Maltese researchers have developed a new way of making a special sort of foam, which could help make cars safer.

The researchers have devised a simpler way of making what are known as high value-added, auxetic foams from ordinary foam. These foams have the unusual property of getting fatter when stretched rather than thinner.

They are harder to indent on impact, providing extra support during sudden collisions, which makes them especially suitable to use in car seats and protective equipment such as crash helmets. In fact, not only are they better than conventional foams in terms of protection but also in terms of comfort. The safety aspect is the biggest selling point.

"Such added protection could make the difference between life and death should one be involved in a traffic accident" said lead researcher Joseph Grima.

"Anyone who has been involved in care or motorcycle accidents will appreciate the need for materials such as ours, which can help minimise the trauma that results following sudden impacts."

The work of the team, that includes co-workers Daphne Attard, Ruben Gatt and Richard Cassar, all from the Chemistry Department at the University of Malta, was featured on the front cover of the July issue of a prestigious industry journal, the Advanced Engineering Materials.

The team, made a presentation to Prime Minister Lawrence Gonzi who congratulated them and said this was evidence of Malta's potential in becoming a centre of excellence based on a knowledge economy.

He welcomed the joint venture with industry in this research project and stressed the importance of such collaboration for Malta to reach its targets.
