Para-Aramid Honeycomb Core is a lightweight, high-strength core material manufactured using advanced processes from high-performance para-aramid (Also known as KEVLAR) fibre paper. Its unique hexagonal honeycomb structure endows the product with exceptional specific strength and specific stiffness, delivering outstanding compressive and flexible resistance while achieving ultimate lightweight. This product inherits para-aramid's inherent superior properties: high-temperature resistance, flame resistance with self-extinguishing characteristics, fatigue resistance, and excellent electrical insulation alongside electromagnetic wave permeability. It maintains stable performance, ensuring long-term reliable operation in demanding environments.
