Popular sources, like Vintage Space and New Scientist, allege that the Chinese experimented with (oak?) wood ablative heat shields for manned reentry vehicles in the 1960s, but I have not been able to find any technical information.

Does anyone have translated English papers from the original project, or intelligence reports? Chinese documents would also be valuable, I would be willing to have them translated.

    $\begingroup$ Take a look at this answer, there are some pix here too. For a tl;dr, search for "oak" in here: astronautix.com/f/fsw.html and open this book in books.google.com and search for "oak": China's Space Program - From Conception to Manned Spaceflight Here is the book also: springer.com/gp/book/9781852335663 $\endgroup$
