Assessment of the Mechanical Behaviour of SiC Fibre Reinforced Magnesium Lithium Aluminosilicate Glass-Ceramic Matrix Composite Tested Under Uniaxial Tensile Loading

摘要

The mechanical behaviour under quasi-static uniax- ial tensile loading of SiC-MAS.L glass-ceramic composite material is investigated. The accumula- tion of damage in unidirectional specimens is char- acterized by the total number of transverse matrix cracks, N, and the reduction in the longitudinal Young's modulus, E. the micromechanical parame- Ters governing the matrix microcracking mechanism Are calculated.
