Fine ceramics (advanced ceramics, advanced technical ceramics) - Mechanical properties of ceramic composites at ambient temperature in air atmospheric pressure - Determination of tensile properties of tubes
ISO 20323:2018 specifies the conditions for the determination of tensile properties of ceramic matrix composite tubes with continuous fibre-reinforcement at ambient temperature in air atmospheric pressure. This document is specific to the tubular geometries since fibre architecture and specimen geometry factors are distinctly different in composite tubes than in flat specimens.
ISO 20323:2018 provides information on the uniaxial tensile properties and tensile stress-strain response such as:
ISO 20323:2018 addresses, but is not restricted to, various suggested test piece fabrication methods. It applies primarily to ceramic and/or glass matrix composite tubes with a continuous fibrous-reinforcement:
Values expressed in this document are in accordance with the International System of Units (SI).
NOTE In most cases, ceramic matrix composites to be used at high temperature in air are coated with an antioxidation coating.
