Abstract [en]

Traditionally components made from prepreg materials are laid up by hand, this is labor intense and thus expensive. An alternative is to lay up a prepreg stack using an ATL machine and then use drape forming to form this stack. To predict how this stack deforms it is important to know how it behaves during forming. Important parameters are friction between prepreg layers as well as well as the friction between the prepreg and the tool. For this thesis experiments were performed to obtain friction data between the tool and prepreg surfaces. This data showed that this friction is about 20-50% of the friction ompared to the friction between prepreg layers. Based on this data friction models adopted for software implementation were designed; these models were also implemented in the FEM software AniFrom.
