Thermoplastic/thermoset grafted composites

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.

Connector for non-cylindrical composite tubing and methods for making the same

A connector for non-cylindrical composite tubing and methods for making the same. The method may involve assembling a connector for a non-cylindrical composite tubing by loosely fastening a pair of bonding plates to an end plate; arranging the bonding plates in an inward configuration; applying an epoxy adhesive onto the outer faces of the bonding plates, inserting the bonding plates into the open end of the composite tubing, inserting the bonding plate fasteners through the through-holes of the composite tubing and tightly fastening the bonding plate fasteners into the bonding plates until the bonding plates engage against the inner surface of the composite tubing until the epoxy adhesive is uniformly distributed. The method may also include steps of removing the bonding plate screw fasteners and adding shims between each bonding plate and the inner surface of the composite tubing in order to maintain a predetermined thickness of the epoxy adhesive.

An amalgamation plate for joining a first component to a second component has a planar body configured to be placed between the first component and the second component, and a plurality of first protrusions extending from a first side of the planar body. The first protrusions are radially dispersed from an axis of the planar body, and are configured to be embedded within either the first component and the second component. The amalgamation plate may also have a plurality of second protrusions extending from a second side, opposite the first side, of the planar body. The second protrusions are radially dispersed from the axis, and are configured to be embedded within the other of the first component and the second component via application of force substantially along the axis. The first protrusions and the second protrusions may be radially symmetric about the axis of the planar body.
