Abstract The thermal analysis is performed on a heated Inconel 617 honeycomb-core sandwich panel. Sandwich panel is supported at its four edges with spar-like sub-structures that acted as heat sinks, which are generally not considered in the classical analysis. One side of the panel is subjected to a heat flux on the surface. Two types of surface heating were considered: (1) hexagonal honeycomb...

An experimental investigation was conducted to evaluate the dynamic performance of E-glass Vinyl Ester composite face sheet / foam core sandwich panels when subjected to pre-compression and subsequent blast loading. The sandwich panels were subjected to 0 kN, 15 kN and 25 kN of in plane compression respectively, prior to transverse blast wave loading with peak incident pressure of 1 MPa and vel...

We present a novel method for fabricating carbon fiber composite sandwich panels with lattice core construction by means of electrical discharge machining (EDM). First, flattop corrugated carbon fiber composite cores were fabricated by a hot press molding method. Then, two composite face sheets were bonded to each corrugated core to create precursor sandwich panels. These panels were transforme...

By Heming Zhang Alwin, M.S. Washington State University December 2002 Chair: John C. Hermanson Structural insulated panel (SIP) use in residential building began in the 1950s. Over the last two decades, greater SIPs usage has been encouraged by many factors. ICBO ES provides “Acceptance Criteria for Sandwich Panels AC04” for sandwich panels recognition. The criteria require that full-scale pane...

Lately, a new technical solution, pre-compressed joint sealing tapes in precast concrete sandwich panel facades, has been introduced Sweden. Although the consequences of performance failure can go far beyond component, affecting building, introduction gained little attention terms risk assessment literature and industry. Instead, reference cases are used as verification without formal evaluatio...

In recent past, the authors developed an innovative modular system for low rise building made by structural sandwich panels. This was conceived with focus on rationalization of construction process and thermal efficiency building. Thus, precast panels comprise two outer Steel Fibre Reinforced Self-Compacting Concrete (SFRSCC) layers, a insulation material Glass Polymer (GFRP) connectors. Studie...

A series of drop weight tests were conducted to evaluate the dynamic flatwise compression strength and flexural strength of sandwich panels with a novel core structure. This sandwich core material, known as Norcore, consists of interconnected cells in a unique configuration of truncated pyramid with sloping cell walls. Core materials made of thermoplastic including virgin Lexan, polycarbonate, ...
