Abstract

Komposit merupakan material yang tersusun atas campuran antara dua atau lebih material yang berbeda dengan masing-masing sifat kimia dan sifat fisikanya sehingga diperoleh sifat material yang lebih baik dari material penyusunnya. Dalam proses pembuatannya terdapat beberapa metode yang digunakan, diantaranya ialah metode hand lay-up yang menjadi metode paling sederhana dan metode vacuum bag yang menjadi metode penyempurnaan dari metode hand lay-up. Secara umum dalam proses pengerjaannya kedua metode tersebut tidak berbeda jauh, hanya saja pada metode vacuum bag dilakukan proses penyedotan menggunakan alat vakum yang bertujuan untuk menghilangkan resin yang berlebih dan udara yang terperangkap pada laminasi sehingga didapat komposit dengan sifat material yang lebih baik dari komposit hasil metode hand lay-up. Sehingga objek penelitian ini adalah melakukan pengujian material terhadap material komposit sandwich hasil dari metode hand lay-up dan vacuum bag dengan proses uji Tarik untuk mengetahui perbedaan sifat materialnya. Pengujian ini dilakukan terhadap 5 spesimen dengan dimensi yang mengacu pada standarisasi ASTM D3039 dari masing-masing metode tersebut. Dari proses pengujian material yang dilakukan dengan proses uji Tarik, diperoleh nilai dari parameter seperti maximal force, tensile strength, dan young’s/elastic modulus. Hasil uji Tarik terhadap specimen hasil kedua metode tersebut diketahui bahwa specimen hasil metode vacuum bag memiliki sifat material yang lebih baik dengan nilai rata-rata maximal force 1075.490 N, rata-rata tensile strength 7.507 MPa, dan rata-rata young’s / elastic modulus 463.810 MPa.

Abstract

This research contains about how much the increase in the strength of the coconut fiber composite material as a result of the press hand lay-up method with post-curing treatment on the variable duration of heat curing. With a duration of 60, 120, 180 minutes, heat curing will find out which variation has the best effectiveness, considering several factors to increase the strength of composite materials, one of which is heat curing treatment can make coconut fiber composites have higher tensile strength values and are able to utilizing coconut fiber waste which is more useful than usual as an embodiment of 3R (reuse, recycle, reduce.) through methods commonly used for composite manufacture in general and focusing on the percentage increase in post-curing results will be a reference and reference for further research to realize the creation of coconut fiber composite which is more useful. The process of making coconut fiber composites in this TA uses the press hand lay-up method, with alkalization soaking first and then post-curing treatment using an oven with a constant temperature of 100°C. To find the specifications and the percentage of this strength increase factor is by means of a tensile test with the parameters obtained: Ultimate Tensile Strength, strain, modulus of elasticity, and poisson ratio. With the highest result is at a duration of 3 hours worth 47.09 MPaKeywords: composite, Resin Polyester, coconut fiber, tensile test, heat curing, post-curing

Abstract

This program is aimed for teachers from SMK N 12 Bandung. Through this PKM (Community Service Program), it is expected that the training participants will gain insights and enhanced knowledge regarding aircraft maintenance, particularly the maintenance of gas turbine engines. The training was conducted at the Propulsion Laboratory, Aeronautical Engineering Hangar, Department of Mechanical Engineering, from October 12 to 16, 2021. The aircraft engine maintenance training began with a pre-test to assess participants' initial knowledge of aircraft engine maintenance. At the end of the training, a post-test was conducted to measure the improvement in their understanding and knowledge. The outcome of this PKM activity is a certificate of participation in the aircraft maintenance training, specifically focused on gas turbine engines.
