US scientists develop self-healing plastic stronger than steel

Scientists have developed a revolutionary carbon-fiber plastic composite called ATSP that heals itself when heated and exceeds steel's strength while being lighter than aluminum. This material, created by researchers at Texas A&M and University of Tulsa, can repair damage in aircraft parts and restore vehicle shapes after collisions while remaining recyclable. Testing showed ATSP endured hundreds of stress cycles, with samples regaining nearly full strength after damage-healing cycles, offering sustainable alternatives for defense, aerospace, and automotive applications.
