Experimental investigation and finite element modelling of microstructural composite material
Résumé
Experimental investigations on PA6GF composite material through SEM images showed high microstructural variability. Local fibre volume fractions were quantified. The use of X-ray tomography techniques allowed examinations of matrix damage mechanisms by void growth. A constitutive model for bulk PA6 polymer was set up in order to simulate PA6 behavior submitted to complex triaxial loadings. Unit cell computations were then carried out to better understand the influence of hydrostatic pressure on composite materials.
