Thermoplastic-based bonded magnets combine the cost-effectiveness, low density, and manufacturing flexibility of conventional engineering plastics with the unique characteristics of magnetic powders/fillers to form multifunctional magneto polymeric composites that offer superior properties to conventional materials. At higher temperatures, magnetic properties change significantly and the particles within the magnetic powders experience sporadic motion due to the heat which causes misalignment of the magnetic domains, leading to a decrease in magnetism. Due to these adverse temperature effects, high-performance polymers such as polyetheretherketone (PEEK), polyetherimide (PEI) or other high-temperature thermoplastics have been considered suitable matrix for the magnetic fillers, thereby creating a much wider usage for magneto polymeric composite in applications that requires higher temperature (typically above 175 oC). Thus, a high-performance polyamide bonded magnet will be fabricated via the twin extrusion technology for Magnetic Field Assisted Additive Manufacturing (MFAAM) process. This bonded magnet will possess a good combination of thermal stability, structural integrity, and magnetic performance that can be viable for high-performance applications such as sensors, actuators, motors, and generators.

Oluwasola received his BS in Materials Engineering from Obafemi Awolowo University, Nigeria, and MS in Manufacturing Engineering from Texas State University. He is currently pursuing a Ph.D. in Materials Science, Engineering, and Commercialization at Texas State University. Oluwasola’s research focuses on the manufacturing and characterization of polymer nanocomposite filaments with multifunctional properties for 3D printed parts used in electrical and magnetic applications. He is working on his Ph.D. dissertation that focuses on developing high-performance bonded magnets for the Magnetic Field Assisted Additive Manufacturing (MFAAM) process.
