Abstract
In this paper, interaction between polyurethane foam and honeycomb structure in quasi-static penetration has been investigated experimentally. The structural elements used in this research were aluminum plate, aluminum 5052 honeycomb structure, and three types of polyurethane foam. The physical and mechanical properties of three types of polyurethane foams were determined. Honeycomb cores were filled with these foams. The quasi-static penetration tests were performed on foam filled honeycombs as well as unfilled honeycombs by flat ended penetrator. Failure mechanisms, ballistic limit velocities, absorbed energies due to penetration, damage modes and some structural responses were studied. Also, the effect of interaction between polyurethane foam and honeycomb structure in quasi-static penetration response in this honeycomb sandwich panel was discussed and commented upon.
