Low Velocity Impact of Sandwich Composite Plates
Impact and compression after impact properties of plain weave carbon fiber sandwich composites were investigated in this study. Impact tests were conducted on different sample types to obtain information about absorbed energy and force. The different samples consisted of foam filled and hollow honeycomb cores with four layer carbon fiber sheets on one or both sides. The impact and compression a...
متن کاملLow-velocity Impact of Sandwich Composite Plates
In this paper we investigate impact and compression after impact properties of plain weave carbon fiber sandwich composites. Impact tests were conducted on different sample types to obtain information about absorbed energy and maximum impact force. The different samples consisted of foam-filled and hollow honeycomb cores with four-layer carbon fiber facesheets on one or both sides. The impact a...
متن کاملA Theoretical and Experimental Study of Failure Maps of Sandwich Beams with Composite Skins and Honeycomb Core
Failure maps of sandwich panels such as beam, plate and shell are of great importance in designing such structures. In this paper, failure maps of sandwich beams with composite skin and honeycomb core are obtained. The effect of transverse shear in skins and core and the effect of double walls of honeycomb core have been taken into account. Shear deformation of skins and core are assumed to be ...
متن کاملBallistic Resistance of Honeycomb Sandwich Panels under In-Plane High-Velocity Impact
The dynamic responses of honeycomb sandwich panels (HSPs) subjected to in-plane projectile impact were studied by means of explicit nonlinear finite element simulations using LS-DYNA. The HSPs consisted of two identical aluminum alloy face-sheets and an aluminum honeycomb core featuring three types of unit cell configurations (regular, rectangular-shaped, and reentrant hexagons). The ballistic ...
متن کاملLS-DYNA Impact Simulation of Composite Sandwich Structures with Balsa Wood Core
The impact damage response of balsa core sandwich composite plates with S2-glass/ epoxy reinforced facesheets is evaluated by impacting them with a spherical steel projectile at single impact locations. The impact damage can significantly reduce the structural integrity and load bearing capacity of a composite structure. Under high velocity impact loading, laminated composites experience signif...
