Static and Dynamic Analysis of Basalt Fiber Reinforced Sandwich Composite Laminates with Aluminium Honeycomb Core

Honeycomb core sandwich composites are extensively used in aerospace and other industries due to its less weight, high in-plane, radar transparent and design flexibility properties. The most common type of failure occurs due to core compression which leads to adhesive failure on the structure. This paper studies about the compressive behavior of honeycomb core sandwich composite which is made up of basalt fiber as face sheet and Aluminium as core in the sandwich structure. In order to reduce the experimental cost and have a clear idea on real life problems modeling and simulation type of work have got well importance. In this analysis the modeling of sandwich composite is done in CATIA. After that the static analysis of beam and plate structure of sandwich composite is performed in FEM environment (ANSYS), by taking the face sheet of equal thickness and different thickness of core. Finally the total deformation is obtained for both the cases by applying different uniform distributed load and point load on the composite structure in ANSYS by importing the solid model. Again modal analysis of sandwich structure is done in ANSYS, which determines the various characteristics like natural frequency, mode shapes for a static load condition.
