Abstract

Kampas rem umumnya terbuat dari bahan asbestos, yang memiliki dampak negatif terhadap lingkungan dan performa. Bahan alternatif ramah lingkungan seperti serat eceng gondok, serbuk kayu jati, dan serabut kelapa yang belum banyak dimanfaatkan, berpotensi menggantikan asbestos. Penelitian ini bertujuan untuk mengevaluasi komposit serat eceng gondok, serbuk kayu jati, dan serabut kelapa terhadap sifat termal dan kekerasan sesuai standar kampas rem. Tiga spesimen kampas rem dibuat menggunakan matriks resin polyester 50%, yaitu, Spesimen A dengan 40% serat eceng gondok, 10% serbuk kayu jati, dan 0% serabut kelapa; Spesimen B dengan 40% serabut kelapa, 10% serbuk kayu jati, dan 0% serat eceng gondok; serta Spesimen C dengan masing-masing 20% serat eceng gondok dan serabut kelapa, serta 10% serbuk kayu jati. Pengujian dilakukan menggunakan Thermogravimetric Analysis (TGA) dan Durometer Shore D. Hasil penelitian menunjukkan bahwa pengujian ketahanan termal pada variasi komposit Spesimen A dan Spesimen B memiliki ketahanan termal masing-masing sebesar 224,6℃ dan 228,48℃, mendekati standar SAE J661 (250℃-350℃). Lalu, untuk hasil pengujian kekerasan pada variasi komposisi Spesimen A, Spesimen B, dan Spesimen C dengan nilai kekerasan masing-masing sebesar 57,8 HD (77,8 Rockwell R), 51,3 HD (71,3 Rockwell R), 53,4 HD (73,4 Rockwell R), sudah masuk kedalam standar SAE J661 (68-105 Rockwell R). ***** Brake pads are generally made from asbestos, which negatively impacts both the environment and performance. Eco-friendly alternatives, such as water hyacinth fibers, teak wood powder, and coconut coir, which are underutilized, have the potential to replace asbestos. This study aims to evaluate composites made of water hyacinth fibers, teak wood powder, and coconut coir in terms of thermal properties and hardness according to brake pad standards. Three brake pad specimens were fabricated using a polyester resin matrix (50%), namely Specimen A with 40% water hyacinth fibers, 10% teak wood powder, and 0% coconut coir; Specimen B with 40% coconut coir, 10% teak wood powder, and 0% water hyacinth fibers; and Specimen C with 20% water hyacinth fibers, 20% coconut coir, and 10% teak wood powder. The tests were conducted using Thermogravimetric Analysis (TGA) and a Shore D durometer. The research results indicate that the thermal resistance tests on the composite variations of Specimen A and Specimen B showed thermal resistance values of 224.6℃ and 228.48℃, respectively, approaching the SAE J661 standard (250℃-350℃). Meanwhile, the hardness test results on the composite variations of Specimen A, Specimen B, and Specimen C, with hardness values of 57.8 HD (77.8 Rockwell R), 51.3 HD (71.3 Rockwell R), and 53.4 HD (73.4 Rockwell R), respectively, fall within the SAE J661 standard (68-105 Rockwell R).
