Influence of Temperature on the Behavior of Sandwich Panels

Abstract Sandwich panels in the construction industry are used as roof and facade elements usually consist of two thin face layers steel a thicker core polyurethane (PU) or mineral wool between. The PU material is constantly being further developed. In addition to improvements physical properties, this development also leads changes mechanical properties. As result, design rules that were established for older foam systems must be reviewed at regular intervals. There great need research into temperature‐dependent behavior system. these elements, they directly exposed climatic conditions. High temperatures generated on cover sheets due solar radiation. rigid its properties temperature range. Tests small parts components show change stiffnesses strengths, well load‐bearing under elevated temperature. Consideration therefore importance. view continuous system, statements regarding from reconsidered.
