W. L. Gore & Assoc. (Pleinfeld, Germany) has expanded its line of GORE SKYFLEX aerospace materials to improve protection against chafing and abrasion in rotary and fixed-wing aircraft surfaces. Surfaces exposed to flight environments are subjected to mechanical forces that can result in damage, the effect of which is to decrease the strength and fatigue life of panels, structures or internal floorboards. In antichafe applications, the products help minimize vibration force and reduce the abrasive effects of foreign debris that gets lodged between surfaces. In aircraft applications, such as access panels, fuel bladders, tail booms and transmission panels, mechanical wear from vibration can cause small particles to become trapped at an interface, resulting in chafing, pitting and scoring. Gore’s soft, durable materials are chemically inert and resistant to aircraft fluids, and thereby minimize the potential for corrosive effects. For edge protection, the materials are engineered specifically to prevent abrasion and cut-through damage from composite floorboard edges and to reduce the likelihood of corrosion. Because the SKYFLEX materials are reportedly more durable than fiberglass tapes, these materials protect edges by isolating carbon fiber and other components that are galvanically dissimilar. These lightweight, highly conformable materials also are said to be easy to install because of their single-component construction, and they are expected to simplify maintenance because they are easy to remove for inspection.
