Abstract

This paper presents a study on corrugated design based 3D printed sandwich panels subjected to quasi-static compression. The study focuses on the investigation of unique corrugated triangular and trapezoidal core de�signs. Effects of core thickness, skins, height of core and the contact area between core and skins on the me�chanical properties of the sandwich panels were investigated through a series of experimental tests. Biodegradable poly-lactic acid thermoplastic filaments reinforced with chopped carbon fibers were used to print sandwich panels. The test results have shown that the compressive strength and energy- absorbing capability of the sandwich panels studied increase rapidly with increasing core thickness. Also, an increase in the contact area between the core and skins results in better mechanical properties.
