Portfolio Composite

Designed and optimized composite tooling to improve efficiency, safety, and part quality.

Performed surface analysis and defined acceptance criteria aligned with automotive interior requirements.

Contributed to reporting and validation processes for composite components.

Numerical simulation of temperature changes in polymers exposed to cycles of pressurisation and depressurisation with hydrogen gas for storage and distribution applications

Gas decompression phases are particularly damaging to polymeric materials; as they can lead to the nucleation and growth of multiple voids and/or cracks. This; phenomenon results from the local expansion of previously absorbed gas, when desorption from the; polymer is too slow relative to the imposed decompression. This mode of damage is likely to affect the mechanical properties of the polymer component and its permeability, particularly when use leads to repeated decompressions.

Support for keyboard. The plasticity of the materials allow the etention of the keyboard and keep it safe from falling.

Thermocompression : Composite part has been made by thermo compression. The purpose here was to insurure that the toolgap allow the same thickness all along the part.

Prepreg: Composite part has been made by layering prepreg layer.
The part has been put in a vaccum bag after each layer has been applied.

Infusion Composite part has been made by infusion process.
A special coating has been applied on the outter side in order to make the part fully water proof.

Thermocompression : Composite part has been made by thermo compression. The purpose here was to insurure that the toolgap allow the same thickness all along the part.

Composite guitar core: The core will be made y layering carbon fabric. Composite part has been made by layering prepreg layer.
Firstly, a foam templete is made. The important part is to make sure the draft angle will allow a proper demolding.
Once it is done, e can manufacture the mold by applying fiber glass (after applying a special mold gelcoat allowing a good surface).
The mold has to be as stiff as possible to ensure the the good geometry of the part.
The core is made by infusion. The cure must be at room temperature.
