Sandwich-structured composite

TL;DR: In this paper, upper and lower bounds for the effective transverse shear moduli of a chevron folded core used in sandwich construction are analyzed and compared to finite element computations.

TL;DR: In this paper, the impact-induced damage on the residual flexural strength of honeycomb core sandwich panels with different structural configurations was evaluated by combining the experimental, numerical and theoretical methods.

TL;DR: In this paper, a study about the influence of through-thickness tufted fibres on compression and bending properties of sandwich structures is presented, where an experimental study was developed which included edgewise compression and 3P bending tests of Tufted and non-tufted sandwich panels made of carbon/epoxy and E-glass/EPoxy face-sheets, PVC and polyurethane foam cores, with different tufting densities.

TL;DR: In this paper, the authors investigated the creep response of laboratory made natural fiber-reinforced thermoset polymer composite face/honeycomb core sandwich panels in a period of 30 days in ambient conditions and at 65% relative humidity.

TL;DR: In this article, an autodyn-based numerical simulation was conducted to investigate the dynamic response of core sandwich panels to air blast loading in an explosion tank considering three levels of blast loading and found that the maximum deflection, core web buckling and core compaction increased as the decrease of stand-off distance.
