Integrated manufacturing of REciclable multi-material COmposites for the TRANSport sector
THERMOSET RESIN CONTAINING ION CLEAVABLE DISILOXANE
A thermoset resin including a plurality of crosslinked ion cleavable disiloxane units incorporated therein from a disiloxane monomer. The thermoset resin is polyester, vinyl ester, polyurethane epoxy, polyurea, rubber, a crosslinked thermoplastic, or a combination thereof. The plurality of crosslinked ion cleavable disiloxane units arc cleavable by a fluoride ion. A composite material including a cured matrix formed of the thermoset resin and a plurality of reinforcing fiber embedded therein. The reinforcing fibers being glass, carbon, aramid, natural, basalt, boron, silicon carbide, polymer, or a combination thereof. The composite material being entirely recyclable. A process for recycling the composite material includes adding the composite material to solvent in a container; introducing fluoride ions to solvent in the container; and maintaining under conditions to dissolve the matrix material and to free more than 95% by weight of the reinforcing fibers from the matrix material.
