April 2019 marks another breakthrough for carbon fiber spar caps produced in VAP® infusion

With the process development from COMPOSYST GmbH, a blade manufacturer in China successfully finished the production of an 87,5 m long carbon fiber spar cap, the longest and widest one made in infusion so far.

The spar cap was infused in VAP® technology with COMPOSYST’s VAP® membrane which enables degassing of the resin during the entire infusion and eases resin distribution throughout the entire part. Furthermore, the double-chamber system created by the VAP® infusion system makes it possible to precisely adjust the amount of resin allowed into the part. This fact, together with the characteristically homogeneous pressure distribution of a VAP® infusion, results in an accurately determined fiber volume fraction that is constant throughout the entire part length.

For the infusion process to run smoothly, the fibre architecture of the preform –especially with regard to its permeability– also plays a decisive role. COMPOSYST worked in close collaboration with the textile experts at SAERTEX in order to select the unidirectional non-crimp fabric with increased z-permeability that was used in this project.

The infusion process itself took less than 2 hours –a record spar cap in record time! After demolding, all parties involved were pleased to inspect a spar cap of virtually perfect built quality.

At the end of the day, VAP® technology is reliable, easy to implement and made this challenging infusion possible whilst delivering a defect-free part.

The DLR Center for Lightweight Production Technology turns 10

On May 15th 2019 the DLR Center for Lightweight Production Technology (ZLP) in Augsburg celebrated its 10-year anniversary. High-ranking guests from different backgrounds (politics, industry and research) took part in the festive colloquium.

“The Center for Lightweight Production Technology has established itself as a strong research partner – not only at regional and national levels, but also within the international sphere – and we are proud of that achievement. Thanks to the consistent digital use of data and the implementation of AI tools, the ZLP Augsburg also opens up new opportunities for lightweight construction, enabling DLR to further expand its position as a technology driver in the future.”

said Klaus Hamacher, Vice Chairman of the Executive Board.

Our VAP® membranes have been granted authorisation to use the STANDARD 100 by OEKO-TEX® mark.

The results of the inspection made according to STANDARD 100 by OEKO-TEX®, Appendix 4, product class II have shown that VAP® membranes meet the human-ecological requirements of the STANDARD 100 by OEKO-TEX® presently established in Appendix 4 for products with direct contact to skin.
