© 2015 Taylor & Francis This study assesses a bi-layer composite concept for mitigating the severity of injury due to translational blunt impact of an unprotected head at moderately high speeds. The concept comprises crushable foam and a stiff face-sheet on the impacting face. Approximate analytical models for acceleration–time histories of prototypical impact scenarios are used to guide the design. The key design variables probed experimentally are the crushing strength of the underlying foam and the tile size. The efficacy of the composite systems and the foams alone is ascertained through a series of drop impact tests with an instrumented head-form at a representative impact velocity (6.7 m/s, 15 mph), using three commercial viscoela...
