Today the use of natural fiber composites has been widely used in various industrial fields. One of the natural fibers that have the potential to be developed is ramie fiber. The purpose of this study is to see the effect of the number of reinforcing layers and variations in the diameter of the drill bit on the laminate factor. The research method in making composite panels used the hand lay-up method and in measuring the magnitude of the delamination factor, the EPSON L360 scan tool was used to take high-resolution macro photos of 2400 DPI and the measurement of the radius of damage using the image pro-plus v4.5 application. Research results in the Delamination factor are influenced by machining parameters and reinforcement of the material. The size of the drill tool diameter affects the cutting contact area of the ramie fiber composite. The larger the contact area, the range of the delamination damage area also increases. The rate of delamination damage is greater if the calculation of the force acting on the maximum cutting contact area with a high feed rate. While the reinforcement of the material with the addition of the number of reinforcing layers provides greater momentum/impetus due to the calculation of the forces acting at the time of drilling. The amount of reaction energy that arises is absorbed by the composite material so that the bond strength of the matrix and fiber decreases. This event causes the delamination factor in composites with more reinforcing layers to be higher. [ABSTRACT FROM AUTHOR] |
