It requires a different mind set to design with it than used for metals, for example any fibre reinforced structure is not really suitable for rivets, though non-expanding rivets which -can- be used are nowadays readily available. These are more for the benefit of traditional construction than suitableness-for-purpose though. How resilient a component is depends on design and material choice, as usual, it just needs a greater depth of knowledge to exploit than do metals. The Aeronautical industry is rightly very conservative... I have used carbon epoxy springs which are very light. Frank D.
