“…Flandin et al [18,19] first used nanoscopic conductive fillers with different aspect ratios in a thermoplastic matrix to monitor the applied macroscopic mechanical strain and the damage evolution during loading. Nanoscaled carbon black particles [8] as well as microscaled carbon black particles [20] have also been used to modify the matrix of glass-fibre reinforced thermosets. In these works, it was shown that external stress as well as apparent mechanical damage can be detected in these multiphase composites via electrical conductivity methods.…”

. Load and health monitoring in glass fibre reinforced composites with an electrically conductive nanocomposite epoxy matrix. Composites Science and Technology, Elsevier, 2009, 68 (7-8) In this work a new approach for condition monitoring was investigated, which, unlike other attempts, does not require additional sensors, but instead is performed directly by the measurement of a material property of the FRP. An epoxy resin was modified with two different types of carbon nanotubes and with carbon black, in order to achieve an electrical conductivity. Glass fibre reinforced composites (GFRP) were produced with these modified epoxies by resin transfer moulding (RTM). Specimens were cut from the produced materials and tested by incremental tensile tests and fatigue tests and the interlaminar shear strength (ILSS) was measured. During the mechanical tests the electrical conductivity of all specimens was monitored simultaneously, to assess the potential for stress/strain and damage monitoring. ACCEPTED MANUSCRIPT 2The results presented in this work, show a high potential for both, damage and load detection of FRP structures via electrical conductivity methods, involving a nanocomposite matrix.

“…To this aim 10x10x3mm 3 CnP-epoxy 8 samples [38] were cast in moulds, cured following the above reported procedure, and provided by electrical contacts made of silver paint on opposite sides. Different carbon loadings were chosen in the two types of samples due to the diverse CnP density and efficiency in reaching percolation.…”

“…In past years, self-monitoring polymer composite materials were proposed as innovative monitoring systems, that can provide contemporarily structural and sensing properties [1,2,3]. Such materials gained particular interest in the field of civil engineering applications, where the use of polymer composite reinforcing rods has become more and more attractive, in order to overcome corrosion problems, typical of steel reinforcements.…”

“…Therefore, CFGFRP is generally unsuitable for strain monitoring in the small or medium strain range. However, CPGFRP (carbon powder dispersed in glass-fibre-reinforced plastics) prepared by Muto et al [80], was superior to CFGFRP with respect to their capability of monitoring in the above-mentioned strain range. But CPFGRP suffered from difficulties of mass production and high cost.…”

Structural Health Monitoring (SHM) aims to develop automated systems for the continuous monitoring, inspection, and damage detection of structures with minimum labour involvement. The first step to set up a SHM system is to incorporate a level of structural sensing capability that is reliable and possesses long term stability. Smart sensing technologies including the applications of fibre optic sensors, piezoelectric sensors, magnetostrictive sensors and self-diagnosing fibre reinforced composites, possess very important capabilities of monitoring various physical or chemical parameters related to the health and therefore, durable service life of structures. In particular, piezoelectric sensors and magnetorestrictive sensors can serve as both sensors and actuators, which make SHM to be an active monitoring system. Thus, smart sensing technologies are now currently available, and can be utilized to the SHM of civil engineering structures. In this paper, the application of smart materials/sensors for the SHM of civil engineering structures is critically reviewed. The major focus is on the evaluations of laboratory and field studies of smart materials/sensors in civil engineering structures.
