Abstract
Deepdrawing experiments are performed on doublelayered laminates consisting of glass/PP woven fabrics The forming of woven composites is often accompanied by unwanted wrinkles and springback By using a fractional factorial experimental design the influence of preheating temperature deepdrawing velocity blankholder pressure mould temperature and interlayer thickness on wrinkling and springback are assessed The parameter values that result in an optimal quality of shape are determined The effects are explained by linking them to the interply shear behaviour and the change in temperature during deepdrawing It can be concluded that a high preheat temperature a high deepdrawing speed a medium blank holder pressure a low tool temperature and the addition of extra polypropylene between the layers leads to a wrinkle free and fully formed composite
