| Abstract Scope |
Polyamide 4.6 is classified as a high-temperature thermoplastic because of its service temperatures of up to 175°C, bringing them close to high-temperature plastics like PPS or PEEK. Due to its high-temperature capability and price/performance ratio, Polyamide 4.6 is considered viable in developing high-performance bonded magnets by serving as a binder/matrix to magnetic powders/fillers to form multifunctional magneto polymeric composites that offer superior properties to conventional materials. The thermal integrity of the polyamide 4.6 matrix would lock the orientation of the magnetic particles in place by limiting the sporadic motion that could arise due to heat which causes misalignment of the magnetic domains and a decrease in magnetism. Strontium ferrite magnetic powders were compounded with polyamide 4.6 using a co-rotating twin screw extruder. Thermal, mechanical, and magnetic characterization was performed on 3D printed samples using Simultaneous Differential Thermogravimetry, MTS Servo hydraulic test system, and Vibrating Sample Magnetometer, respectively.
