Flatwise and edgewise compression strengths of sandwich panel with silica aerogel mat

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

Structural Response of Polyethylene Foam-Based Sandwich Panels Subjected to Edgewise Compression

This study analyzes the mechanical behavior of low density polyethylene foam core sandwich panels subjected to edgewise compression. In order to monitor panel response to buckling, strains generated in the facesheets and overall out-of-plane deformations are measured with strain gages and projection moiré, respectively. A finite element (FE) model simulating the experimental test is developed. ...

Study on diffusion coefficient of benzene and ethyl benzene vapours in nanoporous silica aerogel and silica aerogel-activated carbon composites

In this study, nanoporous silica aerogel and silica aerogel-activated carbon composites have been synthesized using a water glass precursor by cost effective ambient pressure drying method. Equilibrium and kinetics of benzene and ethyl benzene adsorption on silica aerogel and its composites have been measured in a batch mode at tree weights of adsorbent. For the first time, the experimental dat...

Preparation and Characterization of Silica Aerogel Microspheres

Silica aerogel microspheres based on alkali silica sol were synthesized using the emulsion method. The experimental results revealed that the silica aerogel microspheres (4-20 µm in diameter) were mesoporous solids with an average pore diameter ranging from 6 to 35 nm. The tapping densities and specific surface areas of the aerogel microspheres are in the range of 0.112-0.287 g/cm³ and 207.5-66...

Comparison between flexural and uniaxial compression tests to measure the elastic modulus of silica aerogel

0022-3093/$ see front matter 2008 Elsevier B.V. A doi:10.1016/j.jnoncrysol.2008.06.014 * Corresponding author. Tel.: +609 258 5680; fax: + E-mail address: [email protected] (G.W. Sche The Young’s moduli of a set of silica aerogels have been measured by two techniques: 3-point bending and uniaxial compression. The data found by the two methods differ strongly. The uniaxial compression test g...
