Valorization of basalt and glass fibres from vacuum infused acrylate-based composites by coupling mechanical and dissolution recycling pathways

Year: 2024

Type: article

Abstract: This work aims to couple two recycling pathways, i.e., a conventional mechanical recycling by grinding/sieving and resin dissolution in the case of vacuum infused Elium©/glass fabrics or Elium©/basalt fabrics composites . Quasi-static (tensile and bending) and dynamic (DMA) properties are evaluated on polyamide-6 (PA6) extruded specimens containing these recyclates , that underwent or not a dissolution in acetone. Commercial short glass and basalt fibres were used as a reference compared to waste products. Results show that the coupling allows to increase the fibre content in PA6 composites preserving a good interfacial adhesion , compared to a simple grinding process without dissolution. Tensile and flexural mechanical properties of the second-generation composites are increased. There is almost no variation in fibre length when comparing the reference, grinding alone and grinding/dissolved fibres. DMA allows to observe that in the case of short fibres within PA6, there is an increase of loss modulus especially.
