D-JOINTS: Composite hybrid joints with electromagnetic compatibility

Background

The D-JOINTS project will provide the industry with novel design tools that can cope with demand for increased output while maintaining the required aerospace quality standards and more specifically increased complexity with reduced weight of the produced parts. The most important feature of the system will be the unique methodologies for modelling the EMC of structural aeronautical structural joints and improving the Lightning Strike Protection capabilities of modern airframe assemblies.

Objectives

• New innovative composite-metal joints with enhanced lightning strike protection systems
• Model the thermomechanical and electrical performance of reference geometry dissimilar joints using numerical analysis
• Improve dissimilar joints considering the electromagnetic performance
• Develop a sizing tool for composite hybrid joints
• Manufacture and test a composite nose part with the new dissimilar joints integrated in an aircraft structure

Benefits

The innovative joints as well as the design tool developed in D-JOINTS provide significant opportunities for improvement in lightning strike performance of joints and robustness of the overall structure. The combined progress in these two fronts make the overall potential improvement bigger than the sum of their parts as the ability to design with a user-friendly tool is enhanced by the incorporation of novel joining capabilities and the efficiency of novel joint designs is boosted by the possibility of exploring their capabilities in a structured and easy to use manner.

Brunel Composite Centre's Role

• Development of an electromagnetic simulation in order to model the indirect effects of the lightning strike
• Electrical conductivity characterisation campaign to address the surface resistance of joint materials and coatings, through thickness conductivity of adherents, including tufted configuration and screening effectiveness
• Electrical current and Lorentz forces calculations that will be integrated to the sizing tool and will be coupled with the thermal and mechanical analysis
