AVCOAT 5026-39 is a NASA code for a specific ablative heat shield material created by Avco[1][2] (acquired by Textron in 1984).[3]
It is an epoxy novolac resin with special additives in a fiberglass honeycomb matrix. In fabrication, the empty honeycomb is bonded to the primary structure and the resin is gunned into each cell individually.[4]
