Abstract:

The aim to design a structure as light as possible, but without reducing its strength, stiffness and stability can be achieved by using sandwich composite components.The proposed project has innovative ideas based on: 1) identification of new mechanical interconnection solutions for the skins, using elements that cross the core of the sandwich, which are simpler, more cost efficient than those currently in use; 2) design of sandwich panels having an ultralight core spatially folded, or having double or triple core; 3) hybrid assembly solutions of sandwich panels having the core and skins made of dissimilar materials. Three new, original, types of lightweight plane sandwich panels, with increased strength, are proposed as follows: an aluminum one with “truss” type core, having a new geometry; a composite panel with carbon fiber reinforced skins and core having gradual properties made out of three or five layers of different polymeric foams; an orthotropic panel with core made out of polymeric tubes. The curved sandwich panels to be proposed represent innovative solutions with optimized geometries: a metallic cylindrical panel with a network type core made out of aluminum profiles intersected and built-in the polymeric foam, and a spherical panel made out of carbon fiber reinforced composite skins, joined together by using a “truss” type core. Experimental (static and cyclic testing of some joints) and numerical (linear and nonlinear 3D parametric FEM modeling for optimization) means of analysis will be used during the development of the project. Finally, the produced models made from these new sandwich composites will be tested experimentally. Registration of at least two requests of patents concerning the original construction solutions developed within the project will demonstrate the deliverables of this project. Internal homologation of the final products and technologies used by the manufacturing partner will prove the soundness of the engineering applications.
