AB This study focuses on modeling the low-velocity impact behaviour of textile-shaped composites. Textile preforms are modeled using Texgen software. Six types of fabrics are considered: Twill (2/2) [0]4, twill (2/2) sequence [0/30/-30/0], twill (2/2) sequence [0/45/-45/0], and plain weave [0]4, plain weave sequence [0/30/-30/0], plain weave sequence [0/45/-45/0]. For the study of fabric damage under impact, the commercial finite element software Ls-dyna is used in transient regime. The "automatic-surface to-surface" approach is employed to model the contact between the impactor and the laminate, while the contact between fibres and the matrix is modeled using the "contact automatic surface to surface tiebreak" technique. Results from the modeling are graphically represented over the impact time. With increasing impact velocity, the contact force, displacement at the impact point, and impact energy increase accordingly.
