Results in first series which NBR/ rNL-G compounds particularly fine size up to 20 phr loading of rNL-G, showed overall improvement in cure characteristic, tensile, physical and thermal properties compared to coarser size and other rNL-G loading. Meanwhile, in second series, the incorporation of sawdust short fiber (SD) as natural filler at different loading was studied with optimum rNL-G loading filled NBR from the first series. Results indicated that, the addition of SD loading at 5 phr increased the adhesion between NBR matrix, which led to improve the cure characteristics such as lower cure time and increase the stiffness and rigidity such as modulus and hardness. At third series, the addition of 6 phr of trans-polyoctylene rubber (TOR) as a compatibilizer has increased the crosslinking density and enhanced the incorporation of NBR/ rNL-G compounds, therefore improving the compatibility of NBR/ rNL-G compounds. Most of cure characteristics, tensile, physical and thermal properties of compatibilised NBR/ rNL-G compounds, particularly 6 phr TOR showed better overall properties than uncompatibilised NBR/ rNL-G compounds. The combination of all material referring from optimum loading of 1st series at 20 phr rNL-G/ fine size, 2nd series at 5 phr SD and 3rd series at 6 phr TOR. The NBR/ rNL-G /SD/TOR compound exhibited the most improvement properties particularly the thermal stability, tensile and physical properties. The tensile fracture surface of all series were supported by scanning electron microscopy (SEM) observation proved the behavior of optimum strength of each compound respectively. 2015 2023-03-23T02:48:14Z 2023-03-23T02:48:14Z Thesis http://dspace.unimap.edu.my:80/xmlui/handle/123456789/78192 en Universiti Malaysia Perlis (UniMAP) Universiti Malaysia Perlis (UniMAP) School of Materials Engineering |
