A research team led by Associate Professor Leong Kah Fai from NTU’s School of Mechanical and Aerospace Engineering has developed prototype helmets that can offer the same level of protection as high-end helmet ($400~), but cost only as much as a mid-tier one($100-$150~).
Instead of the polycarbonate shell that is used in conventional bike helmets, a new thermoplastic resin -- Elium, is used.
Elium is reinforced with carbon fibre, making it tougher and less brittle, and allows the helmet shell to absorb more impact energy over a longer period, while also dissipating it evenly throughout the helmet. This results in less overall force reaching the head, thus reducing the chances of critical injury.
