Fibre-reinforced plastic composites - Declaration of raw material characteristics - Part 4: Specific requirements for fabrics

This part of this European Standard specifies the minimum information to be declared for fabrics to be used for the manufacturing of composites products, also impregnated products, but not to the composite products or impregnated products themselves.
These specific declaration requirements are in addition to the general requirements given in Part 1 of this standard (i.e. EN 16245-1).
This document includes requirements for the Certificate of Analysis (CoA). The purpose of the CoA is to verify that material properties and quality conform to the declared values.
This part of the standard is applicable to uni-axial and multi-axial fabric material.

Faserverstärkte Verbundwerkstoffe - Angabe von Werkstoffeigenschaften - Teil 4: Spezifische Anforderungen an Gewebe

Dieser Teil der Europäischen Norm legt die Mindestangaben für Gewebe fest, die zur Herstellung von Produkten aus Verbundwerkstoffen und auch aus getränkten Werkstoffen verwendet werden. Die Festlegungen gelten nicht für diese Produkte selbst.
Diese spezifischen Anforderungen an die Deklaration ergänzen die in Teil 1 dieser Norm (d. h. EN 16245 1) angegebenen allgemeinen Anforderungen.
Dieses Dokument enthält Anforderungen an das Analysenzertifikat (en: CoA = Certificate of Analysis). Zweck des CoA ist es zu verifizieren, dass die Werkstoffeigenschaften und die Qualität den angegebenen Werten entsprechen.
Dieser Teil der Norm gilt für uniaxiale und multiaxiale Gewebe.

Composites plastiques renforcés de fibres - Déclaration des caractéristiques des matières premières - Partie 4: Exigences particulières pour les tissus

La présente partie de cette Norme Européenne spécifie les informations minimales devant être déclarées pour les tissus destinés à être utilisés pour la fabrication de produits en composites, et de produits imprégnés mais pas les produits composites et les produits imprégnés eux-mêmes.
Ces exigences particulières de déclaration viennent en complément des exigences générales de la Partie 1 de la présente norme (à savoir l’ EN 16245 1).
Le présent document contient les exigences relatives au certificat d'analyse (CA). Le CA a pour but de confirmer que les propriétés et la qualité des matériaux sont conformes aux valeurs déclarées.
La présente partie de la norme est applicable aux matériaux à base de tissus uni axiaux et multi axiaux.

Z vlakni ojačeni kompozitni polimerni materiali - Navajanje karakteristik surovin - 4. del: Posebne zahteve za tkanine

Ta del tega evropskega standarda določa minimalne informacije, k morajo biti navedene za tkanine, ki se uporabljajo za izdelavo kompozitnih izdelkov in impregniranih izdelkov, vendar pa ne velja za kompozitne ali impregnirane izdelke same. Te posebne zahteve za navajanje so dodatek splošnim zahtevam, podanim v 1. delu tega standarda (npr. EN 16245-1). Ta dokument vključuje zahteve za potrdilo o analizi (CoA). Namen potrdila o analizi je overitev, da so lastnosti materialov in kakovost skladni z deklariranimi vrednostmi. Ta del standarda se uporablja za enoosne in večosne tkanine.

Overview

EN 16245-4:2013 - Fibre-reinforced plastic composites: Declaration of raw material characteristics - Part 4: Specific requirements for fabrics - defines the minimum information that fabric suppliers must declare for fabrics used to manufacture composite products (including impregnated products). It supplements the general rules in EN 16245-1 and focuses on uni‑axial and multi‑axial fabric materials. The standard also specifies requirements for the Certificate of Analysis (CoA) used to verify that delivered fabric properties conform to declared values.

Key topics

• Scope & applicability
  • Applies to fabrics (woven, knitted and other planar constructions) used as reinforcement in composite manufacturing, not to finished composite parts.
  • Covers uni‑axial and multi‑axial fabrics; some fabric types (woven roving, discontinuous fibre fabrics) are slated for later revision.
• Mandatory declaration items for fabrics
  • Identification (manufacturer product code/name), fabric type (UD, BIAX, TRIAX, QUADRIAX), fibre orientations, total nominal area weight, dimensions (length/width), defects, moisture content, loss of ignition, core tube inner diameter, expiry date, marking.
• Structural fibre declarations
  • Fibre identification, layer number (layer 1 facing roll centre), fibre manufacturer, fibre material type (glass, carbon, thermoplastic), linear density (tex), area weight per layer, size type/identification, size content (%), maximum gap between fibre bundles at stitch/knit points.
• Stabilising/support and assembly materials
  • Material identification, manufacturer, material/process type, orientation (if applicable), linear density, area weight, stitch/knit pattern, stitch length and gauge.
• Additional processes/materials
  • Declare processes that affect fabric (sizing, Z‑pinning, toughening), material identification, type and added area weight.
• Certificate of Analysis (CoA)
  • CoA must verify declared properties and follow referenced test methods and conditioning standards; manufacturer responsible for testing and declared tolerances.

Practical applications

• Useful for: fabric manufacturers, composite part producers, procurement teams, quality managers, test laboratories and certification bodies.
• Benefits:
  • Ensures material traceability and consistent product identification across supply chains.
  • Provides a standardized basis for quality control, incoming inspection and supplier audits.
  • Reduces production risk by verifying key parameters (area weight, fibre orientation, moisture, sizing).
  • Facilitates material selection for industries like aerospace, automotive, wind energy and marine composites.
