【 摘 要 】

Kenaf fibre is one of the strongest natural fibres in the world today. For that purpose, the purpose of this study is to create a new composite of Kenaf fibres combined with marble waste powder. The incorporation of marble powders and Kenaf fibres using a matrix of a polyester resin type has never been done. Thus, this study aims to create and test various composite material composites (mixture of matrix, marble powder and Kenaf fibre) which will produce different mechanical properties and obtain good tensile strength in test specimens with several composition variations. Preparation of test specimens was carried out with 4 (four) compositions of matrix mix and marble powder that is 50:50, 60:40, 70:30 and 80:20 with the weight of Kenaf fibre fixed 2 gram. The largest tensile test value is 63,407 MPa, obtained from 80:20 composition with the largest E value 3.03 GPa. The largest compression test value is 33.49, obtained from the composition of 60:40 with the largest E value of 2.35 GPa. The largest bending test value is 19.80 MPa, obtained from the composition of 80:20 with the largest E value of 36.55 GPa. From the research results of the tensile test, compression test, and bending test which possess good value is between composition ratio 60:40 and 70:30.
