“…The importance of moulding methods for in-situ polymerization of Elium ® based composites has recently been dealt with only in fewer than five papers per year. The same trend is observed with respect to the polymerization (Han et al, 2020), weldability (Bhudolia et al, 2020b), and recycling of Elium ® based FRP composites (Bel Haj Frej et al, 2021;Khalili et al, 2021).…”

Reactive Processing of Acrylic-Based Thermoplastic Composites: A Mini-Review

2022

The demand for thermoplastic composites is continuously increasing because these materials offer many advantages over their thermoset counterparts, such as high toughness, long storage time, easy repairing and recycling, and ability to be thermoformed and heat-welded. However, the manufacturing of thermoplastic composite parts using liquid composite moulding techniques (e.g. resin transfer moulding, vacuum assisted resin transfer moulding … ) is often tricky in the case of melt processing where high temperature and pressure should be chosen to impregnate the fibre reinforcement because of the high melt viscosity of thermoplastics. These issues may be overcome by means of reactive processing where a fibrous preform is first impregnated by a low viscosity mono- or oligomeric precursor and the polymerization of the thermoplastic matrix then occurs in-situ. This article draws a state of the art on the manufacturing characteristics of continuous fibre reinforced acrylic-based reactive thermoplastics (e.g. polymethymethacrylate (PMMA) such as Elium®), which are becoming more and more popular compared to other fast curing thermosets and thermoplastics for in-situ polymerization. Techniques for the in-situ polymerization of methymethacrylate monomers, characterization and modelling of the rheological properties and polymerization kinetics, and some manufacturing related issues such as polymerization shrinkage are reviewed. Particular features of the use of reactive PMMA in different manufacturing techniques of continuous fibre reinforced composites and potential industrial applications are also introduced. Finally, some perspectives for the academic research and industrial development are proposed.

“…Sustainability of composites in general in the marine industry was often emphasized in terms suggesting that composite materials offer the possibility of building lighter vessels that can carry more cargo and/or produce lower emissions, with the expansion of the maintenance intervals [41]. However, potential sustainability needs to be validated, since different types of composites react differently when exposed to harsh marine environment.…”

Fiber reinforced polymer (FRP) composites coupons were exposed to real sea environment to assess the influence on the mechanical behavior of composite materials used in the construction of marine structures. Real-life sea environment conditions were opted for instead of the more common simulated and laboratory versions of seawater in the attempt to obtain more realistic structural modeling environmental input design parameters for marine structures. Exposure was performed over prolonged time span instead of the usual accelerated tests. Epoxy and polyester resins, reinforced with glass fibers in three fiber layout configurations, were used to manufacture standardized tensile testing coupons. Mass changes due to seawater absorption, microorganism growth, changes in tensile strength (standard tensile tests), and surface morphology of the coupons were evaluated after 6- and 12-month long periods of submersion in the sea in the Rijeka bay, Croatia. All specimens showed mass increase due to water absorption and growth of attached algae and sea microorganisms. Various levels of reduction in tensile strength, depending on the fiber layout configurations, were observed. Significant changes in the matrix material structure were noticed, effectively producing “voids”. Based on these results, sustainability of FRP composites in marine environment is addressed and discussed.

“…Also, when the nature of the fibers is different from that of the matrix, recycling may involve the use of complex chemistry or energy-intensive processes. For example, for a carbon-reinforced composite, pyrolysis in an inert atmosphere reactor and depolymerization have been proposed to reuse the materials [2]. To overcome this problem, a concept of composites has been proposed by Capiati and Porter [3].…”

Self-reinforced composites combine lightness and increased recyclability than conventional composites. To position them within the industrial composites market (conventional composites) and simultaneously highlight their potential in a given application context, it is necessary to analyze their mechanical properties for possible exploitation. For this purpose, compression molding has been used to manufacture different composites. In this short paper, the specific tensile properties of polyethylene matrix composites reinforced with glass, carbon, flax, and polyethylene fabrics, respectively, are compared at room temperature. The results give an excellent perspective to self-reinforced polyethylene.
