VAP® Membrane System CS / E: distinctive print image documents environmental performance and
"Quality from Germany" 


The patented VAP® membrane system CS/E has been specially developed for use in VAP® technology. In addition to its reliable process performance and compatibility with various resin systems, it is characterized by its high standards of human ecological safety, which is attested by certification to the Standard 100 by Oeko-Tex®. Quality and environmental performance is now also documented by the distinctive and process-conforming print on the textile carrier side.

VAP® 3D ready-mades for large aerospace structures

case of a full-scale final-stage booster demonstrator of ariane 6 launcher

VAP® 3D ready-mades developed and produced by Trans-Textil together with the Center for Lightweight Production at the German Aerospace Centre (DLR-ZLP) in Augsburg have again enabled the two partners to demonstrate the potential of prefabricated material kits adapted to component form. As part of the "Optimized vacuum bagging for CFRP rocket booster cases" project, DLR and Trans-Textil recently implemented the concept of instant-use multifunctional textile auxiliary packs in the case of a full-scale final-stage booster demonstrator measuring 3.4 metres in diameter and 6 metres in length for the Ariane 6 launcher.    

Special joining techniques made it possible to successfully adapt the central process component – digitally computed pattern pieces of the VAP® membrane system – to the complex component geometry with its cylindrical and curved sections while ensuring high accuracy of fit in the process. Thanks also to integrated resin feeds for out-of-autoclave infusion and an application-oriented packaging design, DLR and Trans-Textil have thus achieved the ideal prerequities for reproducible, simiplified and thus time-optimised deployment of fabrication incorporating VAP® 3D ready-mades.

VAP® technology for European satellite mission

European Satellite Mission

As of 2021, the MetOp Second Generation A Satellite Mission will be measuring trace gases, ozone and aerosol in the earth's atmosphere, thus contributing to continuous air quality monitoring in particular. In the context of the European Copernicus Programme, the satellite mission will be expanding our planet's extensive climate records in this way. Under contract to the European Space Agency, Airbus Defence & Space GmbH develops and produces carbon fibre-reinforced components for the Sentinel 5 instrument involved, using Trans-Textile's patented aerospace-qualified VAP® membrane system in the process. VAP® technology is thus making a substantial contribution to consistent and high-precision production of the ultralight components.

Solutions adapted to component form

Solutions adapted to component form

As part of the AZIMUT and RoCk projects and working in response to calls for automated and optimized process chains, Trans-Textil and Composyst have developed a new made-to-shape approach especially devised for large aviation structures that need to be fabricated in one integral process. Starting with the geometry data of the Airbus A350 pressure bulkhead, this involved compiling the layers in the VAP® process lay-up into a VAP® 3D material kit made up of instant-use textile auxiliaries that have been tailored to the precise shape of the component mold.

Automated deployment

Automated deployment

The large-scale, multi-layer made-to-shape VAP® 3D solutions come with robot grip straps for swift, automatic and precisely-positioned layer stacking in the mold. This almost entirely eliminates the need for laborious cutting work and other preparatory tasks such as joining, positioning, repositioning and fixing the layers by hand. The VAP® 3D material kit has already proved its worth in a trial involving a full-size Airbus A350 pressure bulkhead in the RoCk Projekt.

VAP®-produced carbon chassis

Gokart Team

The carbon chassis of an electrically-powered go-kart has been produced entirely in VAP® technology by the StudKart student initiative at Stuttgart University. Thanks to use of a VAP® membrane system by Trans-Textil, the complex geometry of the CFRP sandwich structure frame was infused without occurrence of any dry spots. The interdisciplinary StudKart work group makes use of the latest developments in the electromobility field and develops innovative ideas of its own. Thanks to the hybrid construction of the carbon chassis, a weight savings of 40 percent has been achieved compared to the previous model. The whole project has been conceived and realized by the students at their own initiative.

Efficient wing production in high-end quality


The electric-powered glider ELIAS (Electric Aircraft of IABG ACENTISS) based on the Elektra One Solar, a solar-electric aircraft by PC-Aero GmbH of Nesselwang, has a wingspan of 10.60 m yet weighs a mere 211 kg.

VAP® membrane systems for vacuum infusion

The membrane supported VAP® Vacuum Assisted Process is an advanced process technology based on the classical vacuum infusion techniques used to produce lightweight components out of fibre reinforced polymers (FRP). VAP® technology deploys semipermeable patented VAP® membrane systems for reliable degassing of the matrix material both during and after resin infusion. Thanks to the continual venting of trapped air and reaction gases, vacuum infiltration performed according to the VAP® Vacuum Assisted Process delivers quality components out of carbon fibre composites (CFC), glass-fibre reinforced polymers (GRP), aramid fibre-reinforced polymers (AFP) and other fibre-reinforced composites. Lightweight nil-porosity parts offering a precisely achievable fibre volume content without dry spots are the result. Since the membrane supported VAP® vacuum infusion process lowers costs by reducing the number of rejects and the need for reworking, it is a highly economical lightweight construction method for use in batch manufacturing and series production.

Cost-effective lightweight construction with VAP® vacuum infusion membrane

VAP® membrane systems and production auxiliaries not only deliver high process consistency and predictability but can also be adapted to the component in question for automation of process steps and reduction of handling. The interaction of patented VAP® membrane systems with various resins systems all the way up to the high-temperature level is tested in realistic conditions.
