A sandwich structure (composite) consists of three main parts: two thin, stiff, and strong faces and a thick, light, and weaker core. The faces are adhesively bonded to the core to obtain a load transfer between the components. The basic advantage of sandwich structures (composite) is its high strength to weight ratio, high resistance to corrosion and impact, good insulation to acoustic and heat. This thesis research is based on Madflex, an innovative technology in the field of sandwich that after receiving some changes in the core geometry, it enables this sandwich to be flexible, even rollable in one direction of bending and in the opposite side, it is totally rigid.
