Improvement of the interlaminar fracture toughness of composite laminates by whisker reinforced interlamination

In this study, an attempt is made to improve the interlaminar fracture toughness of composite laminates by distributing whiskers along the interface of composite laminates during the lay-up process. Commercially available T800H/3631 CFRP prepreg and β-SiC whisker are employed to prepare the specimens. A simple spray method is developed to distribute whiskers on the prepreg. Unidirectional laminates of 24 plies with whisker reinforced...
