The elongate composite structure is composed of a base material (12), such as hard silicone, making the composite structure self-supporting. Property improving means (14) is provided for improving at least one physical property of the composite structure other than self-supporting properties, such as fatigue resistance, liquid impermeability, aggressive body cells resistance, anti-friction properties and lifetime.</p> |
