“…Some studies use a multivariable data analysis to characterise the development of damage by acoustic emission [5,8,13]. Many of them have shown a clear correlation between acoustic emission amplitude and damage mechanisms in composite [6,14]. Thence, many authors have developed various AE experimental programs adapted to different materials.…”

Abstract. This paper proposes to develop an experimental program to characterize the type and the development of damage in composite with complex microstructure. A multi-scale analysis by acoustic emission has been developed and applied to hemp fibre woven fabrics/epoxy composite. The experimental program consists of tensile tests performed on single yarn, neat epoxy resin and composite materials to identify their AE amplitude signatures. A statistical analysis of AE amplitude signals has been realised and correlated with microscopic observations. Results have enabled to identify three types of damage in composites and their associated AE amplitudes: matrix cracking, interfacial debonding and reinforcement damage and fracture. Tracking of these damage mechanisms in hemp/epoxy composites has been performed to show the process of damage development in natural fibre reinforced composites.

In the second stage E/E 0 reduction in a manner almost linear with the number of cycles, and results from damage propagation and the break of the first fibers [17][18][19].…”

Aluminized glass fiber composite with epoxy and polyester matrix were used in this work in order to study fatigue properties and its comparison to conventional glass fiber composites. Until now aluminized glass fiber materials have been only used as decoy flares in military applications. The innovative advantages of these composites, using modified fibers, are potentially the improvement of thermal and electrical conduction. The main objective of this work was to study the fatigue damage of coated fiber materials using stiffness loss and potential drop techniques. The failure mechanisms were analyzed using microscopy. Fiber contents and the resin effects in the fatigue strength were also tested and discussed.

It is a big challenge to relate acoustic emission (AE) signal events to specific damage modes developed in composites under hygro-thermo-mechanical loading. This study provides further insight into the AE monitoring of a 3D angle interlock (AI) glass fibre composite and has revealed the complex nature of the relationship between the principal characteristics of recorded AE events on the one hand and the mechanical behaviour of the material on the other. Because the tested material here is transparent, the development of cracks can be observed in-situ during the test using optical images on the specimen. This paper presents experimental results on the use of AE on 3D AI glass fibre composites for structural health monitoring (SHM) of matrix cracks, during quasi-static tension of flat plates.
