THERMOPLASTIC/THERMOSET GRAFTED COMPOSITES

摘要

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.

主权项

1. A method for forming a composite comprising:
grafting a binding polymer to a surface of a thermoplastic component, 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 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 thermoset component to the crosslinked binding layer via reaction of a third portion of the plurality of epoxy groups.
