The implementation of natural fibre composites into interior trim continues to be developed by automotive suppliers mainly based on short fibres or natural fibre mats processed by compression moulding, injection moulding, thermoforming, and structural reaction injection moulding. The primary drivers for the selection of the appropriate process technology for natural fibre composites are the size and geometry of the part's performance, cost, and ease of manufacturing. Several factors must be considered in selecting a process. The process must allow good dispersion or distribution of the fibres in the composite, good compatibility between the hydrophobic matrix and hydrophilic fibres, minimum fibre degradation to insure optimum performance, control of fibre orientation. The control of moisture in natural fibre composites is of prime importance because it can result in significant performance reduction. It is quite costly to dry natural cellulose fibre and the ability to control and minimize energy input during this process is one opportunity foreseen with the processing of natural fibre materials. Similarly, the ability to eliminate water absorption during the servicing of natural fibre composite components is paramount in industrial applications.
