Plastics - Determination of tensile properties - Part 5: Test conditions for unidirectional fibre-reinforced plastic composites (ISO 527-5:2021)

This document specifies the test conditions for the determination of the tensile properties of unidirectional fibre-reinforced plastic composites, based upon the general principles given in ISO 527-1.
NOTE      Isotropic and orthotropic reinforced materials are covered by ISO 527-4.
The methods are used to investigate the tensile behaviour of the test specimens and for determining the tensile strength, tensile modulus, Poisson's ratios and other aspects of the tensile stress-strain relationship under the conditions defined.
The test method is suitable for all polymer matrix systems reinforced with unidirectional fibres and which meet the requirements, including failure mode, set out in this document.
The method is suitable for composites with either thermoplastic or thermosetting matrices, including preimpregnated materials (prepregs). The reinforcements covered include carbon fibres, glass fibres, aramid fibres and other similar fibres. The reinforcement geometries covered include unidirectional (i.e. completely aligned) fibres and rovings and unidirectional fabrics and tapes.
The method is not normally suitable for multidirectional materials composed of several unidirectional layers at different angles (see ISO 527-4).

Kunststoffe - Bestimmung der Zugeigenschaften - Teil 5: Prüfbedingungen für unidirektional faserverstärkte Kunststoffverbundwerkstoffe (ISO 527-5:2021)

Dieses Dokument legt auf der Basis der allgemeinen Grundsätze aus ISO 527 1 die Prüfbedingungen für die Bestimmung der Zugeigenschaften unidirektional faserverstärkter Kunststoffverbundwerkstoffe fest.
ANMERKUNG   Isotrop und anisotrop verstärkte Werkstoffe werden von ISO 527 4 erfasst.
Die Verfahren werden verwendet, um das Zugverformungsverhalten von Probekörpern zu untersuchen und die Zugfestigkeit, den Zugmodul, die Poissonzahlen und andere Gesichtspunkte der Zugspannungs Dehnungs Beziehung unter den festgelegten Bedingungen zu ermitteln.
Das Prüfverfahren ist für alle unidirektional faserverstärkten Polymermatrixsysteme geeignet, die den in diesem Dokument angegebenen Anforderungen, einschließlich Ausfallart, entsprechen.
Das Verfahren ist geeignet für sowohl thermoplastische als auch duroplastische (wärmehärtbare) Verbundwerkstoffe, einschließlich vorimprägnierter Materialien (Prepregs). Die berücksichtigten Verstärkungen schließen Kohlenstofffasern, Glasfasern, Aramidfasern und andere ähnliche Fasern ein. Die berücksichtigten Verstärkungsgeometrien umfassen unidirektionale (d. h. vollständig ausgerichtete) Fasern und Rovings sowie unidirektionale Gewebe und Bänder.
Das Verfahren ist gewöhnlich nicht für multidirektionale Materialien geeignet, die aus mehreren unidirektionalen Schichten mit unterschiedlichen Winkeln bestehen (siehe ISO 527 4).

Plastiques - Détermination des propriétés en traction - Partie 5 : Conditions d'essai pour les composites plastiques renforcés de fibres unidirectionnelles (ISO 527-5:2021)

Le présent document spécifie les conditions d’essai pour la détermination des propriétés en traction des composites plastiques renforcés de fibres unidirectionnelles, basées sur les principes généraux établis dans l’ISO 527‑1.
NOTE       Les matériaux renforcés isotropes et orthotropes sont couverts par l’ISO 527‑4.
Les méthodes sont utilisées pour étudier le comportement en traction des éprouvettes et pour déterminer la résistance en traction, le module d’élasticité en traction, les coefficients de Poisson et d’autres aspects de la relation contrainte/déformation en traction dans les conditions définies.
La méthode d’essai convient à tous les systèmes de matrices polymères renforcées de fibres unidirectionnelles conformes aux exigences établies dans le présent document, y compris le mode de rupture.
La méthode convient à la fois aux composites à matrices thermoplastiques et thermodurcissables, y compris les matériaux préimprégnés (prepregs). Les renforts concernés comprennent les fibres de carbone, les fibres de verre, les fibres d’aramide et autres fibres similaires. La géométrie des renforts comprend les fibres ou stratifils unidirectionnels (c’est-à-dire parfaitement alignés) et les tissus et rubans unidirectionnels.
Normalement, la méthode ne convient pas aux matériaux multidirectionnels composés de plusieurs couches unidirectionnelles assemblées sous des angles différents (voir l’ISO 527-4).

Polimerni materiali - Ugotavljanje nateznih lastnosti - 5. del: Preskusni pogoji za enostransko z vlakni ojačene polimerne kompozite (ISO 527-5:2021)

Ta dokument določa preskusne pogoje za določanje nateznih lastnosti enostransko z vlakni ojačanih polimernih kompozitov na podlagi splošnih načel, opredeljenih v standardu ISO 527-1.
OPOMBA: Izotropno in ortotropno ojačani materiali so zajeti v standardu ISO 527-4.
Uporabljene so metode za preučevanje nateznih lastnosti preskušancev ter za ugotavljanje natezne trdnosti, nateznega modula, Poissonovega razmerja in drugih vidikov razmerja natezna napetost/deformacija pri določenih pogojih.
Preskusna metoda je primerna za vse polimerne matrične sisteme, enostransko ojačane z vlakni, ki izpolnjujejo zahteve, vključno z vrsto odpovedi, določeno v tem dokumentu.
Metoda je primerna za kompozite s termoplastičnimi ali termoreaktivnimi matricami, vključno s predhodno impregniranimi materiali. Zajete ojačitve vključujejo ogljikova vlakna, steklena vlakna, aramidna vlakna in druga podobna vlakna. Zajete geometrije ojačitve vključujejo enostranska (tj. popolnoma poravnana) vlakna in rovinge ter enostranske tkanine in trakove.
Metoda običajno ni primerna za večstranske materiale, sestavljene iz več enostranskih
plasti pod različnimi koti (glej ISO 527-4).

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
