Charged EVs | FibreCoat’s AluCoat composite EV battery case integrates EMI shielding, passive cooling

FibreCoat says it will unveil a next-generation composite battery-case concept for EVs at JEC World 2026 in Paris (March 10-12), developed with composite manufacturer Coleitec and engineering consultancy Forward Engineering. The company’s approach uses its AluCoat material—an aluminum-coated fiber yarn—to add conductivity and functional layers directly into the composite, rather than relying on foils, plates or sprayed coatings applied as secondary steps.

According to FibreCoat, the component integrates woven fabric made from AluCoat yarn into a composite structure produced using Coleitec’s HP-RTM (high-pressure resin transfer molding) process. The company says the material-level approach can provide integrated electromagnetic interference shielding, improved fire protection, and passive cooling effects, while reducing production steps, complexity and carbon footprint.

Multiple prototypes were manufactured on Coleitec’s industrial HP-RTM line as part of a joint development program. “During the HP‑RTM production trials, we saw how AluCoat integrates smoothly into established composite processes while adding real functional value,” said Coleitec CTO Bin Wei. “Achieving this level of functionality without changing the existing production process makes AluCoat a very strong candidate for broader industrial adoption.”
