Fibre-reinforced plastic composites - Shear test method using a shear frame for the determination of the in-plane shear stress/shear strain response and shear modulus (ISO 20337:2018)

This document specifies a method using a shear test apparatus for measuring the in-plane shear stress/shear strain response, shear modulus and shear strength of continuous-fibre-reinforced plastic composite materials with fibre orientations of 0° and 0°/90°.
This method is applicable to thermoset and thermoplastic matrix laminates made from unidirectional layers/non-woven fabrics and/or fabrics including unidirectional fabrics, with the fibres oriented at 0° and 0°/90° to the specimen axis, where the lay-up is symmetrical and balanced about the specimen mid-plane.
The method is suitable for determining shear properties in both the linear and nonlinear load-deformation range even at shear strains greater than 5 %.
Short and long fibre-reinforced plastic composites can also be tested using this document.

Faserverstärkte Kunststoffe - Schubversuch mittels Schubrahmen zur Ermittlung der Schubspannungs-/Schubverformungskurve und des Schubmoduls in der Lagenebene (ISO 20337:2018)

Dieses Dokument legt ein Verfahren zur Bestimmung der Schubspannungs-Schubverformungs-Kurve, des Schubmoduls und der Schubfestigkeit von endlosfaserverstärkten Kunststoffen mit einer Faserorientierung in 0° bzw. 0°/90° mittels einer Schubprüfvorrichtung in der Lagenebene fest.
Das Verfahren ist anwendbar auf Laminate, die aus einer thermoplastischen oder duroplastischen Grund-masse und aus unidirektionalen Lagen/Gelegen und/oder Geweben einschließlich unidirektionaler Gewebe mit einer Faserorientierung in 0° bzw. 0°/90° zur Probekörperachse bestehen. Der Laminataufbau muss symmetrisch und ausgeglichen um die Mittelebene des Probekörpers gestaltet werden.
Das Verfahren ist für die Bestimmung der Schubeigenschaften sowohl im linearen als auch im nicht-linearen Last-Verformungs-Bereich bei Schubverformungen auch über 5 % geeignet.
In Anlehnung an dieses Dokument können auch kurz- und langfaserverstärkte Kunststoffe geprüft werden.

Composites plastiques renforcés de fibres - Méthode d'essai de cisaillement à l'aide d'un châssis de cisaillement pour la détermination de la contrainte de cisaillement /déformation au cisaillement dans le plan et du module de cisaillement (ISO 20337:2018)

Le présent document spécifie une méthode utilisant un appareillage d'essai de cisaillement pour mesurer la contrainte de cisaillement/déformation au cisaillement dans le plan, le module de cisaillement et la résistance au cisaillement des matériaux composites plastiques renforcés de fibres continues avec une orientation des fibres de 0° et 0°/90°.
Cette méthode est applicable aux stratifiés à matrice thermodurcie et thermoplastique constitués de couches unidirectionnelles/non-tissés et/ou tissus, y compris tissus unidirectionnels, avec les fibres orientées à 0° et 0°/90° par rapport à l'axe de l'éprouvette, dans lesquels l'assemblage est symétrique et équilibré par rapport au plan médian de l'éprouvette.
Cette méthode convient pour déterminer les propriétés de cisaillement à la fois dans la plage de déformation de la charge linéaire et non linéaire, même à des déformations au cisaillement supérieures à 5 %.
Les composites plastiques renforcés de fibres courtes et longues peuvent également être soumis à l'essai selon le présent document.

Z vlakni ojačeni kompozitni polimerni materiali - Metoda strižnega preskusa z uporabo strižnega okvira za ugotavljanje odziva na ravninsko strižno/natezno obremenitev in strižnega modula (ISO 20337:2018)

Ta dokument določa metodo strižnega preskusa z uporabo strižnega okvira za ugotavljanje odziva na ravninsko strižno/natezno obremenitev, strižnega modula in strižne trdnosti z vlakni ojačenih kompozitnih polimernih materialov z usmerjenostjo vlaken 0 ° in 0 °/90 °.
Metoda je uporabna za termoreaktivne in plastomerne matrične laminate, izdelane iz enosmernih slojev/netkanih tkanin in/ali tkanin z enosmernimi vlakni, usmerjenimi 0 ° in 0 °/90 ° na os vzorca, kjer je postavitev simetrična in uravnotežena glede na srednjo ravnino vzorca. Metoda je primerna za določanje strižnih lastnosti v linearnem in nelinearnem razponu deformacije pri obremenitvi, tudi pri strižnih deformacijah, večjih od 5 %. S pomočjo tega dokumenta je mogoče preskusiti tudi s kratkimi in dolgimi vlakni ojačene kompozitne materiale.

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).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
