Structural behaviour of composite sandwich panels

Designing a prefabricated sandwich composite roofing system Made up of resisting facings and light-weight concrete core with truss-shaped connectors

In this paper, a new roofing system is introduced, which is constructued using the precast composite sandwich panels. This roofing sandwich panels system consists of three kinds of precast concrete sandwich panels including capital panels, beam or between columns panels, and slab or middle panels. The panels are composed of three layers; A high strength reinforced concrete top layer. A thick la...

Edgewise Compression Behavior of Three-Dimensional Integrated Woven Sandwich Composite Panels

Experimental Study of the Bending Properties and Deformation Analysis of Web-Reinforced Composite Sandwich Floor Slabs with Four Simply Supported Edges.

Web-reinforced composite sandwich panels exhibit good mechanical properties in one-way bending, but few studies have investigated their flexural behavior and deformation calculation methods under conditions of four simply supported edges. This paper studies the bending performance of and deformation calculation methods for two-way web-reinforced composite sandwich panels with different web spac...

Study of the vibro-acoustic behaviour of composite sandwich structures by means of a novel test setup

In this paper an experimental-numerical approach is presented to tackle the vibro-acoustic characterization of composite sandwich structures. A novel experimental setup allows for fast and comprehensive understanding of the NVH behaviour of composite sandwich panels. This information can then be further exploited in numerical model updating and design tools for optimized solutions. Experimental...

Shear and bending performance of carbon fiber composite sandwich panels with pyramidal truss cores

Structural performance in direct (pure) shear and three-point bending was investigated for sandwich panels with a carbon fiber pyramidal truss core. Analytical estimates for sandwich panel strength for each loading condition were presented for possible competing failure modes. In the experimental part of the study, pyramidal truss cores were made using the hot press molding technique and then a...
