摘要：

Absorber layers comprised of shear thickening fluid (STF) intercalated Kevlar(R) (STF-Armor(TM)) are integrated within the standard extravehicular activity (EVA) suit and tested for efficacy against both needle puncture and hypervelocity impact (HVI) tests characteristic of micrometeoroids and orbital debris (MMOD). An improvement in puncture resistance against hypodermic needle threats is achieved by substituting STF-Armor(TM) in place of neoprene-coated nylon as the absorber layer in the standard EVA suit. The prototype lay-ups containing STF-Armor(TM) have the benefit of being 17% thinner and 13% lighter than the standard EVA suit and the ballistic limit is identified in HVI testing. The results here demonstrate that EVA suit lay-ups containing STF-Armor(TM) as absorber layers offer meaningful resistance to MMOD threats. (C) 2015 Published by Elsevier Ltd.
