Abstract

Application of green composites material is aerial egineering. Advantages of green composites material are lightweight and relatively strong. This reason that makes green composites can be applied in Unmanned Aerial Vehicle (UAV). In this study, material of quadcopter frame was composites material that made of waste material from styrofoam, bagasse and eggshell. Styrofoam was used as binder of composite material. Bagasse and eggshell was used as reinforcement in green composite material. The investigation focused on effect of volume fraction on flying time of quadcopter that made of green composites material. This study showed that addition of eggshell powder in composites up 25% by volume fraction, result in decreasing the flying time of quadcopter. Addition of eggshell powder in composites up 25% by volume fraction, result in decreasing the porous of green composite. Porous structure affect the flying time of quadcopter based on green composite materials that made of waste material from styrofoam, bagasse and eggshell. Green composite based on styrofoam, bagasse and eggshell can be applied in Unmanned Aerial Vehicle (UAV) materials.

Abstract

The composites made from natural fibers have been widely used in the engineering field because the natural fiber-based composites have lightweight nature, relatively strong and environmentally friendly. The use the synthetic fiber-based composites reduced to obtain the environmentally friendly composites. In this study, the use synthetic fibers (fiberglass) reduced by adding coconut fiber (coir) on the composite mix. Composites in this study using the volume fraction of hybrid fiber 12% fiberglass and 18% coir. The volume fraction of fibers and epoxy hybrid is 30:70. This study aims to determine changes in stiffness of the hybrid composites due to dynamic loads. Hybrid composite loaded by 500, 1000, 1500, and 2000 cycles of the dynamic load. The test results show degradation of the rigidity of the hybrid composite. The stiffness decrease like presented by the ratio of E/Eo. The number of cycles of the dynamic load causes a decrease in stiffness hybrid composites. The stiffness of hybrid composites decrease because of dynamic load treatment reaches 30%.

Abstract

Salah satu pemanfaatan komposit adalah sebagai material blade turbin angin. Ini disebabkan komposit memiliki sifat ringan dan relatif kuat. Namun, komposit yang berbasis serat sintesis dikurangi penggunaannya untuk mendapatkan sifat ramah lingkungan. Sehingga penelitian ini menggunakan serat hibrid yang terdiri dari 60% fiberglass dan 40% coir. Fraksi volume antara serat hibrid dan epoksi adalah 30:70. Penelitian ini bertujuan untuk mengetahui trendline perubahan sifat mekanik dari komposit akibat pengaruh lingkungan (moisture content dan thermal shock) karena komposit akan diaplikasikan sebagai bahan blade turbin angin. Komposit direndam dalam air dengan variasi perendaman 6, 12, 18, dan 24 jam untuk mengetahui pengaruh moisture content. Pengaruh thermal shock diuji dengan pemanasan 800C dan pendinginan dengan siklus 5, 10, 15, dan 20. Hasil pengujian menunjukkan degradasi kekuatan tarik dan ketangguhan impak komposit. Penurunan kekuatan tarik akibat pengaruh perendaman untuk masing-masing variasi sebesar 6.63%, 15.60%, 22.65% dan 28,61%. Penurunan kekuatan tarik akibat pengaruh siklus thermal shock berturut-turut 3.83%, 9.60%, 17.28%, dan 4.98%. Penurunan ketangguhan impak akibat pengaruh perendaman untuk masing-masing variasi sebesar 40.66%, 44.00%, 47.33% dan 48.00%. Penurunan ketangguhan impak akibat siklus thermal shock berturut-turut 24.67%, 46.67%, 51.33%, dan 51.33%. Degradasi kekuatan komposit disebabkan terjadinya pull-out, delaminasi, dan perubahan struktur komposit menjadi lebih getas (brittle).

Abstract

The excessive use of fossil fuels has many negative impacts on the environment and health. Many studies have been conducted to find solutions to this problem, such as the use of oxy-hydrogen gas (HHO) as an alternative to reduce the use of fossil fuels as a source of energy in vehicles and other applications. The objective of this research is to compare the performance of a wet type HHO generator using two types of electrodes, stainless steel plate and galvanized steel plate. Both generators use nine electrodes with dimensions of 130 mm x 60 mm consisting of two plates at the positive pole (anode), one plate at the negative pole (cathode), and six neutral plates. Calculation of the power consumed by the HHO generators, the flow rate of the gas produced, and the efficiency of these generators are carried out to compare the performance of both HHO generators. The results showed that the performance of the HHO generator using stainless steel plate as an electrode was better than galvanized steel which was indicated by a higher efficiency value.

Abstract

One of the most widely used and applied technics materials today is a composite material based on nature. Natural composites are lightweight and relatively strong and environmentally friendly, so composites based on synthetic fibers are reduced in use. This study uses constituent materials derived from shells and bunches of palm oil plant crops that function as reinforcement. Shells and fibers from empty bunch of oil palm plants are made in the form of powder. Matrix used in this research was polyester resin and epoxy resin. The volume fraction between the reinforcement and the matrix is 50:50. The fabrication process of this environmentally friendly composite is compression molding with a pressure load of 30 kg/cm2. This study aims to determine the effect of the type of composite materials on physical and thermal properties of the natural composite. The results show that natural composites are high density composites. The highest density of palm shell/polyester composite is 1,223 g/cm3 and the lowest density of oil palm empty bunch/epoxy composite is 1,021 g/cm3. The highest thermal conductivity of oil palm shell/polyester composite is 0,28 W/m.K. Thermal conductivity composite value is more influenced by binder/matrix of composites.
