TL;DR: In this article, the polyurethane foam filled pyramidal lattice core sandwich panel is fabricated in order to improve the energy absorption and low velocity impact resistance, based on the compression tests, a synergistic effect that the foam filled sandwich panels have a greater load carrying capacity compared to the sum of the unfilled specimens and the filled polyurehane block is found.

TL;DR: In this paper, the vibration and damping performances of hybrid carbon fiber composite pyramidal truss sandwich panels with viscoelastic layers embedded in the face sheets were investigated. And the numerical simulation results showed good agreement with the experimental tests.

TL;DR: In this paper, a series of all-composite axial and circular corrugated sandwich cylindrical shells is manufactured using a novel hot press molding method, and a finite element model combined with modal strain energy approach is developed.

TL;DR: In this article, the bending properties and failure modes of carbon fiber composite egg and pyramidal honeycomb beams were studied and presented in terms of face wrinkling, face crushing, core member crushing and debonding.

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.
