Abstract

Due to high interest in high quality but low cost material, lots of researches have been done by the researcher and engineers. Together with the increasing usage of composite material from the mixture of natural materials. This technical report will proposed a research for a vibration insulator application. Coconut fiber and natural rubber is the material selected materials for this research as it offer lots of advantage which it has high quality as well as easy to found especially in Malaysia. This mixture of coconut fiber and natural rubber is mixed together then it goes to cold press process in a mold. The mixture is fabricated into composite with different composition of natural rubber of 5 wt.%, 10 wt.%, 15 wt.%, 20 wt.%, 25 wt.%, 30 wt.%, 35 wt.%, 40 wt.%, 45 wt.%, 50 wt.%, 55 wt.% and 60 wt.% of latex respectively. Mold of ten millimeters in thickness is prepared as the mold of the specimen preparation. A specimen of 100 percent coconut fiber also fabricated as comparison to the specimens with natural rubber for its mechanical properties determination. From the results obtained in the vibration testing, the fiber composite with 35 wt.% of latex is the best specimen in the vibration insulator application. This is because the vibration coefficient that produced in the vibration testing is the higher compared to the others specimen with 1.344 x 10-2. The different percentage between the specimen with 35 wt.% of latex and the actual material also is higher that is 313.26 %. While the value of Young’s Modulus for the tensile test and compression test are 0.033473 MPa and 0.07959 Mpa respectively. This data show that the composite with 35 wt.% of natural latex is suitable in the vibration insulator application.
