Fine ceramics (advanced ceramics, advanced technical ceramics) — Mechanical properties of ceramic composites at ambient temperature in air atmospheric pressure — Determination of tensile properties ISO 15733:2026

Publication date:   Jun 12, 2026

Scope

This document specifies the conditions for determining the tensile properties (including tensile modulus, Poisson’s ratio, strength, strain at maximum force and fracture strain) of ceramic matrix composite materials with continuous fibre reinforcement at room temperature. This document applies to all ceramic matrix composites with a continuous fibre reinforcement, including unidirectional (1D), bi-directional (2D), and multi-directional (xD, with x > 2), reinforcement, loaded along a principal axis of reinforcement.
NOTE            In most cases, ceramic matrix composites to be used at high temperature in air are coated with an antioxidation coating.
