Team develops eco-friendly, flame-retardant carbon plastic ideal for recycling

A flame-retardant carbon-fiber-reinforced composite material has been developed. Korea Institute of Science and Technology (KIST) announced that a research team from its Institute of Advanced Composite Materials, headed by Dr. Yong chae Jung used plant-originated tannic acid to develop a flame-retardant carbon fiber-reinforced plastic (CFRP), and also presented a method for its eco-friendly recycling. CFRP, a composite material that contains carbon fiber, which is about four times lighter than steel yet 10 times stronger, is widely used in the aerospace, automotive, shipbuilding, and sports equipment industries. Structurally, CFRP is made up of carbon fiber and epoxy resin, which serve functions in this composite material similar to the respective roles that reinforcing rods and cement play in concrete structures. To achieve mechanical rigidity, the binding of carbon fiber and epoxy resin in CFRP must be strong. Moreover, CFRP must be fire-safe, as it is used for purposes closely related to everyday life, e.g., use as a construction material. To induce these traits in CFRP, sometimes it is synthesized with additives. Read more....
