The effect of fiber orientation on fracture response of metallic fiber-reinforced adhesive thin films

The effect of fiber orientation on fracture response of metallic fiber-reinforced adhesive thin films

ABSTRACT: Incorporation of metallic fibers into the adhesive layer can significantly improve the mechanical behavior of the adhesive joint. This paper aims to assess the fracture behavior of an epoxy adhesive reinforced by longitudinal and lateral metallic fibers. Double cantilever beam (DCB) specim...
