Composite tanks for reusable launch vehicles and methods of fabricating thereof

A composite tank for a reusable launch vehicle, the composite tank comprising:

• a composite wall, having a first coefficient of thermal expansion, wherein the composite wall comprises:
• a first end;
• a second end;
• a central axis, which passes through the first end and through the second end;
• and
• a cylindrical interior surface;
• slosh baffles, formed from a second material, having a second coefficient of thermal expansion that is different from the first coefficient of thermal expansion,
• wherein:
• each of the slosh baffles is attached to the cylindrical interior surface of the composite wall,
• each of the slosh baffles is annular and is separated from the cylindrical interior surface of the composite wall by a radial gap, selected, in part, based on a difference between the first coefficient of thermal expansion and the second coefficient of thermal expansion, and
• the radial gap is configured to change responsive to changes in temperature of the composite tank;
• and
• attachment assemblies, coupling the slosh baffles to the cylindrical interior surface of the composite wall, and each attachment assembly comprising:
• stud assemblies, each bonded to the cylindrical interior surface of the composite wall;
• a first fitting, attached to the stud assemblies;
• and
• a second fitting, attached to the first fitting and comprising a second-fitting slot, extending radially relative to the cylindrical interior surface of the composite wall.
