| Summary: | This research focusing on mechanical properties of rubber toughened polyester filled
carbon black (RPCB) reinforced with untreated kenaf (RPCBUK) and treated kenaf (RPCBTK).
The samples were fabricated via compression moulding technique in which 3 % of LNR was added
as toughening agent in this composite. Percentages of carbon black (CB) is 4 % and kenaf used vary
from 5,10,15,20 and 25wt %. The mechanical properties were evaluated by impact and fracture
toughness testing. The result for each test was discussed to determine the most optimum loading of
kenaf fibre used to produce the best properties of composite. Untreated hybrid composite showed
improvement on impact strength as compared to RPCB composite. RPCBTK with 25% of kenaf
and RPCBUK with 5% of kenaf loading give the highest impact strength among the hybrid
composites, approaching the strength of neat polyester. Same trend shows by fracture toughness
testing. The microstructures of the composites’ fracture surface images from scanning electron
microscope (SEM) prove the mechanical properties of the hybrid composites. |
