**Abstract**
 Polymeric-filled composites and melt blended composites of Kevlar pulp/HDPE composites were prepared to compare their mechanical properties. It was found that breaking strains of polymerisation filled composites were higher than those for melt blended composites for a similar fibre concentration. Tensile data were then used to compare several models of short fibre polymer composites. Melt blended composites were found to have higher fibre aspect ratio than polymerisation filled composites due to the original treatment of the fibre with aqueous NaOH solution for polymerised-filled process. The higher breaking strain is attributed to factors such as better fibre dispersion and improved fibre-polymer interfacial adhesion. Results of calculations involving Berlin's model in combination with that of Rosen for critical aspect ratio were found to give reasonable prediction of tensile properties. In addition, it was concluded that fibre aspect ratio in composites is strongly related to the processing technique employed. 59 refs.
