Work Package 4

In this WP, the manufacture of all metal/composite joints will be undertaken. The work will examine steel aluminium and titanium alloys to fibre reinforced composites suitable for a range of applications.

Task 4.1 – Manufacture of steel/composite joints

The main applications of steel composite joints are envisaged for marine and offshore applications. This task will undertake the manufacture of lap shear joints (for tensile, fatigue, impact and environmental exposure tests) and samples for pull off tests. The task will also undertake the surface preparation of the substrate and the up-scaling of CNT application methods developed in WP2.

Task 4.2 – Manufacture of aluminium/composite joints

Aluminium/composite joints are envisaged for marine, aerospace, and surface transport applications (mainly rail). This task will undertake the manufacture of lap shear joints (for tensile, fatigue, impact and environmental exposure tests) and samples for pull off tests. The task will also undertake the surface preparation of the

substrate and the up-scaling of CNT application methods developed in WP2. In addition to standard test specimen manufacture the task will undertake the manufacture of specific specimen designs that will be suggested by the end users involved in this consortium.

Task 4.3 – Manufacture of prefabricated metal/composite joints

The titanium/composite joints are a very novel design that is expected to have applications in several sectors where lightweighting is essential. This task will undertake both the manufacture of the titanium adherends as well as the joint itself. The work includes manufacture of lap shear joints (for tensile, fatigue, impact and environmental exposure tests) and samples for pull off tests. The task will also undertake the surface preparation of the substrates and the preparation of the dry fabric preforms as well as the up-scaling of the CNT application methods developed in WP2.

Task 4.4 – Development of NDE techniques for quality control of metal composite joints

This task will undertake the development of reliable NDE techniques for quality control of the metal/ composite joints. Metal/composite joints produced from different metals to fibre reinforced composites, multi-adhesive joints, as well as lap shear joint type presents the great challenge to the NDE technique to be implemented.
