Scientific report
Scientific report
Among the various lightweight materials, composites appear as very promising materials and their development have attracted more and more attention in the transportation. The aviation industry was the first to introduce composite materials to replace conventional materials such as aluminium. As an example, the amount of composite materials in airplane has raised to 53% in the Airbus A350. However, the properties of composite materials are not well reported because they are a complex class of materials exhibiting highly anisotropic behavior. They must be then fully characterized as it was done for conventional materials (e.g. aluminum, titanium …). Moreover, it is obvious that the methods developed for metals are not applicable for the composites.
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 analyses.
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 and in particular the mechanics concern materials in large deformation (depending on temperature, phase change….). The experimental analysis, modelling and the simulation of physical phenomena during composite forming have been the objectives of the colloquium.
The conference have concern principally the composites with continuous fibres for structural parts and a large number of processes:
Thermoset and thermoplastic prepreg forming, LCM processes (Liquid Composite Moulding), RTM processes, infusion.
The proposed EUROMECH Colloquium 602 was an opportunity 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.
Topics of the Colloquium:
1. Draping of fibrous preforms and prepregs.
Forming of a continuous fiber reinforcements leads to specific mechanical problems because the mechanical behavior of these reinforcements is specific in view of the possible relative slippage between the fibers and because of the quasi-inextensibility of the fibers. The following topics have been discussed: Mechanical tests for fibrous reinforcements (in plane and transverse shear, biaxial tension, bending, transverse compaction, constitutive law for textile reinforcements (Hyper elasticity, hyper viscoelasticity…), Simulations of preform deformation at macro, meso and microscale, specific finite elements, locking of textile materials, full field strain measurements (DIC) and Micro CT analyses of internal geometry, generalized continuum mechanics for textile materials. Second gradient approaches
2. Thermo mechanics, Thermo kinetics and Couplings
Composite forming processes are generally carried out at high temperature and the coupling between mechanical and thermal temperature is important. The consolidation and crystallization of the resin are also coupled with the forming deformation. The following topics have been discussed: Multi-scale and multi-physical models and algorithms, Curing, crystallization, polymerization, Coupling algorithmic, Advanced calculation strategies in couplings (reduction of models, ...)
After the colloquium:
• A group of participants are in contact with the CISM International Centre for Mechanical Sciences (Udine), to offer a course on composite forming
• About twenty participants sent an extended version of their contribution to the journal Composites part A for publication in a virtual special issue on the subject of the colloquium
