Carbon-fiber composites, or fiber-reinforced polymers, are strong, lightweight materials that can help lower fuel consumption and reduce emissions in critical areas such as transportation. However, unlike metal competitors, carbon-fiber composites are not typically recyclable, meaning wider adoption could present waste challenges.
Our goal is to extend the lifecycle of these materials by making reuse possible without sacrificing performance, said ORNLs Md Anisur Rahman.
The teams approach incorporates dynamic covalent bonds that are reversible, enabling both carbon fiber and polymer recycling. The new polymer , a sharp contrast to previously reported polymers.
ORNLs carbon-fiber composites enable fast processing and can be repaired or reprocessed multiple times, opening pathways to circular, low-carbon manufacturing, said ORNLs Tomonori Saito.
