Evaluation of mechanical performance and failure modes of sandwich structures for transport industry

Abstract

This paper deals with an evaluation of mechanical performance of specific sandwich constructions. Composition of prepared construction was chosen with respect to area of application - transport industry. In total, three plastic core materials were selected with different density and cell shape. Materials were tested in three-point bending configuration at room and elevated temperature. Conducted research provided useful information of flexural performance and showed specific failure modes for tested sandwich structures.
