Studi Pengujian SEM (Scanning Electron Microscopy) Komposit Bermatrik Ebonit Dengan Kandungan Sulfur 40 Phr Yang Diperkuat Serat Rami Dan Bambu Dengan Kandungan Masing-Masing 30 Phr

Plastic is a common material that is often used to manufacture the product in an industry, especially the automotive industry. However, plastic has the disadvantage that the difficulty of the decomposition of waste that take a long time. It needs a better substitute material of plastic that is composite. Composite is a better solution because the constituent materials used can use natural materials, ranging from fibers and matrix. This is what makes the composite an environmentally friendly material that is biodegradable and does not cause the problems of waste. And the method of testing done on this composite is SEM (Scanning Electron Microscopy), in which the purpose of the test is to look at the microstructure of the composite. From the observation of micro structure capable of showing bonding characteristics of the constituent fibers that reinforce composites. For composites used in this study using ebonite matrix with fiber in the form of Rami and Bamboo. SEM test results show that the fiber bonding glue with ebonite Rami more than the bond of Bamboo fiber is seen to be apart of ebonite. Keywords : Composite, Natural Fibers, SE

Study Pengujian SEM ( Scaning Electron Microscopy ) Pada Ebonit Dengan Kandungan Sulfur 35PHR, Komposit Bermatrik Ebonit Diperkuat Serat Bambu 20PHR Dan 40PHR Serta Spion Honda Scoopy Sebagai Pembanding

Composite is a combination of two or more pieces of material elements which are combined into one to get a new, more useful material and its constituent elements are still distinguishable. In Indonesia where natural resources such as rubber and natural fibers are very abundant so the potential for developing a composite derived from natural materials that are environmentally friendly is wide open. One of the plants that can grow almost throughout the territory of Indonesia is bamboo, so it can be developed into new materials that are more useful and high quality. One of the way is making composite natural fiber reinforced matrix ebonite bamboo. Because the basis of this study tested SEM (Scanning Electron Microscopy) against ebonite with a sulfur content 35phr, fiber-reinforced composites with matrix ebonite bamboo 20phr and 40phr as well as on the mirror Honda Scoopy. This study was done to improve kwalias of a composite material derived from natural materials especially ebonite and bamboo fiber. The results of this study were observed from SEM images ebonite has three distinct layers, composite with matrix ebonite 20phr bamboo fiber reinforced bonds between matrix and ebonite not perfect. Ebonite with matrix fiber reinforced composites 40phr bamboo fiber bonding with very strong matrix and the surface of the rear view mirror Honda Scoopy is very tight and there is no porosit

Reverse Engineering Body Fender Mobil Esemka Rajawali Ii Dengan Membandingkan Hasil Pengukuran Menggunakan Coordinate Measuring Manual Machine Dan Laser Scanner Articulated Measurement Arms

This research uses reverse engineering method which aims to get 3D surface fender images of Esemka Rajawali II car and compare the result of fender measurement by using two steps of measurement (scanning). The first step is the measurement on the Esemka Rajawali II car fender using a manual 3D measuring instrument, while the second step is the measurement of Esemka Rajawali II car fender using 3D Laser Scanner Articulated Measurement Arms (LSAMA). Data obtained from the above point of coordinates (point cloud) x, y and z, which then the data point coordinates are inserted into softwere solidworks to create images of 3D fender part of the car surface esemka Rajawali II. After the process of making a 3D part surface fender image completed, the next stage compares the results of the two measuring instruments. The point (coordinate) of the fender component is the assist point used to explain the shape of the surface of the fender. The number of points used will affect the shape of the resulting fender, it is caused between the point one or the other point connected through the line before the surface on softwere solidworks. The number of points and the location of the point is randomly assigned to the fender component. Of the two measuring tools are 3D (LSAMA) and manual 3D measuring instruments, using the same number of koodinat points. Using 3D (LSAMA) has a better measurement precision than a manual 3D measuring instrument
