Laminate and sandwich structures are typical lightweight elements with rapidly ex- panding application in various industrial fields. In the past, these structures were used primarily in aircraft and aerospace industries. Now, they have also found ap- plication in civil and mechanical engineering, in the automotive industry, in ship- building, the sport goods industries, etc. The advantages that these materials have over traditional materials like metals and their alloys are the relatively high specific strength properties (the ratio strength to density, etc). In addition, the laminate and...
