ASTM D6671 determines interlaminar fracture toughness, Gc, of continuous fiber-reinforced composite materials at various Mode I to Mode II loading ratios using the Mixed-Mode Bending (MMB) Test. Susceptibility to delamination is one of the major weaknesses of many advanced laminated composite structures. ASTM D6671 provides knowledge of the interlaminar fracture resistance of composites which is useful for product development and material selection.
