Finite element modeling of buckle defects formation during RTM preforming of dry woven reinforcements
Zakariae EL-ALAMI, Audrey HIVET, Gilles HIVET
Abstract. Mesoscopic defects, such as buckles and yarn sliding, arise in dry woven reinforcements during the preforming step of processes like the Resin Transfer Molding process. To study these defects, the LaMé laboratory developed an experimental device based on the Pullout test, which replicates the conditions leading to defect formation but does not fully explain the underlying mechanics. To address this, a Finite Element Model (FEM) is proposed to complement experimental data by providing detailed insights into stress, strain, and friction. While the model offers preliminary predictions of buckle defects, a full identification of the remaining parameters, including friction and those related to the fixed jaws, is essential for accurate parametric studies on their formation.
