This paper examines the damage process of fiber reinforced glassmatrix composites under tensile loading. The tensile damageinitiation and growth in BN-coated HI-NICALON SiC fiber reinforcedglass matrix cross-ply composites were experimentally clarified byreplica observalions. An improved shear-lag model with two majorcracks, which penetrate both 0 and 90 degree plies, were used topredict the stress-strain behavior. This model reasonably wellpredicted the stress-strain curve until matrix cracks in 0 degree plysaturated.
