WEB Experimental Investigation of Thermoset/Thermoplastic Hybrid Structures

Room 1

The combination of thermoset and thermoplastic fibre-reinforced plastic composites allows the production of highly resilient, cost-effective and fully automated structural components. The goal is to combine automatically produced filament winding structures made of endless unidirectional carbon fibre reinforced epoxy matrix (CFRP) with short glass fibre reinforced polyamide (PA6GF30) injection moulding material. The CFRP components are used to transfer the main loads, such as applied forces. The injection moulding structures take on additional functions, such as supporting functions or the creation of plane areas that are not highly loadable. In this way, components with Class-A surfaces and highly efficient load-transmitting truss structures can be produced.

To avoid subsequent joining, the cured endless CFRP structures are over moulded with PA6GF30 in the injection moulding process. To ensure that the injection moulding structures are also used as load transfer or support, there must be a significant joint strength between the two materials. On the one hand, this allows shear forces from one CFRP strand to be transferred to the next strand via the PA6GF30 support material. On the other hand, forces can also be introduced via the thermoplastic structure and transferred into the CFRP structure.
