There is a high demand for the design of lightweight energy efficient structures for transport applications in order to meet CO2 emissions targets set worldwide. To achieve this designers have introduced the concept of “hybrid” structures where two or more lightweight materials are used each possessing unique properties that when joined together result in high performance lightweight structures that would not have been possible if a single material was used.

This approach requires the development of joining techniques for materials with fundamentally different physical properties that will ensure the safe and reliable transfer of load between the constituent materials.

The SAFEJOINT project addresses this challenge by developing novel techniques for metal to metal and metal to composite joining as well as developing novel techniques for the non-destructive inspection and evaluation of such joints in order to enhance confidence to designers and end-users of hybrid structures of their through life safe performance.

The SAFEJOINT project is a 36 month project, which will aim to address the common joints in structural engineering applications such as:

Metal to metal joints

i. Aluminium alloy to different grade aluminium alloy joints

ii Aluminium alloy to magnesium alloy joints


Metal to composite joints

i. Steel to composite joints

ii Aluminium alloy to composite joints

iii Titanium to composite joints


The SAFEJOINT consortium having knowledge of past projects concerning joining of dissimilar materials in the EU and Internationally, will intriduce a number of innovations in joining technologies that will provide a significant step forward in this technology.
