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.
Claims20
A method for forming a composite comprising:
- grafting a binding polymer to a first surface of a thermoplastic component, the thermoplastic component comprising a thermoplastic composition at the first surface, the binding polymer including a plurality of epoxy groups, the grafting including reaction of a first portion of the plurality of epoxy groups with a reactive functionality at the first surface of the thermoplastic component;
- crosslinking the binding polymer via reaction of a second portion of the plurality of epoxy groups to form a crosslinked binding layer;
- and
- directly or indirectly binding a second surface of a thermoset component to the crosslinked binding layer, the thermoset component comprising a thermoset composition at the second surface, the second surface being directly or indirectly bonded to the crosslinked binding layer via reaction of a third portion of the plurality of epoxy groups.
