Material Bond of Fiber-reinforced Thermoset-thermoplastic Hybrids
- 50 Downloads
Using a new joining technology, KTM Technologies manufactures structurally highly stressed components from fiber-reinforced thermosets and thermoplastic functional elements. The material bond is based on a chemical coupling layer that is applied during the forming of the thermoset component. The process chain can be integrated into an existing production process with little effort.
Drawbacks of Common Techniques
A direct material bond of thermoset and thermoplastic structures is complex with the current, state-of-the-art techniques. Most of the time, the connection is generated by form fit, force closure, or by an indirect substance-to-substance bond, with the aid of an adhesive, to ensure the desired load transfer. These techniques require additional material, joining elements, or adhesives which have a negative impact on product weight. The current joining processes usually involve drilling, where the fibers are cut; as a result, the fiber structures are damaged and the components...
