The effect of martensitic transformation in single Ni-Ti shape memory wire epoxy matrix composite was investigated. The Ni-Ti wire was received in as drawn condition and was subjected to three different heat treatments in order to obtain wires with different transformation characteristics. The in-situ observations of the interfacial debonding and sliding behaviour during the pull-out test were carried out. It is observed that when there is no phase transformation the debonding propagates rapidly whilst it is slow when there is wire phase transformation or matensitic reorientation. It is found that the debonding rate depends on the applied crosshead speed as well as the length change during phase transformation.
