Natural fibre composites (NFC) are gaining interest in manufacturing because they address some of the
environmental problems of traditional composites: use of non-renewable resources, and large impacts
related to their production and disposal. Since natural fibres are not yet optimized for composite
production, it is crucial to identify the most appropriate applications, and determine the optimal fibre/
matrix ratio. A methodology is proposed for early-stage decisions support on selection of bio-composite
materials. Results help identify the application with the largest reduction in environmental burden and
show that the fibre/matrix combination with the lowest environmental burden also has the best
mechanical properties.
