“…The authors demonstrated also that fusion joining can replace adhesives, ensuring an increase in both the static and fatigue strength as compared to bonded coupons [ 122 ]. Murray and colleagues [ 123 ] developed manufacturing processes of thick glass fiber-reinforced acrylic thermoplastic resin wind turbine blade spar cap. They concluded that the thermoplastic resin system can be used for the manufacturing of wind turbine blades using vacuum-assisted resin transfer molding.…”

Various scenarios of end-of-life management of wind turbine blades are reviewed. “Reactive” strategies, designed to deal with already available, ageing turbines, installed in the 2000s, are discussed, among them, maintenance and repair, reuse, refurbishment and recycling. The main results and challenges of “pro-active strategies”, designed to ensure recyclability of new generations of wind turbines, are discussed. Among the main directions, the wind turbine blades with thermoplastic and recyclable thermoset composite matrices, as well as wood, bamboo and natural fiber-based composites were reviewed. It is argued that repair and reuse of wind turbine blades, and extension of the blade life has currently a number of advantages over other approaches. While new recyclable materials have been tested in laboratories, or in some cases on small or medium blades, there are remaining technological challenges for their utilization in large wind turbine blades.

“…Fiber reinforced Elium ® composites (FRECs) have still been under development by using various manufacturing techniques such as vacuum assisted resin transfer molding (VARTM) [6,7] and pultrusion [8]. Therefore, material characterization and a better understanding of the processing conditions, as well as mechanical performance are required to utilized FRECs in industrial applications.…”

The aim of this study is to evaluate the effect of the processing temperature on the interfacial failure of glass/Elium ® 150 composites. The vacuum assisted resin transfer molding technique (VARTM) was used to manufacture glass/Elium ® 150 composites at three different process temperatures: room temperature (24℃), 50℃ and 80℃. The interlaminar shear strength, mode I and mode II interlaminar fracture toughness of the laminates were determined by performing the short beam shear (SBS), double cantilever beam (DCB) and end notched flexure (ENF) tests, respectively. It was found that the increase in processing temperature improved the interlaminar shear strength, mode I and mode II interlaminar fracture toughness by approximately 41%, 66% and 227%, respectively. A combined compressive and shear failure mode was found in SBS tests. Fiber bridging was present for all the composite specimens in DCB tests according to the travelling recording camera images. Fracture surface images obtained by scanning electron microscopy (SEM) after the ENF tests revealed that a better fiber-matrix bonding and a ductile matrix failure were obtained for higher processing temperatures.

“…Recent studies highlighted that the novel resin-infused thermoplastic-based 3D-FRC is a suitable material to manufacture composite structures for superior impact resistance [ 2 , 31 ], damage tolerance [ 32 ] and energy absorption [ 33 ] applications. Murray et al [ 34 ] studied the flexure properties of a novel acrylic thermoplastic-based 2D-FRC and reported that the flexure strength and flexure modulus were almost similar. To the best of the author’s knowledge, no study has been dedicated to evaluating the flexure performance of novel acrylic thermoplastic-based 3D-FRC and their comparison with thermoset-based 3D-FRC.…”

The flexure response of novel thermoplastic (Elium®) 3D fibre-reinforced composites (FRC) was evaluated and compared with a conventional thermoset (Epolam®)-based 3D-FRC. Ten different types of sample 3D-FRC were prepared by varying fibre orientations, i.e., 0°, 30°, 45°, 60° and 90°, and resin system, i.e., thermoplastic and thermoset. The bending characteristics and failure mechanisms were determined by conducting a three-point bend test. Results elucidate that the on-axis specimens show linear response and brittle failure; in contrast, the off-axis specimens depicted highly nonlinear response and ductile failure. The thermoplastic on-axis specimen exhibited almost similar flexure strength; in comparison, the off-axis specimens show ~17% lower flexure strength compared to thermoset 3D-FRC. Thermoplastic 3D-FRC shows ~40% higher energy absorption, ~23% lower flexure modulus and ~27% higher flexure strains as compared to its thermoset counterpart.
