摘要： A composite spring-damper and method of making the same. The spring-damper has an exposed fabric layer free of structural foam and curable resin. A core formed of resilient foam defines a spring shape and a fabric layer (15) disposed on an outer surface of the core is attached to the foam core by means of the foam having substantially filled only interstices (19) of an inner portion of the fabric layer, without substantially penetrating an outer portion of the fabric layer, whereby the fabric layer of the composite spring-damper may thereafter be substantially completely saturated with a curable material for lamination to another structure. An attached reinforcing fabric layer (13) may be provided on the exterior surface of the fabric layer, in which case the fabric layer may be entirely saturated and only the attached fabric layer substantially free of foam.
