Rapid manufacturing of composite structures made of fabric flax / polypropylene
One of the major challenges of composites based on a thermoplastic matrix is to fabricate finished parts both in a single processing step and reduced time production. For this purpose, a stamping airflow device is here developed. It permits to produce the V-shaped composite parts made of a comingled flax / polypropylene fabrics only in a few minutes. This is particularly attractive to automotive production. First, preliminary tests and an optimization set of processing parameters are performed. Then, an assessment of the new technical manufacturing reliability of composites compared to mechanical properties of material prepared by a traditional thermo-compression process is presented.

DERBALI, Imed; TEREKHINA, Svetlana; GUILLAUMAT, Laurent; OUAGNE, Pierre (Springer Science and Business Media LLC, 2018)The use of natural fibre reinforced composites such as flax fibre / polypropylene is in a constant expansion particularly in automotive and marine industries due to their good mechanical properties, low density and thus, ...
CROZATIER, Mathilde; TEREKHINA, Svetlana; DAU, Frédéric; GUILLAUMAT, Laurent (2016)Mechanical behavior of composite laminates depends strongly on the manufacturing process. It is necessary to use representative samples of the material, and therefore of the process. In the case of filament winding, specimens ...
Analytical and numerical study based on experimental investigation of different curved sandwich composites manufactured by filament winding process HADDAD, Mohamed; GUILLAUMAT, Laurent; TEREKHINA, Svetlana; CROZATIER, Mathilde (Sage, 2018)Sandwich structures, due to their high stiffness versus lightness ratio, are used progressively in high performance products. In order to design these structures with the most appropriate dimensions and material combinations, ...
