Mechanical characterisation of the shear, bending and friction behaviour of bindered woven fabrics during the forming process

A critical process step within the liquid composite moulding constitutes in the preforming of two-dimensional textile material into a near-net-shape and load-capable fibre structure by stamp forming. This paper presents fundamental material experiments on the shearing behaviour, bending properties and friction behaviour considering the binder quantity and forming temperature. In addition, the influence of the process time on the resulting stability of the preform is examined. The findings indicate that the quantity of the binder as well as the forming temperature and the process time have a great influence on the preform quality.
