Aerospace series - Fibre reinforced plastics - Test method - Determination of in-plane shear properties (± 45° tensile test)
This European Standard specifies the procedure for the determination of the in-plane shear strength
and modulus of fibre composites. The procedure is based on the uni-axial tensile stress-strain response
of a ± 45° laminate which is symmetrically laminated about the mid-plane.
This standard is applicable to composite laminates manufactured from unidirectional tape or woven
fabric reinforcement.
This standard does not give any directions necessary to meet the health and safety requirements. It is
the responsibility of the user of this standard to consult and establish appropriate health and safety
precautions.

Diese Norm legt das Verfahren zur Bestimmung der Schubfestigkeit in der Lagenebene und des Schubmoduls von Verbundwerkstoffen fest. Das Verfahren basiert auf dem einachsigen Spannungs-Dehnungs-Verhalten eines ± 45° Laminats, das symmetrisch um die Mittelebene laminiert ist.
Diese Norm gilt für aus gleichgerichteten Schichten oder Gewebeverstärkung gefertigte Verbundwerkstoffe.
Diese Norm legt keine Anleitung fest, die für das Einhalten der Gesundheits- und Sicherheitsvorschriften erforderlich ist. Es liegt in der Verantwortung des Anwenders dieser Norm, die entsprechenden Gesundheits- und Sicherheitsvorkehrungen zu treffen.

Aeronavtika - Z vlakni ojačeni polimerni materiali - Preskusna metoda - Ugotavljanje nateznih lastnosti (natezni preskus pri ±45°)
Ta evropski standard določa postopek za ugotavljanje nateznih lastnosti in modulov vlaknatih kompozitov. Postopek temelji na enoosnem nateznem napetostno-deformacijskem odzivu laminata pri ± 45°, simetrično laminiranega okrog srednje plošče.
Ta standard se uporablja za kompozitne laminate, proizvedene iz enosmernega traku ali z vlakni ojačenih materialov.
Ta standard ne vsebuje nobenih smernic, potrebnih za izpolnjevanje zdravstvenih in varnostnih zahtev. Uporabnik tega standarda se mora posvetovati in določiti ustrezne zdravstvene in varnostne ukrepe.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
tensile stress at a given moment during the test
longitudinal tensile load experienced by the test specimen at a particular moment during the test,
divided by the initial unit cross sectional area within the gauge length
3.2
shear stress at a given moment during the test
the shear stress is defined as the in-plane shear stress with its principal direction under ± 45° with the
direction in which the tension load is applied, and its magnitude is half of the tensile stress
3.3
shear strength
the shear strength is the maximum occurring shear stress during the test. For calculation see 9.1.

Experimental test data from a tensile test are used for generating the shear strength and modulus. 5 Designation of the method The designation of the used method shall be drawn up according to the following example.
