Hovercraft skirt components are usually manufactured from nylon based fabrics coated with a suitable rubber compound. It is well known that such materials exhibit reduced levels of tensile strength and tear resistance when immersed in water for prolonged periods of time. Differences have been observed between fabrics of varying nominal weight. The relationship between the fatigue life of various coated fabrics and the degree of applied stress has been studied under both dry and wet conditions. The percentage loss of fatigue life after immersion in water is of the same order as that observed with tensile and tear strength. The fatigue life of a coated fabric is seen to be related to the level of applied stress, irrespective of the weight of the base fabric. The effect of fatigue on tear strength and rubber to fabric adhesion is considered, and the possibility of predicting the fatigue life of hovercraft components from the results of laboratory tests is discussed.
