Our manufacturing range involves a variety of CFRP lamination approaches.

Lathing and milling enables us to have our own delay-free toolmaking.

Precision is also provided with our internal dynamic balancing bench.

Altogether our manufacturing offers ideal prerequisites for customised projects.

Wet Lay up Process

The answer to the question of how to achieve an excellent price vs quality ratio is the classic hand laminate. Due to our long-standing experience in dealing with hand laminates and our highly-skilled workforce we can offer you steady quality standards with a high fibre volume ratio and perfect optics.
We refine such parts by using 1k or 3k CF-fabrics or glass fabrics with aircraft certification. In combination with the aviation approved resin system, which we use as a matrix, our approach to wet layup technology allows us to offer you first class components.

-processing of carbon fibre, fibreglass or aramid fibre

-optionally aviation approved resin system, high Tg resins

-component sizes of a length of up to 1.5m

Vacuum Bagging

Highest laminate quality and a low investment sum do not necessarily have to exclude each other. We apply the vaccum method in order to increase the fibre volume ratio in our components and keep it at a certain level in order to create sandwich laminate with a high level of stiffness.

-high fibre volume ratio

-components stiffened with honeycomb and rigid foam

-aviation approved resin system opionally, high Tg resins

-component sizes of up to 1.5m

Wet Compression

At Schübeler Technologies we design and manufacture high-precision molds by means of in-house CNC milling. This is how we can keep the costs low while maintaining a high quality standard. Wet pressing is the perfect choice for thin-walled components with a high fibre volume ratio and also for fibred-filled volumes and hollow spaces.The resulting laminates are characterised by extraordinary high surface quality. Like all lamination approaches for wet pressing only high-quality CF- and glassfibres and aviation approved resin systems are used. If there are special requirements we use heat-curing epoxy resin enabling us to create components with up to 180°C Tg.


-processing of carbon fibre, fibreglass or aramid fibre

-aviation approved resin systems

-low wall thicknesses of 0,1mm at a high fibre volume ratio

-components possible with up to 180°C Tg

-component sizes of up to 1m

 

Prepreg

Within the innovative manufacturing process with pre-impregnated semifinished prepreg we can reach laminates with highest fibre volume ratios. The resulting components which can assume almost every shape due to heated molds are temperature-resistant up to 180°C. These oustanding characteristics make prepreg laminates an optimum choice for any structures which require moulds. We are able to design and manufacture the specific prepreg moulds, like the moulds for wet-pressing in-house. That is why we can realise your project at an excellent cost-benefit ratio maintaining our high quality standards.


-fast serial production at enormous component quality

-components with Tg of up to 180°C

-very light and high-strength components

-wide range of component sizes

Vacuum Infusion

For constant quality or bigger components vacuum infusion is an economically reasonable technique. The laminates are characterised by a high fibre to volume ratio and can be produced at a high quality due to the self-infusion approach.


-high fibre volume ratio

-steady high quality level

-aircraft certified resin system

-Tg up to 140°C

Dynamic Balancing

We balance the rotating components of our machines on a two-level vertical balancing machine. The smallest measurable unbalance is smaller than 0,5gmm. We can balance rotors of up to 30kg and of a maximum diameter of 380mm. The unbalance position is shown by means of laser projection. Depending on the design of the rotor balancing will either be effected via material feed or material removal. For special requirements the turbomachine which is being assembled later additionally undergoes a field balancing procedure by means of an acceleration sensor. That way we can also discover and eliminate even marginal assembly-related inaccuracies.

 

Joining Technology

In order to achieve high quality we put emphasis on joining processes especially for rotating parts. We use a range of techniques from classic adherence to hybrid processes. Our collaboration with the LWF (Laboratory of Material and Joining Technology) of the University of Paderborn enables us to achieve individual and approved solutions.

Lathing and Milling

In our internal toolmaking we work with two CNC milling machines with three axis each. Your tool is generated as master pattern with the CNC technique and can be easily remolded as FRP tool.That way freeform surfaces with work piece sizes of up to 1.8 x 0.9 x 0.25m are reproduced.
