Abstract

Natural fiber reinforced composites have advantages as composite reinforcement, namely having a relatively light density and strength and stiffness are also quite high. In this study the authors made specimens using natural fibers in the form of vetiver fiber (vetiveria zizanioides) as composite reinforcement and added tile powder as filler, tile powder has good compounds to strengthen the resulting composite. The purpose of this study was to test the combustion resistance of vetiver fiber reinforced composites and roof tile powder with polyester resin as the matrix. This composite is made by hand lay up technique with variation of volume fraction of vetiver fiber 0%, 5%, 10%, 15%, 20%, roof tile powder 20%, 15%, 10%, 5%, 0%, 80% polyester resin with random fiber orientation. Combustion resistance testing was conducted according to ASTM D-635 standard. The results of this study indicate that composites with volume fractions (20%, 0%, 80%) make this composite flammable, namely with an average Time Of Burning value of 26.52 seconds. While composites with volume fractions (0%, 20%, 80%) are composites that have the most fire-resistant properties with an average Rate Of Burning value of 18.723 mm/min. Composites with a lot of vetiver fiber composition have a faster ignition process, while composites that are only given tile powder filler have a longer ignition process. Meanwhile, the more vetiver fiber composition, the faster the process of ignition.

Abstract

Natural fiber reinforced composite materials are increasingly being developed as an alternative to metal due to their lightweight, strong, and environmentally friendly properties. This study used pineapple leaf fiber and shell powder with an epoxy matrix to determine the optimal composition to improve the tensile properties of the composite. The purpose of this study was to determine how much fiber influences the tensile strength of pineapple leaf fiber and shell powder with an epoxy resin matrix. Specimens were made using the hand lay-up method and alkalization treatment, with a fixed composition of 60% epoxy, while the content of pineapple leaf fiber and shell powder varied from 10%; 15%; 20%; 25%; 30%. Tensile tests were carried out in accordance with ASTM D638. The results showed that the composition of 60% epoxy, 25% pineapple leaf fiber, and 15% shell powder produced the highest tensile strength of 20.80 MPa and the highest elastic modulus of 2029.4 MPa, while the highest strain value of 0.0228 was obtained in the composition of 60% epoxy, 15% pineapple leaf fiber, and 25% shell powder. In general, pineapple leaf fiber contributes to increasing tensile strength, while shell powder increases material stiffness through a more even stress distribution.

Abstract

This study investigates the effect of varying weight fractions of sugarcane fiber and fiberglass on the mechanical properties of polyester resin-based composite, with a focus on improving tensile strength. Sugarcane fiber, a lignocellulosic natural reinforcement with a length of 3 cm, was used alongside fiberglass as a synthetic reinforcement to evaluate the performance of hybrid composites. Specimens were fabricated using the hand lay-up method with five combinations of sugarcane fiber (0–10%) and fiberglass (0–10%), while the polymer resin and catalyst comprised 90% of the total composite weight. Tensile testing was conducted according to ASTM D638-01 using a Universal Testing Machine. The evaluated parameters include maximum tensile stress, strain, and elastic modulus. Experimental results showed the highest tensile strength of 88,186 MPa at 0% sugarcane fiber and 10% fiberglass, and the lowest value of 27,154 MPa at 10% sugarcane fiber with no fiberglass. The maximum strain observed was 0.0050 mm/mm, and the minimum was 0.0012 mm/mm. The highest elastic modulus was 71,287 MPa, while the lowest was 5,384 MPa. These results confirm that an optimal combination of natural and synthetic fibers significantly enhances the mechanical performance of the composite. This research highlights the potential of sugarcane fiber as a sustainable reinforcement alternative in the development of environmentally friendly composite materials.

