Fine ceramics (advanced ceramics, advanced technical ceramics) - Reinforcement of ceramic composites - Determination of distribution of tensile strength and tensile strain to failure of filaments within a multifilament tow at ambient temperature (ISO 22459:2020)

This document specifies the conditions for the determination of the distribution of strength and rupture strain of ceramic filaments within a multifilament tow at room temperature by performing a tensile test on a multifilament tow.
This document applies to dry tows of continuous ceramic filaments that are assumed to act freely and independently under loading and exhibit linear elastic behaviour up to failure. The outputs of this method are not to be mixed up with the strengths of embedded tows determined by using ISO 24046 [1].

Hochleistungskeramik - Faserverstärkungen von keramischen Verbundwerkstoffen - Bestimmung der Verteilung von Zugfestigkeit und Zugdehnung bis zum Versagen von Filamenten innerhalb eines Multifilamentkabels bei Raumtemperatur (ISO 22459:2020)

Dieses Dokument legt die Bedingungen für die Bestimmung der Verteilung von Festigkeit und Bruchdehnung von Fasern innerhalb eines Faserbündels bei Raumtemperatur fest, indem ein Zugversuch an einem Faser¬bündel durchgeführt wird.
Dieses Dokument gilt für unbeschichtete Faserbündel aus keramischen Endlosfasern, von denen angeno-mmen wird, dass sie sich unter Beanspruchung frei und unabhängig verhalten und bis zum Bruch ein linear-elastisches Verhalten zeigen. Die Ergebnisse dieses Verfahrens sind nicht mit den Festigkeitswerten von eingebetteten Faserbündeln zu verwechseln, die mithilfe von ISO 24046  bestimmt wurden.

Céramiques techniques - Renfort de céramiques composites - Détermination de la distribution de la résistance en traction et de la déformation à la rupture en traction de filaments dans un fil multifilamentaire à température ambiante (ISO 22459:2020)

Le présent document spécifie les conditions de détermination de la distribution de la résistance et de la déformation à la rupture de filaments céramiques dans un fil multifilamentaire à température ambiante, en réalisant un essai de traction sur un fil multifilamentaire.
Ce document s'applique aux fils secs de filaments céramiques continus qui sont supposés se comporter librement et indépendamment sous charge et avoir un comportement linéaire élastique jusqu'à la rupture. Il ne faut pas confondre les résultats de cette méthode avec les résistances de fils imprégnés déterminées à l'aide de l'ISO 24046[1].

Fina keramika (sodobna keramika, sodobna tehnična keramika) - Ojačitev keramičnih kompozitov - Ugotavljanje porazdelitve natezne trdnosti in deformacij/obremenitev vlaken v svežnjih pri temperaturi okolice (ISO 22459:2020)

Ta dokument določa pogoje za ugotavljanje porazdelitve trdnosti in deformacij/obremenitev keramičnih vlaken v svežnjih pri temperaturi okolice z izvedbo nateznega preskusa na svežnju.
Ta dokument se uporablja za suhe svežnje neprekinjenih keramičnih vlaken, za katere se domneva, da delujejo prosto in neodvisno pod obremenitvijo ter izkazujejo linearno elastično obnašanje do pretrganja. Rezultati te metode se ne smejo zamešati s trdnostmi vdelanih svežnjev, določenih v standardu ISO 24046 [1].
