Cobalt phytate coating on carbon fabric cuts epoxy composite fire risk
Source: Advanced Composites and Hybrid Materials, "Bio-inspired interfacial engineering of carbon fabric@ZIF-67@cobalt phytate towards enhanced fire safety and mechanical properties of epoxy composites", published 11 November 2026.
What the source says
Laboratory carbon-fabric epoxy composites with a fabric@ZIF-67@cobalt phytate interface were tested for fire and mechanical performance. They reached a 35.6% limiting oxygen index, a UL-94 V-0 rating and a 63.4% lower peak heat release rate, with tensile strength 35.0% higher.
Allbase view
A lab-scale treatment of carbon fabric gave epoxy laminates better flame resistance and strength together. No production data or cost yet, so nothing to act on yet for aerospace or industrial carbon-epoxy specifications.
