Optimisation des paramètres d'estampage de renforts secs pour applications composites structuraux (original) (raw)

RTM processes type can be used for manufacturing high performance composite materials with a high production rate and guaranteed the manufacturing repeatability. Usually, this kind of process is decomposed in two steps: Shaping the fibrous reinforcements (preforming) Injection of the resin (or impregnation) in the preform. One of the shaping process envisaged by the high-volume industry is stamping. However, to shape a complex part with a large size, the “traditional” way shows limits, so complementary developments and growing this process in maturity are needed. 23 ème Congrès Français de Mécanique Lille, 28 Août au 1 er Septembre 2017 2 In this paper, several steps of the research approach are presented: Material characterization (tensile, bend and shear): the bending and shear characterization tests are simulated on PAM FORM (ESI GROUP). Stamping of elementary geometry (hemisphere): the correlation experiments / simulation permit to adjust the numeric material law Application to ...
