Sandwich-structured composite

TL;DR: In this paper, a method for rapid fabrication and prototyping of low-density carbon fiber sandwich panel cores based on laser beam cutting (LBC) was presented, where lattice core constructions with oblique and vertical strut morphologies were fabricated from two fiber orientation architectures.

TL;DR: In this article, a group of metallic aluminum foam-cored sandwich panels (AFSPs) were used as vehicle armor against blast loading, and the dynamic responses of the AFSPs with various combinations of face-sheet materials were analyzed using LS-DYNA.

TL;DR: In this article, the impact behavior of sandwich beams with a functionally graded core was analyzed and it was concluded that for sandwich beams having functionally graded cores, the maximum contact force increases and the maximum strain decreases compared to those of a homogenous core.

TL;DR: In this article, a 3D sandwich structure with foam core reinforced by composite columns is designed and manufactured, and failure modes are investigated under the optical microscope under bending, out-of-plane compressive and shear loadings.

TL;DR: In this article, the flexural behavior of glue-laminated composite sandwich beams with a view of using this material for structural beams was investigated and the results indicated that the bending stiffness of flatwise specimens converges to that of the edgewise specimens with increasing laminations.
