An experimental study has been conducted to evaluate the importance of bumper materials selection upon the performance of two-component hypervelocity impact bumper shields. Several bumper materials were found that were equally effective on a mass per unit area basis. Bumper material effectiveness dropped rapidly with bumper material density when this density was below 2 gmcc. Optimum bumper thicknesses exist for minimizing total shield weight for all bumper materials investigated. All of the data obtained in this study can be explained by an analysis of the states of the impacting pellet and bumper material within the debris cloud projected behind impacted bumpers. The most important parameter controlling shield operation is the state of the pellet material in the debris cloud.
