Abstract

The increasingly widespread use of structural steel in everyday life, despite its tendency to undergo corrosion, results in financial losses and poses safety risks if damage occurs. This study aims to analyze the effects of nitrocarburizing on the hardness, corrosion rate, microstructure, and composition of low-carbon materials SS400 and ASTM A36. The research method used is experimental. Data analysis techniques were obtained by comparing the results of each test. The nitrocarburizing test results showed differences in hardness values and corrosion rates for SS400 and ASTM A36. The SS400 test results at 350°C were 221.04 VHN and 0.26993 mpy, at 400°C were 278.85 VHN and 0.30959 mpy, and at 450°C were 440.39 VHN and 1.4548 mpy. The ASTM A36 test results at 350°C were 377.43 VHN and 0.43071 mpy, at 400°C were 399.58 VHN and 0.085371 mpy, and at 450°C were 230.83 VHN and 1.4336 mpy.

Abstract

Natural fiber composites are increasingly being developed to substitute less environmentally friendly materials such as metal and fiberglass. Petung bamboo has the potential to be a substitute for glass fiber in polymer composite reinforcement because it has good fiber quality. This research aims to determine the effect of random fiber arrangement with variations in fiber length on mechanical strength. The composite was made using the hand lay-up method with fiber length variations of 5 mm, 10 mm, 15 mm, and 20 mm. The volume fraction of petung bamboo fiber is 30% soaked in 5% NaOH for 2 hours. The research results show that specimen C has the highest tensile strength and elastic modulus values ​​of 1.25 Kgf/mm^2 and 1.93 Kgf/mm^2. In contrast, specimen A has the lowest tensile strength and elastic modulus values ​​of 0.76 Kgf/mm ^2 and 1.14 Kgf/mm^2. The rich, void, and fiber pull-out matrix causes the mechanical strength of the composite to be less than optimal. The effect of adding petung bamboo fiber in the composite can increase the mechanical strength as the fiber length increases.

Abstract

The use of lightweight plastic materials is widely applied in the manufacturing of car dashboards. Lightweight plastics or polymers, such as ABS plastic, are not strong enough or can easily crack when impacted. Banana pseudostem fibers have good mechanical properties and are a potential reinforcement for composites. This study aims to analyze the tensile strength of unsaturated polyester-banana pseudostem fiber composites produced through the hand lay-up method at three different angles: 0°/90°, 15°/105°, and 30°/120°. The tensile testing refers to ASTM D638 standards. The results of the tensile tests show that the 0°/90° weaving angle variation had the highest tensile strength value, which was 372.07 MPa. The 30°/120° fiber orientation variation had the lowest tensile strength value at 198.12 MPa. The fractures from the tensile tests were observed through macro photos to understand the failure mode. The macro photo observations showed that all specimens experienced fiber pull-out.

Abstract

Permasalahan pada sektor transportasi seperti kecelakaan lalu lintas menjadi perhatian penting, salah satunya disebabkan oleh kondisi kendaraan yang kurang optimal dalam menyerap energi benturan. Oleh karena itu, dibutuhkan material alternatif yang ringan namun memiliki kekuatan mekanik tinggi, salah satunya yaitu komposit serat karbon untuk aplikasi bodi kendaraan. Penelitian ini bertujuan untuk menganalisis pengaruh variasi lama waktu curing terhadap kekuatan tarik dan impak material komposit berbahan serat karbon. Material komposit menggunakan serat karbon 3K Twill 220 gsm dan resin epoksi dengan perbandingan resin : hardener (2:1). Proses pembuatan komposit dilakukan dengan kombinasi metode Hand Lay-Up dan Vacuum Bagging, serta variasi lama waktu curing 30 menit, 45 menit, dan 60 menit pada suhu 100°C. Pengujian kekuatan tarik mengacu pada standar ASTM D3039 dan pengujian impak Charpy mengacu pada ASTM E23. Hasil pengujian menunjukkan bahwa nilai tegangan tarik tertinggi diperoleh pada spesimen dengan waktu curing 60 menit sebesar 190,86 MPa. Pada uji impak, energi serap dan ketangguhan impak tertinggi diperoleh pada waktu curing 30 menit dengan nilai masing-masing 1,339 J dan 0,253 J/mm². Dengan demikian, waktu curing 60 menit memberikan kekuatan tarik maksimal, sementara waktu curing 30 menit unggul dalam ketangguhan impak. Penentuan lama waktu curing optimal perlu disesuaikan dengan kebutuhan karakteristik yang lebih spesifik. Kata Kunci: Komposit serat karbon, curing, hand lay-up, vacuum bagging.ABSTRACTIssues in the transportation sector, such as traffic accidents, are partly caused by vehicles' poor ability to absorb impact energy. This highlights the need for lightweight materials with high mechanical strength, such as carbon fiber composites, for energy-efficient vehicle body applications. This study investigates the effect of curing time variations on the tensile and impact strength of carbon fiber composites made from 3K Twill 220 gsm carbon fiber and epoxy resin (resin:hardener ratio of 2:1). The composites were fabricated using Hand Lay-Up and Vacuum Bagging methods, with curing times of 30, 45, and 60 minutes at 100°C. Tensile tests followed ASTM D3039 and impact tests followed ASTM E23. The highest tensile strength 190,86 MPa was achieved at 60 minutes, For the impact test, the highest absorbed energy and impact toughness were achieved at 30 minutes of curing, with values of 1.339 J and 0.253 J/mm². Therefore, a curing time of 60 minutes provides maximum tensile strength, while a curing time of 30 minutes excels in impact toughness. The determination of the optimal curing time needs to be adjusted to the specific characteristic requirements.Keywords: carbon fiber composite, curing, hand lay-up, vacuum bagging

