Abstract
<div class="WordSection1"><p>Adhesive joint is one of the material joining techniques using a low temperature with the help of polymer adhesives to connect a material. This connection is widely used in infrastructure, automotive and electronics industries. This research was conducted to determine the effect of filler on shear strength and electrical conductivity on epoxy-based aluminum connections. The fillers used were aluminum powder, iron powder, copper powder with a grain size of 0.071 mm each and nanogold particles in liquid form. The connection type used is a single lap joint with an end tab modification at the end of the connection. The highest shear strength value is in the joint without the addition of filler of 3.17 MPa and the lowest value is in the connection with the addition of aluminum powder filler of 1.14 MPa. The highest value of electrical conductivity was obtained in epoxy mix with nanogold particle filler which was worth 13.1 S / m and the value for epoxy without the addition of filler was not detected because the resistance was too large. This shows that the addition of filler has an effect on the value of shear strength, which is to reduce the value of the shear strength, while for testing the conductivity of electricity the addition of filler has an effect to provide electric properties on epoxy.</p></div>
Highlights
In the development of technology and the industrial world, currently many new products consisting of a combination of new materials that need to be prepared in accordance with the specifications and characteristics [1]
Adhesive joints themselves are starting to be widely used in the industrial world as a way of joining materials because they are strong, do not have overdesign and can be used in metal and non-metal materials [2,3]
EXPERIMENTAL The material used in this research is a series 1 aluminum plate which is used as an adhesion to joints, epoxy-based adhesives under the brand name Dextone and fillers with various aluminum powders, iron powders, copper powders with the grain size is 0.071 mm each and nanogold particle liquid
Summary
In the development of technology and the industrial world, currently many new products consisting of a combination of new materials that need to be prepared in accordance with the specifications and characteristics [1]. This epoxy connection can be modified by adding powder material to the epoxy mixture The purpose of this addition is to increase the value of thermal conductivity and mechanical strength at the joint. The effect of adding powder material to the epoxy glue can increase the value of thermal conductivity and mechanical strength, and can increase the value of electrical conductivity at the connection [7]. This research is focused on the effect of powder material on epoxy mixes on shear strength and electrical conductivity on aluminum joints. EXPERIMENTAL The material used in this research is a series 1 aluminum plate which is used as an adhesion to joints, epoxy-based adhesives under the brand name Dextone and fillers with various aluminum powders, iron powders, copper powders with the grain size is 0.071 mm each and nanogold particle liquid. The making of electrical conductivity test specimens were made 5 specimens with details of four using the addition of filler and one specimen without the addition of filler which was inserted in a beam-shaped silicone mold with a size of 44 mm x 10 mm x 10 mm such as shown in Figure 1 with a dry waiting time of 24 hours
