Composites United e. V. (CU), one of the world’s largest networks for fiber-based multi-material lightweight design, emerged by the two associations Carbon Composites e. V. and CFK Valley e. V. About 350 members have joined to form this high-performance industry and research association to jointly develop lightweight design solutions for the future.

Vision &

By 2025 we will develop into an internationally recognized association for the sustainable use of multi-material lightweight design and position the group of hybrid high-performance lightweight design composites in global competition as ecological and economic added value.

We promote the industrial use of hybrid high-performance lightweight design composites and support their sustainable use.
In order to achieve this goal, we support our members in the targeted acquisition of national and international projects, the presentation of their skills at national and international events/trade fairs and through specific educational offers.


Expansion of services for the members of the association


Implementation of regional and national conferences


Networking of the members connected by the clusters and networks


Advice to politicians on questions concerning fibre-reinforced high-performance materials


Support of members in R&D activities


Creating access to international markets and knowledge


Composites United is looking for partners around the world to drive the development of composite technology.


Composites United consists of approximately 350 members from various industries, regions and countries, companies and institutions.


Joint projects bring the members of the network together on important topics in the industry and shape the future of the composites industry.

Working Groups

Over 40 technical working groups and groups on all relevant topics in the composites industry.


The CU cooperates with important partners in the field of multi-material lightweight design in order to bundle forces and use multiplier effects.


Our sponsors share the passion for innovation with us and support the association in realizing its goals.
