Center for Textile Lightweight Engineering

Technical Equipment

On an area of over 1,500 m², the Center for Textile Lightweight Engineering combines classic textile technology and innovative systems for composite production. The technical equipment on a semi-industrial scale enables both small pre-trials and the production of small series. The installed equipment in the research and test field are linked with a process control system, so that comprehensive data acquisition and evaluation is possible. The combination with the recorded consumption data, such as electricity, gas and compressed air consumption, as well as the environmental conditions, enables ecological and economic assessments of the done developments.

MC4 Project

"Multi-level Circular Process Chain for Carbon and Glass Fibre Composites" (MC4) is a European partnership having started in April 2022. It is a project consortium of 15 partners, including STFI, investigating circular approaches for the reuse of carbon and glass fibre composites. It develops process technologies and quality assurance methods that enable the economic recycling of carbon and glass fibre components. MC4 focuses on various reuse and recycling processes along the life cycle of composite components.

"Daniel Hölzl creates in GROUNDED a special link between the two worlds of art and technology by consistently implementing the idea of sustainability. With great attention to detail, he takes visitors up into the air before grounding them again with the harsh reality of recycling."

Christopher Albe, Head of Group Textile Lightweight Engineering at STFI

Apart from wax, carbon nonwovens are the main components the exhibited works are made of. The recycled materials form the basis of the raw material being reused demonstrating how circular economy can function.
