BS ISO 18610:2016规定了一种超声波方法，用于测定材料的弹性张量分量 室温下的陶瓷基复合材料。杨氏模量剪切模量与泊松 系数，可以通过弹性张量的分量来确定。本文件适用于具有连续纤维增强的陶瓷基复合材料: 单向（1D）、双向（2D）和三向（×D，2<×D）≤ 3） 至少有 正交各向异性对称，其材料对称轴已知。该方法仅在使用的超声波波长大于材料厚度时适用 具有代表性的基本音量，因此对音量的频率范围施加了上限 使用传感器。注:通过该方法获得的特性可能无法与ISO 15733获得的模量进行比较， ISO 20504和EN 12289。交叉引用:ISO 3611ISO/IEC 17025EN 1389ISO 653ISO 19634ISO 15733ISO 20504EN 12289EN 12668-1EN 12668-2EN 12668-3CEN/TR 13233购买本文件时提供的所有当前修订版均包含在购买本文件中。

BS ISO 18610:2016 specifies an ultrasonic method to determine the components of the elasticity tensor of ceramic matrix composite materials at room temperature. Young's moduli shear moduli and Poisson coefficients, can be determined from the components of the elasticity tensor.This document applies to ceramic matrix composites with a continuous fibre reinforcement: unidirectional (1D), bidirectional (2D), and tridirectional (×D, with 2 < × ≤ 3) which have at least orthotropic symmetry, and whose material symmetry axes are known.This method is applicable only when the ultrasonic wavelength used is larger than the thickness of the representative elementary volume, thus imposing an upper limit to the frequency range of the transducers used.NOTE Properties obtained by this method might not be comparable with moduli obtained by ISO 15733, ISO 20504 and EN 12289.Cross References:ISO 3611ISO/IEC 17025EN 1389ISO 653ISO 19634ISO 15733ISO 20504EN 12289EN 12668-1EN 12668-2EN 12668-3CEN/TR 13233All current amendments available at time of purchase are included with the purchase of this document.
