Abstract

Composites are made of multiple materials that are combined to create new materials with better properties. The purpose of this study is to determine the effects of SiC and Cu weight fractions on hardness, tensile strength, microstructure and scanning electron microscopy (SEM) of Al 6061 composites. The manufacturing method used for creating composites in this study was stir-casting. Each composite component and its functions are as follows: aluminum 6061 as the matrix, silicon carbide (SiC) as a reinforcement, and copper (Cu) functions to improve the characteristics of the composite. Variations were made by weight composition of SiC (1%, 3%, and 5%) and Cu (5% and 8%). Observations were carried out on their hardness, tensile strength, and microstructure; each of which using Rockwell hardness test B (ASTM E 18 standard), a multipurpose tensile testing machine, and SEM, respectively. The results of this study indicate that the addition of SiC and Cu affects the aluminum 6061 characteristics. The best result of the hardness test was shown at Al6061 + 5% SiC + 8% Cu (109.37 HRB). The best tensile strength (UTS) test result was shown at Al6061 + 5% SiC + 8% Cu (211.8 MPa) with elongation number of 2.8%. There has been a significant reduction in grain size under micro observations that occurred very well but was still relatively not uniform. The result of several SEM observation phases formed by the combination of Al6061 and the addition of 5% SiC + 5% Cu and 8% Cu showed an observation phase of AlZnMgCu, α (Al) + AlZnMgCu, Al2Cu, and Al2CuMg.

Abstract

3D printing machines are used to print products that support sports activities, such as shin guards. During sports, shin guards are protective equipment to prevent injury to the lower legs. Filaments that are suitable for making shin guards are thermoplastic polyurethane (TPU) and polyethylene terephthalate (PETG) because they have impact resistance properties needed to protect the feet during sports. The variation is the level parameter layer height, nozzle temperature, printing speed, and bed temperature. Next, an impact test will be carried out to determine the optimal parameter variation on the 3D printing machine, which is expected to be a reference for printing quality products. This study uses a 3D printer, Ender v3, to print specimens and shin guard products. The material used is TPU+PETG filament. The Taguchi method with the orthogonal matrix L9(3)4 was repeated thrice for each experiment. After that, an analysis of variance was carried out. Parameter variations used in the study were layer height (0.1 mm, 0.2 mm, 0.3 mm), nozzle temperature (220℃, 225℃, 230℃), printing speed (45mm/s, 45mm/s, 50mm/s) and bed temperature. (70℃, 75℃, 80℃). In this study, Charpy impact testing will be carried out. The combination of factors that can produce an optimal impact test is layer height level 2 (0.2 mm), nozzle temperature level 1 (220℃), printing speed level 3 (50 mm/s) and bed temperature level 2 (75℃) with an impact strength value the highest was 27.20 and the lowest was 11.07. The combination of factors that have the most significant effect on the impact test strength values is layer height 63.97%, nozzle temperature 6.19%, printing speed 2.07% and bed temperature 4.74%.
