Abstract
Disclosed are thermoset/thermoplastic composites that include a thermoset component directly or indirectly bonded to a thermoplastic component via a crosslinked binding layer between the two. The crosslinked binding layer is bonded to the thermoplastic component via epoxy linkages and is either directly or indirectly bonded to the thermoset component via epoxy linkages. The composite can be a laminate and can provide a route for addition of a thermoplastic implant to a thermoset structure.
Claims12
A composite comprising:
- a thermoset section including a first length of a first tow, the first tow comprising continuous fibers impregnated in a thermoset polymeric composition;
- a hybrid section including a second length of the first tow and a first length of a second tow, the second tow comprising continuous fibers impregnated in a thermoplastic polymeric composition, the first tow terminating in the hybrid section and the second tow initiating in the hybrid section, the hybrid section further including a binding layer between the second length of the first tow and the first length of the second tow, the binding layer comprising a crosslinked binding polymer, the binding layer being bonded to the thermoplastic polymeric composition of the second tow via a linkage that includes the reaction product of a first epoxy functionality of the binding layer with a functionality of the thermoplastic polymeric composition, the binding layer being directly or indirectly bonded to the thermoset polymeric composition of the first tow via a linkage that includes the reaction product of a second epoxy functionality of the binding layer with a functionality that is a constituent of or that is directly or indirectly bonded to the thermoset polymeric composition;
- and
- a thermoplastic section including a second length of the second tow.
