Internship | MSc Thesis Ballistic protection improvement via substrate surface treatment

The performance of the adhesive layer (bond line) in a ceramic multi-layer armour system is a critical component in determining single- and multi-hit ballistic protection. Adhesive layer research in ballistic armour is limited, especially when considering the impact of substrate surface (pre)treatment on ballistic performance. Not only are the cleaning/degreasing steps critical in adhesive/ballistic performance, but controlled surface modifications can also improve the armour stopping power. These modifications take the form of chemical (e.g., laser treated, re-firing, or silane treatment) or morphological (e.g., laser treatment, nanostructuring, or grit blasting) treatments which improve bonding strength and ballistic protection of the system.

The impact of these surface pretreatment processes on ballistic protection is not fully understood and has yet to be explored for current adhesives utilised in multi-layer armour systems. This project will investigate, in collaboration and under guidance from TNO, the optimal surface preparation techniques for adhesive bonding of a ceramic front plate (silicon carbide) to a backing plate (fibre-glass composite and steel), for adhesives currently utilised in armour systems. The adhesive bond strength will be carefully characterised before ballistic performance characterisation at TNO state-of-the-art ballistic test facilities.

You are in the final stages of your masters degree in physics, mechanical engineering or a similar degree and have some track record in the field of material science, surface manipulation/characterisation or adhesive bond lines. You have experience in conducting experimental research and are focused on conducting reproducible research. The ability to communicate your research internally and externally is valued.

You want an internship opportunity on the precursor of your career; an internship gives you an opportunity to take a good look at your prospective future employer. TNO goes a step further. It’s not just looking that interests us; you and your knowledge are essential to our innovation. That’s why we attach a great deal of value to your personal and professional development.

After the first CV selection, the application process will be conducted by the concerning department. TNO will provide a suitable internship agreement. If you have any questions about this vacancy, you can contact the contact person mentioned below.

For this internship vacancy it is required that the AIVD issues a security clearance (VGB) after conducting a security screening. Take into account that this process may take about 8 weeks. If you have been abroad for more than 6 consecutive months, or if you do not have the Dutch nationality, it may take longer. Read more about security screening on the AIVD website.

Important to be aware of before applying:

• Before the start of the internship, the internship agreement from TNO needs to be signed. For students at a college or university based in the Netherlands, TNO uses the UNL-template (supplemented with a number of specific agreements from TNO). For students of foreign and MBO educational institutions, the TNO internship agreement applies. TNO does not sign any other internship agreements.
• Before the start of the internship, the educational institution will need to confirm in writing that:
  • 1) you are enrolled at the educational institution during the internship, and;
  • 2) the internship takes place as part of the programme of the study.
• The confirmation of educational institution takes place by signing the UNL template or forms prepared by TNO.
• Interns at TNO must be in possession of a Dutch residential address at the start of the internship. Performance of internship activities from abroad is not possible.
