Can black fiberglass tissue be used for insulation in aircraft engines?

Black fiberglass tissue is not typically used for insulation in aircraft engines. Aircraft engines require materials that can withstand extremely high temperatures and harsh conditions. Instead, materials like aramid fibers, carbon fibers, and specially treated glass fibers are often used. These materials offer superior heat resistance, strength, and durability compared to black fiberglass tissue, which is not designed for such demanding applications.
