A tablet computer comprising:

• a display;
• a transparent cover member over the display and defining a touch-sensitive input surface;
• a housing at least partially surrounding the display and coupled to the transparent cover member, the housing comprising:
• a first housing member defining a first portion of a side surface of the tablet computer;
• and
• a second housing member defining a second portion of the side surface of the tablet computer;
• and
• a joining structure positioned between the first housing member and the second housing member and defining a third portion of the side surface of the tablet computer, the joining structure comprising:
• a composite plate comprising a plurality of ceramic-fiber reinforced layers;
• and
• a molded element bonded to the composite plate and to the first and second housing members.

An electronic device comprising:

• a transparent cover positioned over a display and defining a touch-sensitive input surface of the electronic device;
• a housing coupled to the transparent cover and comprising:
• a first housing member formed of a conductive material and defining a first portion of an exterior surface of the electronic device;
• and
• a second housing member formed of the conductive material and defining a second portion of the exterior surface of the electronic device;
• and
• a joining structure positioned between the first housing member and the second housing member and comprising:
• a molded element positioned between the first housing member and the second housing member and defining a third portion of the exterior surface of the electronic device;
• and
• a reinforcement plate at least partially encapsulated by the molded element and defining first and second major surfaces oriented perpendicular to the touch-sensitive input surface.
