Improved impact performance of marine sandwich panels using through-thickness reinforcement: Experimental results [PDF]

, 2010
This paper presents results from a test developed to simulate the water impact (slamming) loading of sandwich boat structures. A weighted elastomer ball is dropped from increasing heights onto rigidly supported panels until damage is detected. Results
