Experimental Analysis and Numerical Modeling of Energy Absorption Capability and High Deformation Response in 3D-Printed Multilayer Panels

Abstract:

This study investigates the capability of additive manufacturing (AM) technology to produce sandwich composite structures through focusing on the 3D Printing process, experimental testing, and anticipated impact as energy-absorbent elements. The growing cost of manufacturing prototypes that use conventional methods has resulted in exploring the exploration of 3D printing as a viable alternative. The research problem addresses the challenges of manufacturing sandwich composites and the need for automation in the civil, mechanical, aerospace, and aviation industries. The study aims to investigate 3D-printed hybrid sandwich composite structures made of multilayer materials, conduct finite element analysis, produce specimens, conduct flexural and impact tests, and analyze the data. The proposed methodology includes preparation of the 3D printer, 3D printing of the specimen, inspection, finite element analysis, preparing the specimen for testing, conducting different impact tests, and data collection and analysis. The expected mechanical properties of the study lie in the potential for additive manufacturing to reorganize the adoption of sandwich composite structures for energy absorption purposes, reducing costs and automating the process.
