  7. 10. Circularity in Thermal Recycling for Sustainable Carbon Fibers

    Author : Marina Corvo Alguacil; Roberts Joffe; Tommy Öman; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pyrolysis; carbon fiber; composites recycling; CFRP; polymer composites; sustainability; Polymeric Composite Materials; Polymera kompositmaterial;

    Abstract : The research field of composite materials is particularly fascinating due to the design freedom they offer and the infinite number of constituent combinations, including those that are already explored, and many more that are yet to be tried. One composite material that holds great potential contains carbon in its fiber shape. READ MORE
