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.

VAP® technology for NEXICOS prototype from Premium AEROTEC

Nexicos

Premium AEROTEC GmbH recently demonstrated its own production expertise and the strengths of VAP® membrane-assisted low pressure infusion at the unveiling of the prototype of a civilian helicopter fuselage section in its NEXICOS project. Using VAP® membrane systems, the aerostructure supplier had fabricated the complex fuselage barrel in a single go, complete with integrated stringers, local reinforcements and window frames. As it reports, the Vacuum Assisted Process not only enabled automation of various process steps but also delivered significant mould-making flexibility, thus smoothing the way further for scaling up production of the part to the industrial level. The VAP® approach also yielded cost savings of 30 percent over comparable prepreg structures.


Diamond Aircraft Industries signed VAP® licensing contract

Ila 2010 Daimond The VAP contract was signed by Airbus CTO Jean Botti; Christian Dries, CEO of Diamond Aircraft; and Dr. Rolf Wirtz, the CTO of Airbus Defence & Security

The technology licensing contract with Diamond Aircraft Industries enables this manufacturer to utilise Airbus’ patented Vacuum Assisted Process (VAP®) and VAP® - membrane systems by Trans-Textil in the production of its full range of general aviation and personal jet aircraft. VAP® allows composite structures to be manufactured without the use of traditional autoclaves, and provides high quality parts that are more cost effective to produce while also improving production flexibility and reducing throughput times.

Diamond Aircraft Industries already has successfully demonstrated the advantages of VAP® in proof-of-concept development work for its D-JET private jet, and is expected to apply this process across its product line of general aviation aircraft, which are produced at the company’s facilities in Austria and Canada.

VAP® Vacuum Assisted Process

The 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 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 VAP® 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

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 VAP® membrane systems with various resins systems all the way up to the high-temperature level is tested in realistic conditions.

Patented VAP® resin infiltration technology

VAP® has long been proving its worth, making it an established method for the production of high-quality lightweight components for use in aviation and wind power as well as in the transport sector and other industrial mass production applications. In the interests of VAP® users and their customers, the patented VAP® process as well as VAP® membrane systems and related components are protected in all application fields by extensive international industrial property rights held by Airbus and Trans-Textil. A license contract provides entitlement to use of patented VAP® technology.

VAP® membrane systems, support and training

The partners in the VAP® Alliance offer not only various production auxiliaries but also professional support in the areas of engineering, application technology and fabrication. They also accompany verification, qualification and acceptance processes as well as series and contract production, and furnish instruction and training in the use of membrane-assisted vacuum infusion according to the VAP® Vacuum Assisted Process.
