Assessment of sandwich panels in construction Industries

الملخص

Composite sandwich plates are gaining increasing popularity in engineering practice, due to their – strength, high – stiffness – to – light – weight ratio. Durable materials are always desired by structure engineer. Composite materials of thermoplastics origin are blended with fiber glass or carbon fiber to produce a sandwich type composite, used in sandwich
panels is now becoming the structural material in engineering sciences and automobile parts in recent years also due to its light – weight and anti – corrosion properties. Although carbon
fiber reinforced-polymer meets the demands, but its anisotropy makes the connection of structural elements considerably weak which is the main cause that make its high strength not be utilized fully. However, the lower face lamina, the top face are made of polypropylene with (30%) fiber glass or (1%)carbon fiber composite, sandwich laminates are made of thin outer skin of fiber reinforced polymer adhesively bonded to a thicker core of foam. Composite materials in sandwich panels require knowledge of the mechanical behavior of the materials used for the facings and the core. In this work, different mathematical models will be used to evaluate structural analysis of the sandwich panels. The results of the experimental study have showed that reinforced thermoplastics composite will have potential benefits for the structures in future.
