Analisis Kekuatan Mekanik Komposit Polimer Diperkuat Serbuk Kulit Kerang

Abstract

In recent decades, the development of composite material technology has continued to increase rapidly and has been used for various applications as an alternative material to replace metal. In line with growing environmental issues, the utilization of natural materials which are abundant in nature and easy to find is the main priority for composite building materials. In this study, shell powder was used as a reinforcing material for epoxy polymer composites. The aims of this study were to obtain the average compressive, tensile, and flexural strength of shell powder-reinforced polymer composite materials, to calculate the distribution of test results using the PDF method, and to calculate the contribution of shell powder to the mechanical properties mentioned using the ANOVA method. The tensile, compressive, and flexural test specimens follow the test specimen standards of ASTM D638, ASTM D7264, and ASTM D695 respectively. The composition of shell powder consists of 10%, 30%, and 50%. Testing of these mechanical properties using a UTM-type hydraulic test equipment model WEW-300D with a capacity of 300 kN. The test results show an increase in the mechanical properties of the material. The increase occurred in compressive and flexural strength where the composition was given up to 30% and 50%, namely between 120 -125 MPa. However, increasing the composition of shell powder at 30% and 50% actually resulted in a decrease in tensile strength between 12 -9 MPa. Finally, based on the results of ANOVA analysis, it was shown that the addition of shell powder as a reinforcement for polymer composites significantly improved their mechanical properties.

The Influence of e-glass epoxy composite laminate material application on the crack pattern of cylinder concrete column cross-section

“…The development of stronger, lighter, and more durable materials has benefited from the use of composites in a number of industries, including construction, automotive, and aerospace. It is possible to explore creative composite development to satisfy a variety of application objectives by comprehending the characteristics of fiber and matrix materials as well as their interactions [14].…”

Analisis Pengaruh Panas dan Beban terhadap Kerusakan Traveling Grate pada Boiler Di PLTU Tembilahan 2x7 MW

“…Selain adanya tegangan pada balok traveling grate yang berposisi di furnace, hal ini menyebabkan adanya perpindahan panas yang menyebabkan thermal stress. Thermal stress adalah sebuah fenomena dimana material yang dikenai gaya, mengalami penurunan kekuatan yang signifikan dikarenakan adanya pemuaian material yang diakibatkan oleh sumber panas [7]- [9]. Hal ini membuat material menjadi lebih lemah dari sifat dasarnya.…”
