The interface between constitutive elements always plays a crucial role on the global performances of composites. Among smart materials, FO and NiTiNOL are the most popular to be used as embedded sensors and actuators in structures. Nevertheless, their adhesion properties with the host materials are not still well known and few experimental data can be found in the literature also due to the lack of the specific testing methods. The aim of this work is to give a contribute to the study of the behavior of such interfaces. Two different FO having poly-acrylate and poly-imide coating were embedded in epoxy resin blocks and their interface was characterized adopting a Pull-Out tests. In the same way the adhesion between resin and NiTiNOL wires was evaluated both in austenite and in martensite phase.

Abstract
The interface between constitutive elements always plays a crucial role on the global performances of composites. Among smart materials, FO and NiTiNOL are the most popular to be used as embedded sensors and actuators in structures. Nevertheless, their adhesion properties with the host materials are not still well known and few experimental data can be found in the literature also due to the lack of the specific testing methods. The aim of this work is to give a contribute to the study of the behavior of such interfaces. Two different FO having poly-acrylate and poly-imide coating were embedded in epoxy resin blocks and their interface was characterized adopting a Pull-Out tests. In the same way the adhesion between resin and NiTiNOL wires was evaluated both in austenite and in martensite phase.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
