Mechanical Properties and Phase Transformations in Resistance Spot Welded Dissimilar Joints of AISI409M/AISI301 Steel

Abstract

Objectives: This paper is about the mechanical characters of biaxial braided carbon fiber nanocomposites. Methods/Statistical Analysis: Hand layup technique is used for fabrication of biaxial braided fiber nanocomposites. Seven samples have been prepared with Unfilled, TiO2 (1, 3 & 5wt %) and Nanoclay (1, 3 & 5 wt %). The above nanoparticles were mixed in the epoxy resin using magnetic stirrer. Mechanical properties (tensile, flexural and impact) were carried out. Findings: The experimental outcomes showed that the mechanical characterization of unfilled biaxial braided fiber nanocomposite material was lower than the TiO2 (1, 3 & 5wt %) and nanoclay (1, 3 & 5 wt %) biaxial braided fiber nanocomposite materials. 3wt% TiO2 and 3wt% nanoclay composite materials showed better improvement in the mechanical characters. However, 3wt% nanoclay composite material showed very excellent improvement in the mechanical characters than 3wt% TiO2. This is due to nanoclay particles have higher strength and higher modulus than TiO2 particles. Application/Improvements: The developed biaxial braided fiber nanocomposite materials were used in the field of aeronautics, automotive and space recreation products because of their excellent properties, light weight, corrosion resistance, high energy absorption and excellent strength characteristics.
