Fibre-reinforced plastic composites - Determination of flexural properties - Amendment 1 (ISO 14125:1998/Amd 1:2011)

2010-09-27 EMA: Track changed according to ISO database: MINOR AMENDMENT!!!

Faserverstärkte Kunststoffe - Bestimmung der Biegeeigenschaften - Änderung 1 (ISO 14125:1998/Amd 1:2011)

Diese Internationale Norm legt ein Verfahren zur Ermittlung der Biegeeigenschaften von
faserverstärkten Kunststoffen nach dem Drei- und Vierpunkt-Verfahren (Verfahren A bzw. B) fest. Es werden
Norm-Probekörper festgelegt, jedoch sind die Parameter für andere Probekörpergrößen, falls angemessen,
enthalten. Für die Prüfgeschwindigkeiten wird ein Bereich angegeben.
1.2 Das Verfahren ist nicht zur Bestimmung von Design-Parametern geeignet, darf aber für die
Werkstoffprüfung oder als Prüfung bei der Qualitätskontrolle verwendet werden.
ANMERKUNG Der Biegemodul ist beispielsweise nur ein Näherungswert für den exakten, im einachsigen Zugversuch
ermittelten Elastizitätsmodul, da beim Biegeversuch keine Korrektur für die zusätzliche Durchbiegung durch
Scherbeanspruchung erfolgt, wodurch sich ein geringerer Wert für den Biegemodul ergibt, aber es sind
Prüfumfang/Probekörper-Dickenverhältnisse zu verwenden, die diese Auswirkung minimieren. Unterschiede zwischen
Zug- und Biegeeigenschaften werden auch durch die Materialstruktur und Materiallagerung verursacht.
˜1.3 Das Verfahren ist für faserverstärkte thermoplastische und duroplastische Kunststoffe geeignet.
ISO 178, Plastics — Determination of flexural properties, gilt für Pressmassen mit Fasern, die kürzer sind als
7,5 mm. Dies ist im Allgemeinen der Fall bei Materialien, die für das Spritzgießverfahren vorgesehen sind.™
1.4 Das Verfahren ist für Probekörper geeignet, die entweder direkt in den angegebenen Maßen geformt
werden, aus dem Mittelteil eines Norm-Vielzweckprobekörpers (siehe ISO 3167) oder aus halbfertigen oder
fertigen Produkten, z. B. aus Formteilen oder Schichtstoffen, ausgearbeitet werden.

Composites plastiques renforcés de fibres - Détermination des propriétés de flexion - Amendement 1 (ISO 14125:1998/Amd 1:2011)

Z vlakni ojačeni kompozitni polimerni materiali - Ugotavljanje upogibnih lastnosti - Dopolnilo 1 (ISO 14125:1998/Amd 1:2011)

1.1 Ta mednarodni standard opisuje metode za ugotavljanje upogibnih lastnosti z vlakni ojačanih kompozitnih polimernih materialov pri tritočkovni (metoda A) in štiritočkovni (metoda B) obremenitvi. Standardni preskusni vzorci so določeni, vendar so dodani parametri za druge velikosti vzorca za uporabo po potrebi. Vključen je nabor preskusnih hitrosti.
1.2 Metoda ni primerna za ugotavljanje parametrov zasnove, lahko pa se uporabi za presajanje materialov ali kot preskus za nadzor kakovosti. OPOMBA – Upogibni modul je na primer le primerna vrednost nateznega Youngovega modula elastičnosti, saj preskus ni namenjen dodatnim upogibom zaradi strižne napetosti, kar vodi do nižjih vrednosti upogibnega modula, ampak uporablja razmerja med preskusnim razponom/debelino preskušanca, ki minimizirajo ta učinek. Razlike med nateznimi in upogibalnimi lastnostmi povzroča tudi zgradba oz. plasti materiala.
1.3 Metoda je primerna za z vlakni ojačane plastomerne in duromerne kompozitne polimerne materiale. Neojačani polimerni materiali, polimerni materiali, napolnjeni z delci, in polimerni materiali, ojačani s kratkimi vlakni (t.j. krajši od 1 mm) so zajeti v standardu ISO 178.
1.4 Metode se uporabljajo na preskušancih, ki so lahko oblikovani, da se dosežejo želene dimenzije, s strojno obdelanim osrednjim delom standardnega večnamenskega preskusnega preskušanca (glejte ISO 3167) ali strojno obdelani iz polizdelkov ali končnih izdelkov, kot so oblikovanci ali laminati.
1.5 Metoda določa prednostne dimenzije preskusnih vzorcev. Preskusi, ki se opravljajo na preskušancih drugih velikosti ali na preskušancih, ki so pripravljeni pod drugačnimi pogoji, lahko dajo rezultate, ki niso primerljivi. Na rezultate lahko vplivajo tudi drugi dejavniki, kot sta hitrost preskušanja in priprava preskušancev. Rezultati za materiale z nehomogenim prerezom ali materiale, ki so nehomogeni nad delom linearnega elastičnega odziva, veljajo le za preskušeno debelino in zgradbo. Če so potrebni primerjalni podatki, je potrebno te dejavnike natančno nadzirati in zabeležiti.

