Abstract
Abstract A heat shrinkable fabric is impregnated with a plastic or resin material to reduce its air permeability prior to any assembly of the fabric on an aircraft. After the fabric has been pre-impregnated it is then available for sale as an aircraft covering. A purchaser need only cover the aircraft and heat shrink the same, applying thereafter filler and/or paint coatings as desired.