Abstract

Pemanfaatan serat alam dalam pengembangan material komposit terus mengalami perkembangan signifikan sebagai alternatif pengganti serat sintetis. Serat kulit kayu waru (Hibiscus tiliaceus) merupakan salah satu serat alam yang keberadaannya melimpah di Indonesia, namun pemanfaatannya masih terbatas pada industri kerajinan tangan dan pembuatan tali. Penelitian ini bertujuan untuk menganalisis kontribusi serat kulit kayu waru dan fiberglass terhadap sifat mekanik material komposit, khususnya kekuatan tarik. Metode penelitian menggunakan variasi fraksi volume serat kulit kayu waru (0%–20%) dan fiberglass (20%–0%) dengan komposisi matriks resin poliester konstan sebesar 80%. Spesimen uji dibuat menggunakan metode hand lay-up dan diuji mengikuti standar ASTM D 638-01. Hasil pengujian menunjukkan bahwa kekuatan tarik tertinggi diperoleh pada variasi A (20% fiberglass, 0% serat waru) sebesar 135,25 MPa, sedangkan kekuatan tarik terendah ditemukan pada variasi E (0% fiberglass, 20% serat waru) sebesar 30,03 MPa. Meskipun kekuatan tarik serat kulit kayu waru belum setara dengan fiberglass, hasil penelitian menunjukkan bahwa serat kulit kayu waru memiliki potensi yang baik sebagai material penguat alternatif dalam aplikasi komposit dengan beban rendah hingga sedang, sekaligus mendukung pengembangan material ramah lingkungan dan berkelanjutan.

Abstract

The use of natural fibers as alternative materials continues to attract attention because they are environmentally friendly, economical, and readily available. Elephant grass (Pennisetum purpureum) is one natural fiber with potential for such applications. This study investigated the effect of different immersion times in potassium hydroxide (KOH) solution on the tensile properties of single elephant grass fibers. We used an experimental method with 10% KOH alkaline treatment and immersion times of 0, 2, 4, 6, and 8 hours. Tensile testing was conducted using a Universal Testing Machine (UTM) to determine tensile stress, strain, and elastic modulus. The results showed that immersion time affected the mechanical properties of the fibers. The highest tensile stress, strain, and elastic modulus were obtained after 8 hours of immersion, reaching 8868.11 MPa, 14%, and 63523 MPa, respectively the alkaline treatment removed impurities from the fiber surface, improving its ability to withstand tensile loading. Therefore, 8 hours of immersion in 10% KOH provided the optimum result and demonstrated the potential of elephant grass fiber as reinforcement for environmentally friendly composites.

Abstract

This study aims to analyze the effect of variations in luffa (Luffa acutangula) fiber length on the tensile properties of Polyester resin matrix composites. The composites were made by hand lay-up using a volume fraction of 90% resin and 10% fiber, with fiber lengths of 5 mm, 7 mm, 9 mm, and 11 mm, and tested using a UTM according to ASTM D638. The results showed fluctuating mechanical properties, with the highest tensile strength and maximum stress at 9 mm (0.816 kN and 20.31 MPa) and the lowest at 7 mm (0.681 kN and 17.27 MPa). The highest strain occurred at 9 mm (0.019) and the lowest at 5 mm and 7 mm (0.015), while the highest modulus of elasticity was at 5 mm (1387.610 MPa) and the lowest at 11 mm (970.5158 MPa). Overall, a fiber length of 9 mm is the optimum condition because it produces the best balance between strength and deformation.

Abstract

This study aims to analyze the structural performance of a redesigned adjustable spreader for Electric Train (KRL) carbodies under a maximum static operational load of 40 tons. The research employs the Finite Element Analysis (FEA) method using ANSYS Workbench 2024 R2 to evaluate three alternative cross-sectional profiles, namely hollow square, hollow rectangular, and hollow round, fabricated from SS400 steel. The analysis focuses on Von Mises stress, total deformation, and safety factor to determine the most reliable and efficient design configuration. The simulation results at the maximum 4000 mm span indicate that all redesigned profiles are structurally safe, with maximum Von Mises stresses ranging from 107 to 110 MPa, which remains well below the material yield strength of 205–245 MPa. Among the evaluated variations, the hollow square profile demonstrates the most optimal mechanical performance, exhibiting the lowest total deformation of 0.076663 mm and the highest safety factor of 3.011. Furthermore, this profile offers superior fabrication efficiency due to its flat surfaces, effectively resolving vulnerabilities and rigidity issues in the existing design.
