Abstract

Kampas rem merupakan komponen yang mempunyai fungsi memperlambat atau menghentikan laju kendaraan. Perkembangan teknologi material telah menghasilkan jenis material baru yaitu komposit merupakan campuran dari 2 bahan atau lebih yang dirancang untuk mencapai kombinasi material terbaik. Penelitian ini yaitu membuat kampas rem dengan menggunakan pasir besi, resin dan juga serat bambu dengan menggunakan variasi volume material. Kemudian di uji dengan menggunakan uji impact untuk mendapatkan hasil material yang terbaik untuk di jadikan kampas rem yang layak. Hasil pengujian spesimen terbaik setiap variasi yaitu spesimen B dengan variasi 10 % serat, 10 % pasir dan 80 % resin menghasilkan energi impact sebesar 3.9426955 J dan menghasilkan harga impact sebesar 0.032855796 J/mm2. Untuk variasi 25 % serat, 25 % pasir dan 50 % resin spesimen terbaiknya yaitu spesimen F menghasilkan nilai energi impact sebesar 5.1717768 J dan menghasilkan harga impact sebesar 0.04420322 J/mm2. Untuk variasi 40 % serat, 40 % pasir, dan 20 % resin spesimen terbaik yaitu spesimen H memiliki energi impact sebesar 6.357648 J dan harga impact senilai 0.06357648 J/mm2.

Abstract

The use of composites as materials has developed rapidly due to the many advantages they offer compared to alternative engineering materials. In this study, the researchers used Glass Laminated Aluminium Reinforced Epoxy (GLARE) to analyze the results of bending tests on hybrid laminate composites reinforced with fiberglass and aluminum plates. The method used was vacuum bagging, and the sample was reinforced with epoxy resin combined with carbon nanotube (CNT) nanoparticles and aluminum (AL) powder. This study applied variations in resin as adhesive, surface treatments, and the addition of CNT and AL nanopowders to determine their effects on the bending strength of the composite. The results showed that specimens with surface treatment and nanoparticle additions had higher bending strength compared to those without nanoparticles or surface treatment. The highest bending stress was found in the CNT variation specimens, with an average value of 181.4158 MPa. The lowest average bending stress was observed in the plain specimens without nanoparticles and surface treatment, with a value of 151.766 MPa. Macro photo analysis after the bending test showed adhesive failure in the plain variation (no resin adhered to the aluminum surface), and cohesive failure in the CNT variation (resin adhered to the treated aluminum surface). These findings indicate that the addition of nanoparticles improves bending strength. This research plays an important role in understanding the influence of nano adhesives and nanoparticles on the bending strength of hybrid laminate composites.
