(Main)Advanced technical ceramics - Mechanical properties of ceramic composites at high temperature under inert atmosphere - Determination of fatigue properties at constant amplitude
General Information
- Abstract
This European Standard specifies the conditions for the determination of constant-amplitude of load or strain in uniaxial tension/tension or in uniaxial tension/compression cyclic fatigue properties of ceramic matrix composite materials (CMCs) with fibre reinforcement for temperature up to 2 000 °C under vacuum or a gas atmosphere which is inert to the material under test.
NOTE Test environments are specified which are intended to prevent the material under test from chemically reacting with them.
This European Standard applies to all ceramic matrix composites with fibre reinforcement, unidirectional (1D), bi-directional (2D), and tri-directional (xD, where 2 < x 3).

Overview
EN 15158:2006 is a CEN European Standard that defines a test method for determining the constant‑amplitude cyclic fatigue properties of ceramic matrix composites (CMCs) with fibre reinforcement at high temperatures (up to 2 000 °C) under vacuum or inert gas atmospheres. It covers uniaxial tension/tension and tension/compression fatigue testing for unidirectional (1D), bi‑directional (2D) and multi‑directional (xD, 2 < x ≤ 3) CMCs and specifies environment controls intended to prevent chemical reaction between the test atmosphere and the material.
Key topics and technical requirements
- Test principle
- Two methods: Method A (load‑control) - cycling between constant stress levels; Method B (strain‑control) - cycling between constant strain levels.
- Record total number of cycles and time to failure (Nf, tf); optional periodic stress‑strain recording to extract damage parameters.
- Temperature & atmosphere
- Tests up to 2 000 °C in vacuum or a gas atmosphere inert to the material; controlled temperature zone must be within ±50 °C of the test temperature.
- Specimens
- Applies to fibre‑reinforced CMCs (1D, 2D, xD). Standards specify specimen preparation, gauge length definition, and number of specimens required.
- Apparatus & measurement
- Hydraulic fatigue test machine (load or strain control) with cycle counter; force measurement complying with EN ISO 7500‑1 (grade 1).
- Gas‑tight test chamber for atmosphere control; heating system that maintains temperature uniformity in the controlled zone.
- Extensometry compatible with test temperature and frequency; conforming to EN ISO 9513 (class 1 or better).
- Load train, grips and alignment must avoid changes due to heating; cooled‑grip techniques are described.
- Damage parameters
- Examples include residual strain at zero load, secant elastic modulus (relative damage), hysteresis loop area (internal friction), and evolution of maximum/minimum strains.
- Outputs
- Life‑time diagrams (stress/strain amplitude vs. Nf or tf), damage evolution plots, and residual property assessment for unfailed specimens.
Applications and users
- Who uses it
- Materials engineers, test laboratories, CMC manufacturers, aerospace and power‑generation component developers, research institutes, and quality/control departments.
- Practical uses
- Characterizing high‑temperature fatigue life of CMCs for turbine components, thermal protection systems, combustion liners, and other high‑temperature structural parts.
- Supporting design margins, material selection, durability assessment, and certification testing where inert atmospheres or vacuum are required to avoid oxidation.
