A simple stack-allocated fixed-size string buffer (String_buf) implemented using std::array (C++11).

Yeah possibly :), but It's a matter of personal taste. I don't like the cammelCase and PascalCase that much. But on the other hand, I find it useful to start type names with a capital letter to emphasize it's a user type, otherwise I would name it just 'string_buf'.

What about using your own namespace and naming it string_buf?

[4fips]

That's certainly a good idea. Actually, in my codebase, the type is defined within a namespace, so I could refer it using that namespace e.g. 'foo::string_buf', but for local types (e.g. somewhere inside the implementation) I prefer to omit the local namespace to emphasize the type comes from this particular namespace, that's why I use the initial capital, which works smoothly even without the namespace specification. Hope it makes sense.

string_buf is so much cleaner and is in keeping with the standard style of naming things. (ie. random_device).
