Abstract

A composite is one of the materials that is a mixture of two or more materials to form a third, more useful material. In this study, researchers chose bamboo fiber and iron sand as reinforcement for composite materials because the selection of bamboo fiber as a research material took into account the potential of bamboo fiber in Indonesia which is abundant and has not been utilized properly. The purpose of making bamboo fibrous composite materials aims to find a material that is lighter stronger and more elastic, can be developed into other products such as the manufacture of drone frames, aircraft bodies, brake pads. The method used is an experiment with making specimens using the hand lay up method and testing using impact testing and micro photo testing. Impact testing is used to determine the properties and characteristics of the material in the form of strength, hardness, and ductility of the material while for micro photos it is used to determine the bond of the material composition with the best impact test. The test standards used are ASTM D6110-10 with random fiber arrangement and ASTM D6110-04 with the arrangement of woven fibers, with variations in volume composition of bamboo fiber and iron sand particles. In the D6110-10 specimens, the best specimens were found in the variation with the most bamboo fibers, namely 35S10 P with an impact energy of 4.27 J and an impact price of 0.04 J / mm2, while the lowest variation was found in the most iron sand, namely 35P10S with an impact energy value of 2.26 J and an impact price of 0.02 J / mm2. In the D6110-04 specimen also showed the same characteristics as the ASTM D6110-10 specimen, the 30S30P variation or the composition of the most bamboo fibers had an impact energy value of 4.09 J while in the 10S10P variation it was only 1.47 J. Thus the more bamboo fibers will make the impact strength of the specimen higher.

Abstract

Aluminum alloy in the aerospace field has been widely used in the manufacture of skins from aircraft. The use of aluminum alloy has the advantages of relatively high mechanical strength and resistance to corrosion. In order to raise the strength of the material and the physical appearance of aluminum can use the electroplating method. Electroplating is a method used to coat metals with other types of metals, the coating process uses the help of electric current. The electric current used will trigger the release of metal ions at the anode to be further attached to the cathode. In this study, an electroplating process was carried out on 2024 aluminum alloy specimens with nickel coating. The variations in this study used differences in electric current voltages of 25 V, 35 V, and 45 V. Then to find out the differences from the variations that have been used, tensile tests and hardness tests were carried out. From the results of the tensile test, it shows that the higher the voltage of the electric current used, it will increase the tensile strength, but the yield strength will decrease. The highest tensile strength is found in the voltage variation of 45 V with a value of 452.53 MPa. Then on the hardness test shows that the higher the voltage of the electric current will reduce the hardness value. The highest hardness value is found at a voltage of 25 V with a value of 963.594.

Abstract

Aluminum alloy 7075 series is one that is widely used in the aviation industry. More than 73% of aircraft components are aluminum alloy 7075 series because the properties of this aluminum can still be improved by giving it a treatment. The purpose of this study was to determine the effect of differences in nickel coating types on 7075-T6 aluminum plates on the level of hardness.aluminum plates with a length of 2 cm and a width of 2 cm as many as each variation of 4 specimens. temperature variations of 30 °C, 35 °C, 40 °C, 45 °C and time of 5, 10, 15, 20 minutes. The hardness value is obtained using a brinell test device, using a diamond pyramid indenter used for vickers hardness tests. The test object is pressed for 5 seconds with a load of 31.25 kgf and a magnification of 5 times. Hardness testing is carried out at 1 point of the surface of the specimen. Based on the results of research and calculations and discussions about the effect of temperature variations on the strength of mechanics by the electroplating method, it is known that the difference in time and temperature variations on the hardness of aluminum 7075-T6 shows an influence on the value of significant hardness. And the optimal variation value was obtained, namely the highest hardness value at a temperature of 45 ° C at a time of 5 minutes, namely 483.63 kgf / mm² and the lowest average hardness value at a temperature of 30 ° C at a 15-minute immersion time of 292.33 kgf / mm².

Abstract

The purpose of this study was to determine the bending strength of carbon fiber composite materials with lycal epoxy resin on the Skywalker 1900 UAV. Composites will be made for test specimens with carbon fiber combined with lycal resin using vacuum infusion printing and vacuum bagging methods. From these two methods a sample of specimens will be made for testing using a bending test using the three point bending method to determine the bending strength value of the fuselage material. As for another test, namely microphotos, the process of observing this microstructure can find out how the shape, size, and distribution of second phase particles have an important role in knowing the properties of the material itself. The results of the test specimens were compared between vacuum infusion printing and vacuum bagging and then the best value was sought between the two methods. The results were obtained after testing where the two methods of printing and micro-photos obtained the best results in vacuum bagging. In the vacuum bagging process, the highest value was found in specimen b2 with a bending stress value of 1201.90Mpa and the lowest yield was found in specimen i1 with a bending stress value of 1017.74Mpa. Then the micro photo test can be seen in the vacuum bagging printing process, the penetration of the resin in bagging to the fiber is better.

Abstract

This study aims to know the cost of designing maintenance using the Reliability Centered Maintenance method. Engine and fuel control, is a fuel engine system and fuel control system; in charge of distributing and measuring fuel from the fuel storage tank, to the combustion chamber. Gas turbine or component area (Combustor), functions as a distributor of fuel used in aircraft systems and plays a role in carrying out its operation (Boeing 737-400 Aircraft Maintenance Manual). Reliability is the possibility of a component or system to be able to operate and/or carry out its functions. The function has been assigned to certain operating conditions and in a certain environment for a predetermined period of time. Thus, reliability is the probability that it will not fail or be able to perform its function for a period of time (t) or more. In the analysis of preventive maintenance financing, which is carried out when the reliability value reaches 70%, 60% and 50%, respectively, it is obtained for each component.

Abstract

Penggunaan material komposit dalam industri penerbangan semakin meningkat, menggantikan baja dan aluminium. Metode Vacuum Resin Infusion yang lebih efisien dibandingkan metode tradisional seperti Hand Lay-Up telah dikembangkan untuk meningkatkan kualitas dan menurunkan biaya produksi komposit yang digunakan pada struktur pesawat, UAV, dan drone. Penelitian ini menggunakan metode eksperimental dengan dua teknik pembuatan komposit: Vacuum Infusion dan Hand Lay-Up. Spesimen dibuat menggunakan variasi pipa spiral pada metode Vacuum Infusion. Pengujian meliputi evaluasi void menggunakan foto mikroskop dan pengukuran berat jenis material untuk membandingkan kualitas komposit yang dihasilkan oleh kedua metode tersebut. Mengetahui perbedaan kualitas material komposit yang dihasilkan oleh metode Vacuum Infusion dan Hand Lay-Up berdasarkan void dan berat jenisnya. Metode Vacuum Infusion dengan spiral out menunjukkan jumlah void paling sedikit dan nilai berat jenis tertinggi sebesar 0.00157 gram/mm³ dibandingkan dengan metode lain, menunjukkan bahwa metode ini menghasilkan komposit dengan kualitas dan kerapatan yang lebih baik, sehingga lebih unggul dalam hal kekuatan dan ketahanan material.