Fibre-reinforced plastic composites - Determination of compressive properties in the in-plane direction (ISO 14126:2023)
SIST EN ISO 14126:2023

1.1 This document specifies methods for determining the compressive properties, in directions
parallel to the plane of lamination, of fibre-reinforced plastic composites, based on thermosetting or
thermoplastic matrices. The compressive properties are of interest for specifications and qualitycontrol
purposes. The test specimens are machined from a flat test plate, or from suitable finished or
semi-finished products.
1.2 Two loading methods and two types of specimen are described.
The loading methods are:
— Method 1: provides shear loading of the specimen (gauge length unsupported)
— Method 2: provides combined loading of the specimen (gauge length unsupported)
NOTE For tabbed specimens loaded using method 2, load is transferred through a combination of endloading
and shear-loading through the tabs.
The specimen designs are:
— Type A specimen: rectangular cross-section, fixed thickness, end-tabbed (mainly for aerospace
style preimpregnates (~ 0,125 mm ply thickness)
— Type B specimen: rectangular cross-section, range of thicknesses, untabbed or end-tabbed, two
specimen sizes are available (B1 and B2).
The Type A specimen is used for unidirectionally or biaxially reinforced materials tested in the
fibre direction, where the fibres are normally either aligned continuous or aligned long (>7,5 mm)
discontinuous. The Type B1 and B2 specimens are used for multi-directional aligned; mat, fabric and
other multi-directionally reinforced materials where the fibre structure is more complex and/or
coarser.
1.3 This document gives criteria for checking that the combination of test method and specimen
design result in valid failures. It is noted that alternative test method/specimen combinations will not
necessarily give the same result.
1.4 The methods specify required dimensions for the specimen. Tests carried out on specimens of
other dimensions, or on specimens that are prepared under different conditions, can produce results
that are not comparable. Other factors, such as the speed of testing, the support fixture used and the
conditioning of the specimens, can influence the results.

Fibre-reinforced plastics - Moulding compounds and prepregs - Determination of mass per unit area and fibre mass per unit area (ISO 10352:2020)
SIST EN ISO 10352:2020

This document specifies a method for the determination of the mass per unit area. It also specifies five methods (Method A to Method E) for the determination of the fibre mass per unit area of moulding compounds and prepregs. The five methods are as follows:
—     Method A: Extraction by Soxhlet;
—     Method B: Extraction by immersion in solvent in a beaker;
—     Method C: Decomposition by loss ignition;
—     Method D: Extraction by wet combustion;
—     Method E: Method by calculation.
This document is applicable to the following types of materials:
—     moulding compound and preimpregnated unidirectional sheet, tape, fabric and mats;
—     prepregs in which any type of reinforcement (aramid, carbon, glass, etc.) and any type of matrix (thermosetting or thermoplastic) has been used.
Typically, reinforcement fibres are coated with sizing or finishes. These normally dissolve with the resin and are, therefore, included in the resin content.
This document is not applicable to the following types of prepregs:
—     those containing reinforcements which are soluble (or partly soluble) in the solvents used to dissolve the resin.

Plastics - Acquisition and presentation of comparable single-point data - Part 2: Long-fibre-reinforced plastics (ISO 10350-2:2020)
SIST EN ISO 10350-2:2020

ISO 10350 identifies specific test procedures for the acquisition and presentation of comparable data for certain basic properties of plastics. In general, each property is specified by a single experimental value, although in certain cases properties are represented by two values obtained under different test conditions or along different directions in the material. The properties included are those presented conventionally in manufacturers' data sheets.
This document applies to reinforced thermoplastic and thermosetting materials where the reinforcement fibres are either discontinuous with a fibre length prior to processing greater than 7,5 mm or continuous (e.g. fabric, continuous-strand mat or unidirectional).
ISO 10350-1 deals specifically with unreinforced and filled plastics, including those using fibres less than 7,5 mm in length.
