An investigation on the processing of sisal fibre reinforced polypropylene composites

In this paper, a pre-impregnation technique has been introduced for the injection moulding of sisal fibre reinforced polypropylene (PP/SF) composites. The major advantasge of the pre-impregnation technique is that the PP/SF composites can be injection moulded with relatively lower barrel temperature, and therefore significant thermal degradation of the sisal fibres could be avoided. The resulting injection mouldings possessed lighter colour and no odor.
