3D Printing
less than 1 minute read
4D printing extends additive manufacturing by designing structures that transform over time in response to external stimuli — heat, light, moisture, or mechanical loading. When applied to composite materials, this opens the door to programmable structural elements that can reconfigure themselves without motors or ac...

Stereolithography (SLA) and masked SLA (MSLA) are powerful photopolymer additive manufacturing techniques known for their high resolution and smooth surface finish. However, commercially available systems are almost exclusively single-resin: one material per print. This limits the ability to produce graded structure...

High-performance thermoplastic composites — particularly carbon fiber reinforced PEEK and PEKK — are increasingly used in aerospace applications due to their excellent mechanical properties and processability. However, manufacturing scrap and end-of-life parts represent a significant waste stream that currently lack...

One of the grand challenges of space exploration is manufacturing structural components on-site, rather than transporting everything from Earth. The Moon offers a potential source of raw materials — lunar regolith — that could be combined with polymers to produce functional composite parts using additive manufacturi...

A lightweight 3D printed structure after tensile failure
The blimp or zeppelin is an aircraft, also called aerostat (shown in the figure below[^1] ), that has the essential characteristic of being lighter-than-air. Airship technologies have known a golden age in the early twentieth century followed by a sudden d...

Full field characterization
4 minute read
Digital Image Correlation (DIC) is a 2D or 3D (stereo-DIC) optical method that allows for the measurement of the displacement field between two camera images. These images contain a speckle pattern that is disposed (painted, deposited, etched,…) on the surface of the specimen that will be studied.
It is usually ma...

First phase of the project
The first phase of this project was carried out by Bénédicte Bonnet (now a happy Msc in biomedical engineering) and mainly aimed at developing an experimental setup that can be used to quantify and better understand the presence of air leaks in lungs after resection. The study was supervi...

“Complex” (composite) materials
The profitability of the aerospace, automotive, energy and many other industries is strongly linked to a reduction in the energy footprint and mass of the structures involved, while maintaining a similar level of performance and safety. To achieve these objectives, composite material...

Carbon fiber reinforced thermoplastic composites (CF/PPS, CF/PEI, CF/PEEK) are prime candidates for next-generation aerospace structures thanks to their high specific stiffness, chemical resistance, and weldability. However, understanding their long-term durability under realistic service conditions — thermal cyclin...

Space debris is a growing threat to operational satellites and future space missions. One passive deorbitation strategy uses electromagnetic drag sails: large, lightweight deployable panels that interact with Earth’s magnetic field to produce a braking force, gradually lowering a satellite’s orbit until atmospheric ...
