“…Raman spectroscopy is one of the promising tool for the study of composite micromechanics, since it enables the point-to-point determination of stress and strain along the fibre/matrix interface in a variety of systems [157][158][159][160]. Raman spectroscopy has been extensively used for micromechanical studies of composite interfaces by many researchers [161][162][163].Moreover, the stresses and strains in the fibres and interface can be mapped at all levels of strain prior to overall catastrophic failure [164]. The micromechanical test methods give single-point values of interfacial stress obtained only through failure of the fibre/matrix interface, whereas the Raman technique can evaluate the variation of the interfacial shear stress along the fibre/matrix interface.…”

“…The extent of this damage of a GFRP submerged at either ambient or elevated temperature, is also a function of the specific liquid in which the composite is immersed. Interface damage has been reported by Cervenka et al (2004) in composites immersed in water vapour. Damage mechanisms have also been considered by Foulc et al (2005), who identified the occurrence of plasticity, chemical degradation, morphological evolution and interface damage with debonding.…”

Experimental evidence indicates that the main damage mechanisms found in fibre-reinforced composites under static loading or environmental action are matrix damage, fibre damage and interface damage, leading to various forms of strong inhomogeneities at the micromechanical level. The main objective of this paper is to identify the stress redistributions that take place at the unit cell level, in which damage has already occurred due to an independent process. A deterministic approach is carried out to illustrate the main features of the transverse behaviour of a unidirectional fibre-reinforced composite under static loading. Damage is modelled by means of interface defects, in which the number and size of defects are considered as parameters of the damaged configuration and also by changes in material properties. The two-dimensional problem is solved using a general purpose finite-element code. The results show the extent of damage propagation to be expected in several configurations with inhomogeneities.

The chapter reviews and illustrates with examples the many diverse applications of vibrational spectroscopy to the study of polymer composites, which are broadly defined as materials consisting of a polymeric (thermoplastic or thermoset) matrix reinforced with fibers (carbon, glass, polymer) or inorganic particles. After some discussion of the experimental difficulties that must be dealt with in obtaining spectra of these heterogeneous materials, the literature is reviewed under the following subject categories: quality control of polymer composites; studies of various reinforcement materials, their surface treatments, and their interaction with matrices (carbon fibers and particles, carbon nanotubes, glass, silica, silicates and nanosilicates, polymeric fibers, inorganic particulate fillers, fillers derived from plant sources); thermoplastic matrices (crystallinity, orientation); thermoset matrices (the study and monitoring of curing by mid‐infrared, near‐infrared, and Raman spectroscopies); environmental degradation. The chapter also covers the use of Raman spectroscopy to monitor strain in composite materials.
