Non-destructive evaluation of erosion damage on E-glass/epoxy composites

A Taguchi approach for investigation of solid particle erosion response of needle-punched nonwoven reinforced polymer composites: Part II

“…The erosion rate is lower for composites with short fibers compared to composites with long, unidirectional reinforcement fibers [3]. The sequence of damage from erosion in fiber reinforced composites is as follows: first local removal of material in the resin-rich zones, after that erosion in the fiber zones associated with breakage of fibers and finally erosion of the interface zones between the fibers and the adjacent matrix [4]. To examine the importance of polymer composites and to study the effect of fiber content in composites, considerable study has been done on solid particle erosion of polymer composites by the many researchers such as Tamer Sınmazcelik [5], Tilly and Sage [6], Tewari et al [7][8][9][10], using different types of fibers like short, long and multidirectional carbon and glass fibers with various types of resins.…”

High-temperature slurry erosion of vinylester matrix composites – The effect of test parameters

“…Thus, the erosion behaviour of a wide range of fibre-reinforced polymer composites with different matrix materials has recently been evaluated. These include glass and carbon fibre reinforced epoxy [3][4][5], polyester [6][7][8][9], polyetheretherketone (PEEK) [10], polyetherimine (PEI) [11,12] and polyphenylenesulphide (PPS) [13], to name a few. Typically, the effect of the reinforcement material, concentration, type and orientation as well as its adhesion to the matrix has been studied in these investigations.…”

An information processing method for acoustic emission signal inspired from musical staff

“…In the aforementioned fields, parameter analysis methods are often adopted to cope with the diversity and uncertainty of the generated signals [9]. The characteristic parameters describing AE signals include peak amplitude, event duration, rising time, event count, ring-down counts, and energy consumption [10][11][12][13][14][15]. The definitions of these parameters are shown in Fig.…”
