Hybrid 4D Braided Textiles for High Pressure Layflat Hoseline (MSC P 9052)

High pressure, layflat hoselines are used in Army water and fuel systems to transport bulk fluid over long distances to provide ease of storage, layout, set-up and retrieval. In order to meet the Army’s need for an improved hoseline with a higher working pressure (740 psi) and capability to meet all of the multifunctional performance criteria (including light weight, high pressure rating, durability, handling ease, abrasion resistance, fuel and chemical resistance, UV stabilization), new approaches to integrating higher strength fibers and optimizing fiber orientation in the hose jacket are needed. The innovation outlined in this proposal is the development and integration of two synergistic technologies that have the potential to meet all of the multifunctional performance criteria for layflat hoselines; viz., use of multi-material hybrid fiber bundles in a novel 4D (quadraxial) braided architecture. Feasibility will be demonstrated by conducting textile material modeling, parametric analyses, process demonstration trials and testing to characterize the performance candidate hybrid material configurations. The most favorable combination of fiber materials and orientations will be selected and a design concept for a compatible end fitting will be developed to establish a prototype hose design for manufacturing scale-up and performance testing in Phase II.
