ASTM D 6671 is used for determining the interlaminar fracture toughness of continuous fiber-reinforced composite materials. It can also be used in the adhesive joints testing. This test method is designed for use of composites consisting of unidirectional carbon fiber tape laminates with brittle and tough single-phase polymer matrices. An important feature of this test method and associated fixture is…
This test apparatus is useful to determine the opening Mode I interlaminar fracture toughness, GIc, of continuous fiber-reinforced composite materials by the double cantilever beam specimen. This test application is employable with composites consisting of unidirectional carbon fiber and glass fiber tape laminates with brittle and tough single-phase polymer matrices. Delamination phenomenon constitutes a strong weakness of many advanced laminated…
