Advanced technical ceramics - Ceramic composites - Methods of test for reinforcement - Part 3: Determination of filament diameter and cross-section area

This part of EN 1007 specifies three methods for the determination of the diameter and cross-section area of ceramic single filament, as used in fibre reinforcement of ceramic composites. Note: The cross-sectional area of filaments from different suppliers will vary significantly. The term "diameter" applies both to circular cross-section ("true diameter") and non-circular cross-sections ("apparent diameter").

Hochleistungskeramik - Keramische Verbundwerkstoffe - Verfahren zur Prüfung der Faserverstärkungen - Teil 3: Bestimmung des Faserdurchmessers und -querschnitts

Dieser Teil von EN 1007 legt die Bedingungen für drei Verfahren zur Bestimmung des Durchmessers und der Querschnittsfläche einer keramischen Einzelfaser, wie sie zur Faserverstärkung keramischer Verbundwerkstoffe genutzt wird, fest.
ANMERKUNG   Die Querschnittsfläche der Fasern von verschiedenen Herstellern schwankt beträchtlich. Der Begriff "Durchmesser" wird sowohl auf kreisförmige Querschnitte ("wahrer Durchmesser") als auch für nicht-kreisförmige Querschnitte ("scheinbarer Durchmesser") angewendet.

Céramiques techniques avancées - Céramiques composites - Méthodes d'essai pour renforts - Partie 3: Détermination du diametre et de la surface de la section transversale des filaments

La présente partie de l'EN 1007 spécifie trois méthodes d'essai pour la détermination du diametre et de la surface de la section transversale des filaments de céramique utilisés comme renforts des composites céramiques.
NOTE   La forme de la section transversale des filaments peut varier de façon significative d'un fabricant a l'autre. Le terme " diametre " s'applique a la fois aux filaments dont la section est circulaire (" diametre vrai ") et aux filaments dont la section n'est pas circulaire (" diametre apparent ").

Standard the status of a national standard without any alteration. Up-to-date lists and bibliographical references concerning such national

standards may be obtained on application to the Management Centre or to any CEN member.

This European Standard exists in three official versions (English, French, German). A version in any other language made by translation

under the responsibility of a CEN member into its own language and notified to the Management Centre has the same status as the official

versions.

1 Scope

This part of the European Standard specifies the conditions for the determination of the diameter and cross-section

area of ceramic single filament, as used in fibre reinforcement of ceramic composites for three methods.

NOTE The cross-sectional area of filaments from different suppliers will vary significantly. The term “diameter” applies both

to circular cross-section (“true diameter”) and non-circular cross-sections (“apparent diameter”).

2 Principle

The diameter and cross-section area of the ceramic filament may be measured by three methods, as follows:

a) the longitudinal profile method (Method A), whic
