A moldable heat shield with a needled nonwoven core layer and needled
nonwoven shell layers. The core layer has a blend polyester staple fibers
and low melt polyester staple fibers. The shell layers have a blend of
staple fibers of partially oxidized polyacrylonitrile, and staple fibers
of polyester, and staple fibers of a low melt polyester. The layers are
needled together such that fibers from the core layer do not reach the
outer surfaces of the shell layers. The shell layers are calendared such
that an outer surface layer is formed thereon, which provides the
moldable heat shield with a water and oil resistant surface.
