Abstract

Vehicle construction requires strong joints to connect various materials. Many connections are made by welding, riveting, and adhesive bonding. Adhesive bonding has the advantages of efficiency, corrosion resistance, and ease of application. This research aims to analyze the effect of using sikaflex (SK) - epoxy (EP) mixed adhesive on the shear tensile strength of single lap joint aluminum. The material used was aluminum 5083 and sika flex and epoxy adhesives with an adhesive thickness of 0.4 mm, as well as variations in surface pattern treatment. The results showed that the highest tensile strength and modulus of elasticity in the variation of 10% SK: 90% EP with surface pattern 90º cross-type amounted to 2.34 MPa and 79.29 MPa. The highest strain was in the variation of 30% SK and 70% EP composition with a 0º horizontal surface pattern of 0.0466. The failure modes that occur are cohesive failure and thin-layer cohesive failure.

Abstract

Industrial growth, especially iron and steel, is growing rapidly today. In this industry, welding is an important aspect that needs to be considered to achieve results that meet standards. The SMAW welding process is often used to improve joint quality. This study aims to explore the effect of the combination of current strength and electrode diameter on the hardness and tensile strength of galvanized steel welded with an E6013 electrode. The results showed that the combination of current strength of 80 A and electrode diameter of 2.6 mm produced the highest hardness value of 221.5 VHN and the largest tensile strength of 358.16 MPa, with ferrite dominance in the microstructure.

Abstract

Composite is a material made from two or more combined substances that are bound together. Typically, biomaterials are made of metals. However, metals have a high elastic modulus, which leads to stress shielding, and they are expensive because metals are non-renewable materials. This study aims to analyze the mechanical strength of composites made from ramie fiber, hydroxyapatite, and UHMWPE as a potential non-metallic biomaterial, with variations in composition of 13%: 0%: 87%, 6.5%: 6.5%: 87%, and 0%: 13%: 87%. The composites were manufactured using a hot press at a temperature of 190°C, pressure of 100 bar, and a holding time of 15 minutes. The test results showed the composite containing 13% ramie fiber having the highest impact toughness and tensile strength values of 0.055 J/mm² and 10.75Mpa.
