The US Department of Energy (DOE) is to partner with structural adhesives technology company PPG in a project set to use supercomputing in the development of suitable adhesives for use in assembling vehicles using lightweight structural materials to boost energy efficiency.

PPG announced it will collaborate with the DOE’s Lawrence Livermore and Pacific Northwest National Laboratories in developing computer-based models charting the influence of water as a guide to the aging patterns of adhesives designed to bond the lightweight materials currently being considered as possible structural materials for the new breed of energy-efficient vehicles. The materials being considered include aluminum, carbon-fiber composites, magnesium and high-strength steel.

According to PPG, new chemistries would be needed to produce the sort of adhesives required to lessen the chance of corrosion and deal with any thermal expansion problems which can occur when bonding dissimilar materials. Using traditional methods to acquire the necessary knowledge by iterative formulation and testing involves a lengthy process, but PPG reports that computer models, on the other hand, could cut the testing time down by up to 75%, so speeding up vehicle manufacturers’ development programs.
