Can Polymer-Matrix Composites Survive beyond the Degradation Temperature of the Matrix?

Future mobility technologies such as Urban Air Mobility (UAM) and Advanced Air Mobility (AAM) are expanding transportation into three-dimensional airspace. As these platforms evolve from battery-powered eVTOLs to hydrogen-based hybrid propulsion systems, they must endure higher operating temperatures, often exceeding 400–600 °C. This creates a pressing need for structural materials that combine thermal resistance with lightweight performance.

While carbon fiber-reinforced polymers (CFRPs) offer excellent strength-to-weight ratios, their polymer matrices typically degrade under high heat. Metals like aluminum and titanium are currently used in thermal zones, but their weight and cost hinder further innovation.

This study proposes a new class of lightweight composites with enhanced thermal stability for application in high-temperature regions of hybrid aerial vehicles. By using high-Tg, low-viscosity resin systems and thermally functional fillers, we aim to replace heavy metal components while maintaining structural integrity. These developments will support the next generation of hydrogen-powered aircraft by improving heat tolerance without sacrificing weight efficiency.
