| dc.description.abstract | Development of composite technology began to grow rapidly, composites are now many who use natural fibers as a substitute for synthetic fibers. The composite function in a variety of components, among others, used for automotive, electric cars, aircraft, ships and sports equipment. Preparation of composites containing cane powder and portland cement matrix was carried out with the variables used: sugae cane powder size 0.18 mm, 0.25 mm and 0.42 mm. Steel powder sizes: 1.2 mm, 1.8 mm and 2.4 mm. The observed parameters were tensile strength and impact strength of composite materials. From this research, the optimum tensile strength value was found on the size of 0.18 mm cane powder and 1.2 mm steel powder size with a tensile strength value of 0.38 N/mm2 . The optimum impact strength value occurred on the size of 0.18 mm cane powder and 2.4 mm steel powder size with impact strength value of 1.44 J/mm2 . From the results of macro observation for the impact test results the type of fracture formed is a brittle fracture. | en_US |
