Composite materials

Materials development and industrialization: new and improved processes and products
Composite materials

Organic matrix composite materials can be defined as a combination of fibrous reinforcements and polymer matrix. Through their properties (good mechanical performances, low density, resistance to corrosion, etc.), these materials help meet today’s societal issues and challenges.

IRT M2P’s composite materials activity was initially structured around high speed processes and the consideration of environmental impacts.

We are now also able to offer a global technological «materials, processes and products» approach adapted to various sectors and markets.

Development and high-volume production of hybrid preforms (multi-material and multistructure)
Preceding step of injection molding or consolidation, preforming can be done with dry materials or prepreg materials Injection

Molding processes
Adapted to thermosets and thermoplastics, RTM or C-RTM processes are mainly used for complex geometries or high-end applications

Compression molding (SMC, BMC)
Pressing semi-finished products to produce high-volume complex parts

Composite materials

Continuous process for manufacturing composite sections (which can be hollow bodies)
IRT M2P focuses, among other things, on the development of materials, processes and products related to thermoplastic pultrusion

Composite materials

Automated Fiber Placement (AFP)
Sometimes associated with additive manufacturing, this process uses successive draping operations to achieve blanks or 3D parts

Out of autoclave (OoA) thermoforming and consolidation
The shaping and consolidation of thermoplastic materials is a crucial step that confers thermomechanical properties

Manual processes, characterization, and laboratory
Lightweight processes (such as infusion) are widely used for prototyping and manufacturing «small» series of large parts. Coupled with a laboratory environment and characterization, this is an economically attractive and rapid means of implementation

Use and development of models and software for process simulation and mechanical design of products
