The middle layer is a densified matt or batting having at least 10% by weight of carbonaceous fibers. The top and bottom layers are less densified matts or battings which have at least 10% by weight of carbonaceous fibers. Multiple composites may be secured together for increased protection against fire, sound and heat.
