Composite materials allows manufacturing structures with high mechanical properties at low mass. Consequently they are a possible way to reduce energy consumption in transportation. Their development is important in particular for civil planes. In automotive industries many projects aims to use composite materials in future cars. In civil engineering, composite materials are used to repair and reinforce buildings.
Composite materials are available in many form and produced using a variety of manufacturing processes. The manufacturing processes are essential for the quality of the final composite. These processes are numerous and often complex.
Manufacturing simulation enables an initial validation of the process and the determination of suitable process parameters. This can prevent a time consuming and expensive "trial and error" process design. Furthermore, the fibre reorientation due to forming is predictable, which can be used as input value for structural analysis. Difference in properties of a composite and structural response of a composite part “as manufactured”, in comparison with “as designed”, are getting in a focus of industrial research.
The simulation of composite manufacturing processes needs the knowledge, the experimental analysis, and the modelling of the physical phenomena involved. During the process, these phenomena concern materials in large deformation (depending on temperature, phase change….). The experimental analysis, modelling and the simulation of physical phenomena during composite forming are the objectives of the colloquium.
The conference will focus on composite materials with continuous fibres for structural parts The forming of the reinforcement without resin (dry preform) and with non-hardened resin (prepreg) will be considered. This leads to two main scientific topics: forming of fibrous material (often call draping) and thermomechanics and consolidation of the composite in prepreg forming.

The colloquium will be organized and supported by a French research group affiliated to CNRS (National Center for Scientific Research), entitled “GDR 3671 Mise en oeuvre des matériaux composites”) and supported by a European scientific association, ESAFORM (European association for material forming).
The proposed EUROMECH Colloquium will be a proper meeting point to establish a state of art and to exchange the different approaches aimed at tackling tough problems related to the mechanics of composites materials at various scales during manufacturing.
