%X Study of the deformation mode and the failure mode of Nomex honeycomb sandwich structure subjected to different impulses is presented in this paper. In experiment, projectiles were used to provide different impulses for Nomex honeycomb sandwich beam, and laser displacement sensor was used to measure the back-facesheet deformation displacement of specimens. Effect of the projectile impulse and the facesheet thickness on the resistance to impact was analyzed and the energy absorbing capability of core and facesheet was numerically analyzed based on the experiment data. Experimental results indicate that sandwich beam can effectively improve the ability to resist deformation by increasing facesheet thickness, about 50% energy is absorbed by the core during impact, and more energy is absorbed by the core as impulse increasing.
