Abstract: The success or failure of composite formation is determined by the properties of a material that predominate deformation during the process. Wrinkling is caused by out-of-plane deformation due to compressive loading in the plane of the material during the forming process. Consequently, capturing the out-of-plane properties using a suitable experimental method is required with the ultimate aim of predicting and optimizing forming processes. A comparison between two test methods to characterize the bending behavior of woven fabric prepreg was presented. Results show that the vertical cantilever test offers a good control of the deflection shape and reproducible results. On the contrary, the sample twisting was observed during the horizontal test as the sample is bent under its own weight.
