摘要：

The penetration resistance of various flexible multi-layer shielding concepts has been assessed in hypervelocity impact (HVI) tests at NASA Johnson Space Center (JSC) and at Southwest Research Institute (SwRI). The shields tested consist of 3 to 4 spaced bumpers made of ceramic cloth (Nextel(TM)) and a rear wall composed of high-strength cloth (Kevlar(TM). Low-density polyurethane foam is used between bumper layers and rear wall to deploy the bumpers after the shield is delivered to orbit and maintain bumper standoff while on-orbit. Ballistic limit equations have been derived from the HVI test results. These equations are being used to size shielding for an inflatable module, which is planned for potential use on Space Station.
