According to a report by the World Health Organization (WHO) in 2020, more than 60% of reported cases
Researchers from Nanyang TechnologicalThe University of Singapore has partnered with French company Arkema to develop a stronger and safer bicycle helmet using a combination of materials. The prototype new helmet absorbs energy on impact and reduces the likelihood of serious injury.
A new thermoplastic resin calledElium, developed by Arkema, one of NTU's industrial partners. The NTU team worked with Arkema engineers to develop the Elium molding process to produce more durable bicycle helmets.

Cycling helmets usually consist of twocomponents. The first is the outer shell, usually made from a mass-produced plastic such as polycarbonate. Beneath it is a layer of expanded polystyrene, the same material used in food packaging and takeout boxes.
New Composite Team Helmet Replacestraditional polycarbonate outer shell over carbon fiber reinforced Elium shell. This reinforcement makes the outer shell stronger, stiffer and less fragile than the polycarbonate shell.
These properties allow the outer shell to absorbmore impact energy for a longer time, and distribute it evenly throughout the helmet. As a result, the overall force on the head is reduced, thereby reducing the likelihood of critical injuries.
