Front wheel well cover make/buy?

I don't know what they are called but they cover the access to the front shocks and wheel well, from the engine bay. They are made of a heavy black felt or gasket like material. Mine are very brittle and they look like they can be replicated easy enough, but I don't know what they are made out of exactly. What are my options? I can't find new ones because I honestly don't know what I should be searching for.
