The third layer is coupled to the second layer and has a third thickness (T3). The third layer includes an ultra-high molecular weight polyethylene (UHMWPE) composite or syntactic foam.

A thermally insulated panel includes a first skin, a second skin spaced apart from the first skin, and a core that is disposed between and bonded to the first skin and the second skin such that the core transfers loads between the first skin and the second skin. The core includes a porous filler material that has a vacuum drawn therein such that the core resists transfer of thermal energy through the panel. A cargo container including thermally insulated panels and a method of manufacturing the thermally insulated panels are also disclosed. In addition, a method of repairing a vacuum insulated panel is disclosed.
