Life Cycle Analysis [LCA] is the assessment of energy and other environmental impact and is specific to a product or component.
Broadly speaking, the more often it moves, moves fast or accelerates & decelerates, the more competitive a carbon fibre component will be in an LCA comparison with other materials.
This generally means that the LCA needs to be a Whole Life LCA and not a Factory Gate LCA in order to be competitive.
A good example is the passenger jet. it can be shown to have 20%
An LCA for a passenger jet will show a 20% saving when made with a great percentage of composites over the traditional all metal aircraft.
