This would not be the first time wood was used to construct a space craft. The Russians used wood for their heat shields. Wood is a good heat insulator and requires a great amount of energy to vaporize - converting kinetic energy to heat energy. The vapor would then be pushed away from the spacecraft before burning.
Chinese supposedly had brine soaked oak heat shields for experimental manned capsules in 60s
Lotta laffs about that, but it probably works just fine
Certain plastics are made from chemicals from wood.
Your toothpaste? It has stuff in it from wood.
We CAN NOT survive on this earth without the combination of products from the big three-Farming, Logging and Mining, and I consider oil drilling a type of mining.
Wood was also used in the interiors of early Soviet spacecraft. This played havoc with launch weights because of the loss or gain of moisture in the wood from differences in seasoning and storage conditions as spacecraft were awaiting launch.
