This Phase I SBIR contract will apply the principles of integrated materials computational engineering the the design and fabrication of a integral thermal protection system cyrogenic storage tank. ANSYS modelling will be carried out to sub-optimize the materials properties necessary for an integrated structure-insulation-thermal protection system using miltilayered thermally insulating syntactic foams core structure. By combining structural and insulation performance in a high temperature structure, a 65-100% reduction in parasitic thermal protection weight can be achieved. multilayer sandwich panel coupons will be fabricated and characterized for cryogenic to high temperature properties and thermal cycle response to validate the model, and manufacturing pathfinding efforts will be conducted for production of curved multilayered sandwich panels. structures.
