Peach: Glad to see you retain your interest in space technology/exploration. A lot of spiritually ground-bound folks seem to thinks "space" is some peripherally unimportant niche but it is where 99.99999 and many more% of all of everything is located, outside the planetary womb we have yet to venture out of to live.
Wikipedia (the repository of all human knowledge) has a nice article on the Solar Probe Plus
http://en.wikipedia.org/wiki/Solar_Probe%2B
and a further link to carbon-carbon composite material as proposed for the heat shield

It looks like the plan is make a pass through the solar atmosphere and take nearly three months to cool off before doing it again.
Thanks for posting this. I had not heard of it previously.
