Sandwich panels are of great importance in the industry because of their high strength and low weight. Their potential abilities of cooling as well as vibration attenuation make sandwich panels even more attractive for multifunctional usage. The static, dynamic as well as the thermal properties of the sandwich panels are analyzed in the present work. Thereafter, each and every property serves as either the objective or the constraint in a multi-objective optimization using genetic algorithms. The sandwich panels are optimized in terms of the functions of load sustaining, heat dissipation and vibration attenuation at smallest possible weight. The relations between the above-mentioned functions and the weight of the panel are explored and the optimized dimensions of the sandwich panels are determined.
