Gibson and Ashby model has been adopted to find the equivalent orthotropic properties of core because this model provides a balance between precision computational efficiency and suitability for Honeycomb cores, guaranteeing accurate stiffness predictions and facilitating simple engineering design implementation. Experimental stiffness values of 529.74 N/mm and 479.98 N/mm for the two configurations are obtained by performing “Three-Point Bend Test” on the manufactured panels. With an accuracy deviation of about 0.84 % the numerical model predictions closely resemble the experimental findings, demonstrating the model’s dependability in representing the material’s static behavior. The sandwich structure demonstrates a stiffness of about 565 N/mm, suitable for high-load applications in aerospace and automotive sectors. The stiffness of Kevlar honeycomb core sandwich panels can be accurately predicted using numerical modeling validated by experimental results. | ||
