Strong CO2 -reduced components made from fiber-reinforced biopolymers

Development of sustainable, durable components for demanding operating conditions

Bauteile aus faserverstärkten Biopolymeren

Plastic components offer great potential for reducing emissions. In the "COOPERATE" project, Fraunhofer LBF and partners are developing methods to fundamentally improve product design and layout in terms of life cycle assessment and sustainability . The combination of substituting petroleum-based plastics with bio-based alternatives and developing improved methods for the material-saving design of components, will reduce the CO2 demand of plastic components in sophisticated, industrial applications and consumer goods by up to 75 percent.

By reducing the amount of material used and using biobased composites, the CO2 requirement in the production of plastic components in consumer goods is to be cut by up to 75 percent. The project partners are working together to develop material-saving design methods and bio-based composites for durable and highly stressable components - with specific application examples from the field of automotive engineering serving as a benchmark.

Significant savings in material-related greenhouse gas emissions

In order to reduce the amount of material used, the design processes are to be improved for use in consumer goods subject to vibration. This will increase the lightweight construction potential and the associated resource efficiency in the downstream as well. Among other things, the project is developing new calculation methods that take into account the influences of manufacturing on the quasi-static and dynamic behavior of the materials. A prerequisite for exploiting the lightweight potential is the precise characterization of the materials used and the validation of the simulation methods.

The use of bio-based materials achieves significant savings in material-related greenhouse gas emissions. In the "COOPERATE" project, the partners are jointly researching substitutes with significantly lower proportions of petrochemically produced components and optimizing them for use in consumer goods subject to vibration. Since bio-based materials achieve a different performance than conventional materials, the climate-neutral substitutes are being further developed in this project and practice-relevant investigations of the material properties are being carried out with regard to structurally important characteristic values.

Methodological competence at the Fraunhofer LBF

The new methods and the improved material properties pave the way for the use of new plastics in other fields of technology. Overall, the "COOPERATE" project is pursuing the goals of lightweight construction-related development of resource-efficient processes and the substitution of greenhouse gas-intensive materials.
