This paper presents the performance of short carbon fibre (CF) reinforced and filled with sawdust (SD) hybrid epoxy composites were evaluated. The results showed that hybridisation of carbon fibre and sawdust was in similarity to EP/CF hybrid composites. Effect of fibre orientation in matrix and the analysis and fracture surface was undertaken. The mechanical properties of injection moulded, chopped carbon fibre/sawdust/epoxy hybrid composites were investigated by considering the effect of hybridisation by these two fillers. It was observed that the tensile, flexural, and impact properties of the filled epoxy were higher than those of unfilled epoxy. The effect of filler on epoxy matrix subjected to the tensile strength and modulus was studied and compared with the rule of hybrid mixtures. The effect of filler on epoxy matrix subjected to the tensile strength and modulus was studied and compared with the rule of mixture. The actual results are marginally low as compared with the values obtained by the rule of hybrid mixtures (RoHM).

ABSTRACT. Short carbon fibre (CF) and sawdust (SD) were dispersed in to the epoxy (EP) matrix in order to manufacture polymer hybrid composites using compression moulding technique. The mechanical properties of flexural properties of hybrid, compression moulded, chopped CF/SD/epoxy composites have been investigated taking into account the effect of hybridization by these two fillers. Hybridization with small amounts of SD makes these CF composites more suitable for technical applications. The simultaneous compounding of epoxy with two fillers was done to obtain a hybrid composite. This system is expected to have considerable mechanical properties, good surface finish and low cost. It has been found that the tensile properties of filled epoxy were higher than unfilled epoxy. By incorporating up to 30% (by mass) Carbon fiber (CF) and 10% sawdust (SD) namely S 3 sample flexural strength was increased by 12.5%. Thus it is shown that the durability of CF/SD filled epoxy composites can be enhanced by hybridization with small amount of CF. The hybrid effects of the flexural strength and modulus were studied by the rule of hybrid mixture.
