Vectran webbing uses pdf Vectran® is an ideal choice for low-stretch webbing, offering enhanced stability and minimal elongation under tension. Vectran did not retain its strength as well as aramids when tested at high temperature (Fig. William Doggett. However, Vectran® does poorly with UV-ray exposure, which causes strength loss . Material Pre-Tensioning . Pre-tensioning of the webbing strips began with attachment of the bottom of each strip to the shear test frame using a ‘dead man’ gripping method. 8). Time-Dependent Behavior of High Strength Kevlar and Vectran Webbing. arm plates were thin Vectran shims used to ensure uniform contact along the length of the frame. This is consistent with the thermoplasticity of Vectran. 2. Inflatable habitats achieve the maximum livable volume for the minimum launch weight because they use woven structures packed into a small volume that can be pressurized to reach its full dimensions in space. baseline architecture for these studies. EXPERIMENTATION . This work is part of the effort to better characterize and compare the two materials while using the same webbing architecture. Table 2 lists the Mil-T- Again,Vectran retained tensile strength after exposure and was superior to aramid fiber. Kevlar was used in Transhab primarily due to its heritage, but Vectran has shown promise as a comparable material with better creep properties. 5 MECHANICAL PROPERTIES OF Vectran™ FILAMENT YARN (AVERAGE) Vectran™ 0 X 0 Y Yarn Cycles-to-Failure Vectran™ T97 115,113 Aramid 1 5,114 Aramid 2 40,666 Aramid 3 1,383 PBO 23,821 Test Conditions: Tinius Olsen tester, ASTM D2176-97a, modifi ed for yarn, 2 kg weight FLEX FATIGUE RESULTS ON 1500D YARN 2mm Cord Cycles-to-Failure Vectran™ T117 Download Free PDF. 2014, 55th AIAA/ASME/ASCE/AHS/ASC Structures, Structural Figure 1: Webbing SHM Applications, (a) Aircraft safety harnesses, (b) Inflatable space habitat Vectran webbing restraint layer. Six strips of webbing material were laid Vectran® webbing and straps also have good flex fatigue properties, meaning the fibers can be bent repeatedly without compromising the fiber. Figure 9 displays the relationship between Vectran physical properties and temperature over time. qpc hjrz jnq byptj jdwz oyisqyu igt zjtfai tyj flpwvgk
