Özet
Effective thermal management is the critical bottleneck in high-density battery safety and performance. While metals like aluminum are traditional benchmarks for heat dissipation, their high-density and manufacturing constraints limit the efficiency of modern, weight-sensitive systems. This study addresses this gap by developing and characterizing a new class of thermal metamaterials that integrate high-performance polymer composites with additive manufacturing (AM) to achieve unprecedented control of heat flow. The innovation lies in the synergy between a custom-formulated polyamide-6/synthetic graphite (PA6-40SG) filament and topology-optimized geometric architectures. By loading 40 wt% SG, the composite’s in-plane thermal conductivity was increased to 15.04 W/m·K, transforming a naturally insulating polymer into a highly conductive medium. Beyond material enhancement, this work implements a dual-phase optimization strategy that integrates numerical thermal modeling with metamaterial-based heat-flow control. The impact of this research is demonstrated through the fabrication of a battery enclosure cover that achieves thermal performance comparable to that of aluminum while reducing weight by 30%. These results prove that engineered polymer metamaterials can successfully replace metallic components in demanding environments. This study provides a scalable framework for designing lightweight, cost-effective, and geometrically complex thermal management solutions across the automotive, aerospace, and electronics industries.
