Characterisation of the mechanical and thermal degradation behaviour of natural fibres for lightweight automotive applications [PDF]

open access: yes, 2013
It is well established that light-weighting of automotive parts leads to reduced carbon emissions over vehicle lifetime. Mineral fibres and fillers have a relatively high density and may require high levels of energy in their production, resulting in a ...
