Today , automated methods of production and a much larger selection of facing materials , cores and adhesives have permitted the production of composite sandwich panels that can be tailored to meet a vast range of requirements in diverse fields of application .
It ’ s been long understood that two materials with a lighter material in between them increases the stiffness and strength of a structure while keeping weight and costs low .
It also allows for greater freedom of design . In transportation , lower weight enables higher payloads .
Rising fuel costs and increasing awareness about the importance of environmentally-friendly solutions has meant innovative construction methods like sandwich panels are becoming more popular for structural design .
