Master Thesis 30 hp: Repair methods of composite radome structures

Göteborg, Sweden
Closing date: 30 November 2022

Your future challenge

Modern sensors are placed behind structures, often designed in composite materials. These structures severe several different purposes and are therefore required to be multifunctional.

The most important properties are electrical properties, structural properties and environmental protection. Many products are used in harsh environments around the world, with high demands on accessibility. Being able to repair these while maintaining performance is of great importance. 

The products referred to in this project are radomes constructed as sandwich structures with high demands for radar permeability. Many repair methods and materials are based on repairs of a structural nature and are not always suitable from the perspective of other properties.

The purpose of the project is to describe repair methods that meet the requirements of multifunctional radomes. These repair methods need to be general for some typical damages, and they must be able to be performed with materials that are available around the world.

The work includes studies of materials, repair methods and structural properties of repaired radomes.

Your profile

We are looking for two students studying mechanical engineering or equivalent, preferably within construction/design, materials engineering or structural analysis. Previous experience and knowledge in composites, composite manufacturing, mechanical design and analysis is a merit. Two students working together with the thesis is recommended but not a requirement.

This position requires that you pass a security vetting based on the current regulations around/of security protection. For positions requiring security clearance additional obligations on citizenship may apply.
