Lightweight research benefits the environment

Published: 5 May 2014

Materials scientist Andrejs Pupurs at Luleå University of Technology is one of six promising young scientists who have been accepted to LIGHTer. The purpose of LIGHTer, one of Sweden's five priority strategic innovation areas, is to strengthen Swedish industry by developing expertise in lightweight materials.

– Through modeling, we can estimate and optimize various properties of materials and products. If the models are good, we can reduce experimental tests, thus saving lots of time and money, says Andrejs Pupurs, researchers in polymer engineering materials at Luleå University of Technology.

Lightweight materials, such as polymer composites, also has a positive impact on the environment.


– Reducing weight means reduced carbon emissions from for instance aircrafts and cars. For example, in the new Boeing 787 Dreamliner, 80 percent of the material is composed of polymer composites.

Andrejs Pupurs will conduct research in the first (and largest) of LIGHTer's seven focus areas, "Modelling of the relationships and interdependencies between microstructure, processing and performance for lightweight design". Through LIGHTer, Andrejs Pupurs receives 40 percent financing for at least four years. He appreciates the opportunity and see the possibilities. 

– It's exciting to be part of something as big and strategically important as LIGHTer. My research network will be expanded significantly and I look forward to an interdisciplinary collaboration with other researchers in the cluster, says Andrejs Pupurs.

The area of modeling in LIGHTer is led by Luleå University of Technology and Lars-Erik Lindgren, professor in material mechanics.
