Abstract
Hook and loop closures in Army uniforms have been identified as the critical sources of leaks in protective clothing/equipment, which limits the overall protective capability of the ensemble. We demonstrated during Phase I of this project that we can design and fabricate hybrid closure systems which incorporate areas of microfiber adhesive arrays inspired by the foot-hairs found on geckos which have hermetic sealing qualities. In this proposal, we build on the success of our Phase I project and propose approaches to further develop and optimize hybrid closure systems which achieve the same range of peel and lap shear strength performance as control hook and loop closures while demonstrating significantly better resistance to vapor permeation than such systems. We propose new methods to characterize the real world performance of these systems through repeated cyclic testing, contamination testing, and washability testing. Furthermore, we will develop new methods to integrate these hybrid closure systems into textiles and backings suitable for strategic needs identified by DOD stakeholders and demonstrate proof of concept mass production of these optimized materials. Success on the proposed technical objectives will allow for a transition to commercialization upon the completion of this Phase II project.
