Smarter Leichtbau 4.1
About the project
At the end of 2019, the European Commission presented the European Green Deal to take action to avert the threat of climate change and environmental degradation, while providing a growth strategy for the transition to a modern, resource-efficient economy.
The current crisis, according to COVID 19, is also leading to a rethinking of supply chains and supply far beyond food.
Both aspects speak for smart lightweight construction, especially with renewable raw materials. They increase efficiency and improve sustainability for a wide range of applications.
Lightweight construction in all applications is a necessary aspect to save resources. In addition to the primary resources in production, it enables savings in operation due to lower weight, especially in constructions that are moved in some way. The use of renewable raw materials, especially as reinforcing fibres, enables the use of regional raw materials and regional production. The use of sensor technology enables an interface to the digital world and also contributes to further resource savings, as materials can be optimally utilised.
The independent EFRE application Smarter Lightweight Construction 4.1 builds on these key points and the results already achieved, and represents a significant new step in the work and cooperation.



Lightweight materials in nature are cellular structures
Fiber composites are stiffer and stronger
Continous fibres have excellent mechanical properties
Aim and goals of the project

The project Smarter Leichtbau 4.1 is following the project EFRE Smarter Leichtbau 4.0. Three parnters are working together on this project. Each of them focuses on one core competence:
- FH Kärnten – CUAS (3D printing of lightweight constructions)
- Kompetenzzentrum Holz (renewable raw materials)
- SAL GmbH (development of sensors and sensor techniques)
Building on the respective core competences of the three research institutions, the project Smarter Lightweight Construction 4.0 has created a common focus that is now to be further expanded. On the one hand, the expertise of the individual partners will be deepened, and on the other hand, the common ground will be expanded in order to draw greater, more sustainable benefits from the sum of the individual projects.
GOALS
- Integration of sensor technology for smart functionality or for efficient process control
- Non-destructive material testing and process analysis technology
- Force dependent path design with individual fiber orientation
- Printing strategies for high performance composites
- Implementation of a fourth axis

How are we working?
Process Design Overview

In order to achieve the goals of ERDF Smarter Lightweight Construction 4.1, the project is divided into several work packages above the three partners.
At the CUAS we are working on the following working packages:
