MECHANICAL TEST METHODS FOR CERAMIC-MATRIX COMPOSITES

The current state of mechanical test methodology for continuous fibre reinforced ceramic matrix composites (CMCs) is described and analysed based on comments made in the literature and on recent testing experie nce accumulated by the author. Practical problems of testing that have been encountered are discussed in relation to the development of ASTM and CEN standardised rest methods, Topics covered include flexural, t ensile, compressive, and shear testing, determination of elastic modul i and fracture toughness, extensometry, and high temperature testing.
