Abstract

This study employs ABAQUS/Explicit to simulate the mechanical behavior of composite honeycomb sandwich panels under flat crush and lateral compression, considering both unfilled and filled structures. Utilizing the Johnson-Cook model for aluminum alloy and a crushable foam model for the filled matrix, predicting damage evolution with Hashin criteria and a cohesive zone model. The impact of reinforcement methods, including short carbon fibers and silicon dioxide particles at 1% content, on the compression strength and energy absorption of infused panels is analyzed. Results show that these reinforcement methods significantly improve the structural performance of composite honeycomb sandwich panels, particularly their compression strength and energy absorption capabilities. offering an effective enhancement strategy. However, additional studies are needed to optimize content and interaction mechanisms between reinforcements and foam matrix is recommended.
