适用范围：This European Standard specifies the resonant beam method for the determination of the dynamic elastic moduliof fibre reinforced ceramic matrix composites from 20 °C up to 2 000 °C in vacuum or inert atmosphere. TheYoung´s moduli and the shear moduli for different orientations with respect to the main axes of symmetry of thecomposite can be obtained.This document applies to ceramic matrix composites with fibre reinforcement: short fibres, unidirectional (1D),bidirectional (2D), and tridirectional (xD, with 2 < x ≤ 3) which have at least orthothropic symmetry.NOTE 1 Dynamic means that the elastic moduli are determined non-quasistatically, i.e. under adiabatic conditions, aswith the ultrasonic method set out in ENV 14186. The elastic moduli determined by this method may not be compared withmoduli obtained in an isothermal condition by stressing statically or quasistatically as with EN 658-1, EN 658-2, EN 1892,EN 1893, EN 12290 and EN 12291.NOTE 2 The ceramic matrix composites with fibre reinforcement, listed above, are denoted as “composites” in thecourse of the document.
