Room temperature tensile tests at variable strain-rates in a Nicalon{reg_sign}/CAS continuous fibre reinforced glass ceramic matrix composite, with cross-ply architecture [(0/90){sub 3}]{sub s}, are presented and analysed with reference to deformation and failure mechanisms (matrix cracking, fibre debonding, pullout, etc.). The experimental strain rates used range from 10{sup -4} to 10{sup +1} s{sup -1}. It is observed that, within the examined experimental range, the strain energy density increases as the strain rate increases, even when fibre pullout extent decreases. This is explained by a larger matrix degradation.
