Polymer Testing, 2020 Abstract The frictional behaviors of prepreg-prepreg and prepreg-tool play the most important role in hot diaphragm forming and greatly influence the quality of the final product. A new set-up was developed to characterize the frictional behaviors for unidirectional carbon fiber/epoxy prepreg.
