This European Standard was approved by CEN on 10 August 2013.

CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this
European Standard the status of a national standard without any alteration. Up-to-date lists and bibliographical references
concerning such national standards may be obtained on application to the CEN-CENELEC Management Centre or to any CEN
member.
This European Standard exists in three official versions (English, French, German). A version in any other language made by
translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC Management
Centre has the same status as the official versions.

CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia,

identical text or by endorsement, at the latest by May 2016, and conflicting national standards shall be
withdrawn at the latest by May 2016.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent
rights.
According to the CEN-CENELEC Internal Regulations, the national standards organizations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria,
Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia,
France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta,
Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland,

1 Scope
This standard specifies the procedure to determine the mode II interlaminar fracture toughness energy
G of carbon fibre composites manufactured from unidirectional tape or woven fabric.
IIC
This standard does not give any directions necessary to meet health and safety requirements. It is the
responsibility of the user of this standard to consult and establish appropriate health and safety
precautions.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
interlaminar fracture toughness energy
the interlaminar fracture toughness energy is the energy per unit plate width which is necessary to
produce an unit crack growth at an interlaminar crack between two plies of a laminate
3.2
mode II
the mode indicates the method by which the load is applied to produce the crack. Mode Il crack extends
as a result of shear forces at the crack tip introduced by a flexural test
3.3
G
IIC
G is the designation of the interlaminar fracture toughness energy determined by a mode II
