Composite Materials

The advantages of composite materials lie in their ability to combine lightness and strength, providing versatile and high-performance solutions for a variety of applications. Their adaptability allows them to specifically meet the requirements of different industries, ranging from aerospace to automotive, while offering properties such as corrosion resistance.

The design of composite structures is not trivial. Many parameters and phenomena must be taken into account: the number of plies, their shapes, orientations, and the order of their stacking, as well as the specific behavior of such materials and the potential instabilities associated with them: buckling, post-buckling, as well as damage within plies or between them (delamination). This design process is based on a succession of steps represented here.

GDTech offers comprehensive studies at all levels of the pyramid, integrating virtual and physical tests based on CAD and CAE. Our services include drafting test specifications, tool design, instrumentation definition, test monitoring, and correlation between tests and simulations. We also excel in automated finite element model adjustment and integration of nonlinear components.
