Polymer composites have been widely used in the aviation, aerospace, automotive, military, medical, agricultural and industrial fields due to their excellent mechanical properties, heat resistance, flame retardant, impact resistance and corrosion resistance. In general, their manufacturing process is one of the key factors affecting the life cycle of polymer composites. This article provides an overview of typical manufacturing technologies, including surface coating, additive manufacturing and magnetic pulse powder compaction, which are normally used to reduce the failure behaviour of polymer composites in service so that the quality of composite products can be improved. Advanced polymer composite powder manufacturing processes, the processing mechanism and experimental methods are described, and the influence of different manufacturing processes on the moulding quality is revealed. This investigation can provide suitable methods for the selection of manufacturing technology to improve the quality of polymer composite products.

“…5 Notably, Huang et al 6 utilized ANSYS software to analyze the displacement, velocity, and stress of aluminum powder during the low-voltage EM compaction method. Cui et al 7 investigated the spring-back behavior of copper powder compacts produced using EM pulse compaction and analyzed it with MSC Marc software. To quantitatively replicate the compaction response of pharmaceutical powders, Han et al 8 employed a modified Drucker-Prager Cap constitutive model.…”

Electromagnetic axial powder compaction (EMAPC) uses strong magnetic fields to compact powder metallurgy components at high speeds. Lorentz forces accelerate the punch to compact powder in EMAPC. Thus, high magnetic fields cause powder deformations in microseconds. Therefore, measuring the compact height, magnetic field distribution, and compaction velocity was difficult. No literature has reported EMAPC finite element (FE) modeling. Thus, an LS-DYNA multi-physics solver-based FE 3D model has been developed to study SS316s EMAPC. A cylindrical SS316 sample was simulated for EMAPC at various discharge energies. The powder-compressed sample's final deformation was predicted through simulation. To characterize compacted samples, sintered samples were studied for density, porosity, and microhardness. Compressed samples were microscopically examined using optical microscopy. Increased discharge energy lowers height, increases density, and microhardness. FE analysis can be used to optimize EMAPC process parameters for powder compact density and porosity.
