DUQUEINE Group - Aerospace R&D

Contribute to developing a high-rate manufacturing process for thermoplastic carbon-fibre aerospace parts by studying the relationship between process settings, part quality and cycle time.

I first measured and analysed parts from an initial trial campaign. Based on the results, I contributed to adjusting the trial production line, then carried out a new manufacturing campaign with our external partner. I subsequently measured and analysed the new parts to assess the effects of the adjustments on their quality and geometry.

I compared dimensional measurements, visual observations, specialist inspection reports and thermal data to investigate possible causes of defects. Ultrasonic testing and 3D probing were also carried out to check compliance with the tolerances specified on the engineering drawing. I organised the findings into a defect–cause summary and a tracking document for process parameters and indicators. The work also included 3D scanning and CAD comparisons with Creaform MetraSCAN, as well as technical action tracking with our external partner.

I am also developing an initial AI-assisted tool to automate report preparation. The tool is still at an early stage.

This sequence of measurement, analysis, adjustment and manufacturing enabled us to assess how changes affected the parts produced. I am now helping prepare another trial campaign with new tooling, with the aim of achieving very high production rates. The performance of this new tooling will be assessed during the forthcoming trials.

Following my internship, I continued at DUQUEINE as an R&D Engineer. Alongside the process-development work, I took responsibility for tracking a metal 3D-printed mould project, monitoring milestones and contributing to design checks. I also manage the development of new small-scale prototype moulds for Cutoff.
