Revolutionizing Mobility: South Korean Universities Unveil Cutting-Edge Material Advancements for Air and Road Travel
South Korean universities have developed a new composite material that could revolutionize air and road mobility. Researchers from Solutions to Electromagnetic Interference in Future-mobility (SEIF), Hanyang University, and Jeonbuk National University have created a self-reinforced composite (SRC) that uses only one type of polypropylene (PP) polymer, resulting in improved bonding and tensile strength, as well as impact resistance. In fact, the SRC they created had adhesive strength 333% greater than composites currently in use, while tensile strength was 228% greater and impact resistance was a staggering 2,700% higher. Apart from toughness, SRCs are lightweight, inexpensive, and have advantages in terms of disposal and recycling as the reinforcement and the base material are composed of the same material. Current manufacturing processes for SRCs involve mixing chemically different components, resulting in poorer physical properties and preventing recyclability. However, the Korean researchers found a successful way to control the melting point, fluidity, and impregnation by adjusting the chain structure of the polypropylene matrix through a four-axis extrusion process. The new material is being looked at as the next-generation composite material to replace carbon-fiber-reinforced composites used in vehicle and aircraft/drone bodies. With the new composite material, vehicles and aircrafts will be more fuel-efficient while significantly reducing carbon footprints. The development of this new material could pave the way for a more sustainable future in air and road mobility.
