[3] Schematic illustration of the recycling process for waste SRCs.

Caption

▲ The flame-retardant composite is fabricated by alternately stacking 1) flame-retardant-containing films and 2) reinforcing fiber sheets to form a structure of five or more layers, followed by hot pressing at 130 °C under 10 bar. The films are prepared by mixing an eco-friendly polymer with an eco-friendly flame retardant, along with a small amount of an additive (compatibilizer) to facilitate uniform mixing of the polymer and flame retardant. The polymer–flame retardant–additive mixture is then hot-pressed at 130 °C under 10 bar to form a film.

▲ In this study, the film, reinforcing fibers, and additive used to improve compatibility are all based on materials with the same chemical structure, making the composite easier to recycle than conventional fiber-reinforced composites composed of dissimilar materials.
