BS EN 15335discusses ceramic composites.. BS EN 15335 specifies the resonant beam method used for the determination of the dynamic elastic moduli of fibre reinforced ceramic matrix composites from 20 °C up to 2 000 °C in a vacuum or inert atmosphere.
BS EN 15335 applies to ceramic matrix composites with fibre reinforcement: short fibres, unidirectional (1D), bidirectional (2D), and tri-directional (xD, with 2 < x ≤ 3) which have at least orthotropic symmetry.
Note 1: Dynamic means that the elastic moduli are determined non-quasistatically
Note 2: The ceramic matrix composites with fibre reinforcement, listed above, are denoted as “composites” in the course of the document.
BS EN 15335 on resonant beam method for ceramic composite is useful for:
Ceramic composites are widely used in aerospace applications. They have the ability to withstand high temperatures and help in saving fuel at the same time. They also have a unique feature called elastic moduli. Elastic moduli determine the resistance to elastic. This is a powerful feature as it depicts the stiffness of the ceramics.
The resonant beam method is frequently applied for the determination of the dynamic elastic moduli.
BS EN 15335 provides a test method to determine the elastic properties. This shall ensure that ceramic composites perform as per the standard requirements. This makes BS EN 15335 important as it can help you improve the precision as well as the reliability of your ceramic composites. It can inform customers that ceramic composites follow the best industry practices.
