Experimental Study of Lightness Factors and Loading Abilities of Sandwich Structures

The objects of interest are glass-fiber-reinforced-plastics (GFRP) null null null and null carbon-fiber-reinforced-plastics (CFRP) composite sandwich shells with a foam core.  Such a structure has been common since the beginning of composite applications in aircraft construction. The strength-lightness factors of typical sandwich structures are large in comparison to laminate structures without a foam core.  However, the loading abilities of...