Abstract

Aplikasi terpal PE (polyethylene) sering melibatkan interaksi langsung dengan lingkungan luar dan beban. Hal ini dapat   mengakibatkan perubahan pada sifat-sifatnya sehingga mempengaruhi umur pemakaian. Sejauh ini, penurunan sifat-sifat mekanis material polyethylene telah diamati pada berbagai penelitian, namun belum ada yang secara khusus berfokus pada struktur anyaman seperti terpal. Artikel ini menginvestigasi penurunan sifat mekanis yang disebabkan oleh kedua faktor di atas pada bahan terpal. Uji tarik dan uji jebol dilakukan terhadap spesimen bahan terpal yang telah dipapar cuaca selama 1, 2, dan 3 bulan, dengan dan tanpa beban kontinu. Ditemukan penurunan sifat-sifat mekanis secara bertahap seiring dengan lama paparan. Perbandingan antara spesimen terpal baru dan yang telah diberi perlakuan paparan selama 3 bulan menunjukkan penurunan kekuatan tarik dan kemuluran sebesar 56% dan 67%. Pada semua variasi waktu paparan, spesimen dengan beban kontinu mengalami penurunan sifat yang lebih besar daripada spesimen tanpa beban. Baik degradasi bahan polyethylene maupun perubahan struktur anyaman disinyalir berpengaruh terhadap perubahan karakteristik mekanis pada spesimen dengan beban kontinu.

Abstract

This study discusses the design and development of a Jominy Hardenability Test apparatus based on the ASTM A255 standard, which is used to determine the hardenability of metallic materials, particularly steel. The purpose of this research is to produce a Jominy testing device that meets standard specifications, perform structural analysis using CAD Software, and evaluate the functional performance of the manufactured tool. The research method consists of several stages, including 3D design using CAD Software, structural analysis simulation with the Finite Element Analysis (FEA) method covering von Mises stress, displacement, and safety factor, followed by the manufacturing process according to the design results. The simulation results show a maximum stress of 2.039 × 106 N/m², a maximum displacement of 5.8 × 10⁻¹ mm, and a safety factor value of 2.6, indicating that the design is structurally safe for production. The manufacturing process uses galvanized as the frame, body material and includes an additional cooling fan to maintain water temperature stability during the quenching process. The functional test results show that the tool can perform quenching effectively, producing a maximum hardness value of 370 VHN and a minimum value of 280 VHN on the steel specimen. This research is expected to contribute as a reference for the development of economical, efficient, and standard ASTM A255 compliant Jominy testing equipment for researh and development.

Abstract

AISI 1045 steel is widely used in machine components due to its high strength and good wear resistance, but its mechanical properties can still be optimized through heat treatment. This research aims to determine the effect of cooling media and variations in tempering temperature on the characteristics of AISI 1045 steel. The problem studied is how the quenching temperature (800°C and 850°C) and the type of cooling media (25% salt water and biodiesel) influence the tensile strength, hardness, and microstructure of the steel. The research method was carried out experimentally with quenching and tempering heat treatment at a temperature of 550°C for 60 minutes, followed by tensile tests, Vickers hardness tests, and microstructure observations. The research results showed that the highest hardness value was found in the 850°C quenched salt water specimen, which was 576.10 kgf/μm, while the highest tensile strength in the tempered 850°C salt water specimen was 1047.53 MPa, and the highest strain in the tempered 850°C biodiesel specimen was 29.17%. The formed microstructure shows the presence of tempered martensite and fine carbide precipitation, which increases the material’s ductility. In conclusion, the combination of a quenching temperature of 850°C with salt water media.
