Abstract

The sandwich composite used in this investigation has a bamboo open-cell foam core and a plywood skin. In this study, the density, flatwise compressive strength, flexural strength, and water absorption of sandwich composite materials will be determined. The volume proportion of fiber in the bamboo foam core was 15% in this investigation, and PVAc adhesive was employed. The open-cell foam core has a square-shaped hollow in the center and hole spacings of 30mm, 40mm, and 60mm. The tests included density testing (ASTM C271), flatwise compression testing (ASTM C365-05), flexural testing (ASTM C393), and water absorption testing (ASTM C272). According to the study's findings, compared to sandwich composites with core-opened cell foam without holes, sandwich composites with core-opened cell foam with holes have an average density, an average specific flatwise compressive strength, and an average specific bending strength that are smaller. The percentage of water absorption in the sandwich composite demonstrates the opposite. Comparing the sandwich composite with core-opened cell foam without holes (0.45 g/cm3) to the sandwich composite with core-opened cell foam with holes, the average density of the latter decreased by 6–13%. The decrease in the avarage specific flatwise compressive strength of the sandwich composite with a hollow core was 2-20% compared to the sandwich composite with an open-cell foam core without holes (41.22 MPa/cm3/gr). The average specific bending strength of the sandwich composite with the core opened cell foam with holes was reduced by 40–50% when compared to the sandwich composite with the core opened cell foam without holes (26.38 MPa/cm3/gr).

Abstract

Composite materials are materials that are widely developed and their use has been widespread in various industrial and household sectors. Epoxy composites filled with coconut shell charcoal powder have been tested for their thermal conductivity properties using the one-dimensional conduction method. The tested specimens had dimensions of 50 mm x 50 mm x 5 mm made of epoxy and coconut shell powder with a percentage of charcoal weight of 0%, 10%, 20% and 30%. The specimen is inserted into a thermal conductivity measuring instrument made of solid aluminum which is insulated around it. The heater is mounted on the aluminum as a heat source, while the other end is left open to the free air in the room. The results showed that the highest average thermal conductivity was a 30% variation of 0.5003 W/m°C, then a 20% variation of 0.3738 W/m°C, a 10% variation of 0.3487 W/m°C. and the lowest at 0% variation without using coconut shell charcoal powder at 0.1364 W/m°C.

Abstract

Rim or wheels have various types of model designs and the number of spokes. Therefore, those wheels can have a different response on each rim model when subjected to loads such as impact loads. In this simulation, impact load testing is carried out on the rim, with variations of 4 types of geometry where this geometry differs in the design of the number of spokes. By finding the Safety Factor value on each rim,  the most optimal rim design can be determined. Explicit Dynamics can solve this problem because the impact on the simulation occurs in a very short time. In this study, the design of a cast wheel type motorcycle rim with spokes number of 5, 6, 10 and 12 with a uniformly applied impact speed of 10 km/h. The rim material used was aluminum 6061 T6 and the projectile material used was aluminum alloy. The designed rim has a diameter of 35.56 cm and a width of 4.01 cm and a mass of 2415 gram. Solidworks and Ansys software based on the finite element method were used to make it easier to design cast wheel rims. By using this software, the rim can be designed so that it can be analyzed for stresses and strains that occur when simulating impact loads on the rim plane. The simulation results show that rims with spoke 10 and 12 are categorized as safe because they have a lower average stress value than rims 5 and 6 and have a Safety Factor value above 1. In other words, rims with 10 and 12 number of spokes are the optimal design in terms of cost and strength.

Abstract

Corrosion happens differently for each point of hull plate which caused of corrosion rate differences. So that is very important to measure it for each point, which is calculated using Weight Gain Loss Method. The measurement of plate thickness that used is Ultrasonic Test Method conducted by PT BKI. To determine the condition of ship protection, then the coating and sacrificial anode system is evaluated by testing the composition and current and voltage of anode as well. Furthermore, the number and position of anode is also analyzed. So that the re-design of cathode protection is needed by referring to the PT BKI’s standards. Then the prediction of corrosion rate is calculated by using the design of cathode protection. The largest corrosion rates are in the amidships and portside for each plate lane, they are on the keel plate point K3 is 0.37 mm/years, pedestal plate point A4 is 1.05 mm/years, bilge plate point B4 is 0.62 mm/years and side plate point C5 is 0.39 mm/years. But the number of installed anode is 31 anodes with an irregular position. So in this study, done the redesign system of cathode protection based on regulations issued by PT BKI, with the result of the number of the anode is 56 units. Using the design, then carried a prediction by the result is lower, that on the keel plate is 0.073 mm/years, pedestal plate is 0.021 mm/years, bilge plate is 0.013 mm/years and the side plate is 0.014 mm/years.

Abstract

Adhesive joints are widely used in automotive industry and shipping industry. Efforts to increase the strength of the connection are still underway. This study aims to determine the effect of the amount of indentation on shear strength on low carbon steel joints and the failure mode when the number of indents is different. The connection was made of low carbon steel with epoxy adhesive as adhesive and adhesive thickness of 0.3 mm. The number of indents varied; with and without indentations 4, 9, 16, and 25 respectively. The indentation process was made by using pillar drilling with 1.5 mm diameter of drill bit. From the results, the specimen without indentation had highest shear strength was about 22 MPa. Connection strength tended to decrease with increasing indentation. By finite element modeling, the distribution of shear stress tended to be uniform without indentation, and the stress at the end of the connection for indented connections was higher than without indentation.
