1.1 This International Standard specifies a method for the determination of mode I interlaminar fracture
toughness (critical energy release rate), GIC, of unidirectional fibre-reinforced plastic composites using a double
cantilever beam (DCB) specimen.
1.2 It is applicable to carbon-fibre-reinforced and glass-fibre-reinforced thermosets and thermoplastics.
