LOWVELOCITY IMPACT RESPONSE OF HOLLOW INTEGRATED 
SANDWICH COMPOSITES WITH ALUMINUM SKIN

Abstract

Abstract:

This paper presents experimental investigations on lowvelocity impact response of hollow integrated sandwich composites with aluminum skin by using dropweight method. The drop weight during impacting is obtained and recorded by acceleration transducer and the corresponding signal processing system. Based on the acceleration record, the impact force and impact displacement, energy absorption versus time can be calculated. The effects of aluminum skin on the impact characteristics such as peak force, contact duration, maximum deflection and absorbed energy are also examined. Results of the study indicate that the provision of additional aluminum skin enhances the damage resistance, such as contact stiffness, the peak load and initial damage of energy.

Key words: aluminum skin, lowvelocity impact, impact response, hollow integrated sandwich composites
