Researchers at Perm National Research Polytechnic University (PNRPU) have achieved a notable improvement in the processing efficiency of next-generation polymer composites. This advancement was shared with socialbites.ca by the university’s press service, underscoring the institution’s ongoing commitment to practical, high-impact materials science.
Polymer composites play a crucial role in manufacturing components for gas turbine engines, unmanned aerial systems, and shell tubes. Traditionally, finishing these parts relied heavily on mechanical cutting and milling with blades. While effective, this approach becomes expensive and technically challenging when the geometry includes intricate grooves and precisely placed holes.
The research team from PNRPU has introduced an alternative technique based on electrical discharge processing. The method involves removing material by brief electrical pulses that melt and vaporize material from the workpiece surface. A key innovation was addressing the limited electrical conductivity of polymers by integrating thin titanium plates into the parts, which enhances current flow and improves processing stability.
As part of their investigation, the scientists examined the three-dimensional structure of the composite using computed tomography. The findings showed that the new processing approach can successfully shape the polymer matrix, but also highlighted that selecting inappropriate process parameters can cause surface melting or damage. The team is now focused on identifying optimal settings that balance material removal efficiency with surface integrity.
Timur Ablyaz, director of the Advanced School of Aviation Engine Engineering, emphasized that as polymer composite materials become more widely used in construction and specialized engineering, it is essential to develop processing methods that are both technologically effective and scalable. The researchers and young engineers involved in this effort have articulated foundational principles describing how processing modes influence surface quality. Ongoing work aims to refine the technique and extend studies on the cyclical durability of polymer composite components after electrical discharge treatment, with a broader program of testing planned to assess long-term performance under real-world operating conditions.
In related developments, Russian scientists have previously announced substantial progress in water purification technologies, including the creation of biomaterials capable of removing heavy metals from water. This broader context highlights a national momentum toward advancing material science applications that span energy, defense, and environmental protection, with the Perm team contributing a practical, processing-focused solution for polymer composites.
