Abstract
Not Available Composite tubes for cryogenic cold-to-warm support structures with an isogrid structure will be developed that have lighter weight, lower thermal conductance, and equivalent compressive strength to those currently in use. Previous attempts to produce composite isogrid tubes, using the filament-winding process, have resulted in nonparallel and bent glass tows in the grid elements and considerable radial expansion (tow bending) at the grid nodes (intersections). Composite fabrication techniques will be emphasized to eliminate nonparallel glass tows in grid ribs and at nodes (intersections) and to minimize setup and winding costs. Several isogrid tube structures from two distinct glass/epoxy composite fabrication processes will be produced. Complete tubes having equivalent material cross-sectional areas will also be fabricated. Axial compression tests will be conducted for all produced types at room temperature and 77 K for comparison. Optimized isogrid structure and fabrication process will be assessed based on tube performance and fabrication cost.
