Project Details
Description
Forms of mobility are experiencing a paradigm shift, led by e-mobility and Urban Air Mobility, with lightweight construction emerging as a keytechnology. Lightweight materials are crucial for fuel-efficient vehicles in the automotive and aviation industries. In particular, compositematerials enable significant weight reductions and make a significant contribution to achieving the sustainability goals of the EU and UN.
The production of composite components has increased significantly in Austria, highlighting the enormous demand for composite materials.The recycling of composite materials with thermosetting matrix poses a challenge, but thermoplastics offer an alternative matrix solution thatallows simpler recycling and generates the foundation for circular economy.
In a previous project design guidelines for welded carbon fiber reinforced thermoplastics (CFRTP) joints are studied based on mechanicaltesting, processing technology, as well as structural simulation at coupon- and component-level.
"MicroWeld" analyses the micromechanical behavior of CFRTP and welded CFRTP joints. Also, an existing continuum damage model is to beexamined for its suitability for carbon fiber-reinforced thermoplastics and CFRTP welds and when feasible further developed. The necessarymaterial data are to some extent available from the previous project and are further investigated by mechanical test methods accompanied byfor example acoustic emission.
The dissertation project aims to understand the mechanical behavior of CFRTP welded joints from the micro- to the macro- and up to thecomponent-level. Thus, "MicroWeld" makes an essential contribution to the broad application of thermoplastic composites and CFRTP weldsand offers solutions for future challenges in the dynamic areas of e-mobility and Urban Air Mobility by using these sustainable, high-ratematerials and joining techniques.
