1. A process for the fabrication of an inflatable deicer boot comprising the steps of:

  • providing a plurality of elastomeric tubular members having passageways therethrough defined by a fabric coated on one side with a natural rubber nonflowable under conditions whereby the rubber is vulcanizable, the natural rubber being at least 1% by weight cross-linked natural rubber, and an interior wall surface of the tubular member defining the passageway and being defined by the fabric,mounting the plurality of tubular members in a laterally spaced realtionship on a lower, vulcanizable elastomeric ply of material;

    laying a manifold ply having a central passageway therein across said tubular members whereby said central passageway in said manifold ply communicates with in said tubular members;

    overlaying said lower ply, tubular members and manifold ply with an upper ply of vulcanizable material to form the deicer boot;

    drawing a vacuum on said manifold and passageways said passageways in said tubular members;

    vulcanizing said deicer boot into a unitary structure; and

    connecting an inflation valve to said manifold through said upper ply.
