Aluminium Honeycomb 3D (ECM-3D)

Our latest product: ECM 3D

Unlike the classic hexagonal honeycomb the new 3D honeycomb generation can bring in almost any desired shape . Our 3D aluminum honeycomb  offers many advantages compared using the conventional aluminum honeycomb. The excellent ductility in all directions allows tight radius or greater thicknesses of honeycomb slices without the risk of structural damage. Furthermore our groundbreaking cell geometry allows small cell sizes with almost the same density, compressive and shear values ​​compared to classic hexagonal cell geometry. The 3D honeycomb can be used with the out-of-autoclave process. This kind of processing allows a variety of combinations of materials, cell sizes and densities.

Currently, the following honeycomb types are available: ECM 3D 6.4-88 (aluminum 3003 with zirconia coating)

Other cell sizes and densities are available on request.

Friction Stir Welding (FSW)

Friction Stir Welding (FSW) joins two parts with a specially shaped, rotating tool.

Due to rotation and pressure of the tool frictional heat is produced and the parts soften plastically in the area of the rotating tool without reaching the melting point.

The pin of the tool immerses into the malleable material of the parts and produces by its rotation and shape a homogenous blend along the joining line. The shoulder of the tool forms and smoothes the welding line with only a marginal ridge.

After cooling there is a solid phase joint of the two parts. The process does not need filler wire, welding flux or gas shielding and produces a sealed weld without porosity and without inclusions.

Autoclave

Our autoclaves are used for thermal treatment of fiber composite materials in overpressure range.

The thermal treatment of the substances happen in batches because of the typically occurring sealing against the surrounding atmosphere.

The high pressure inside the autoclave is used to compress the individual laminate layers. Generally, the component is simultaneously evacuated in order to completely remove excessive air from the fiber composite.

EURO-COMPOSITES® currently has two autoclaves in operation:

ø 2000 x 6000 mm (6 bar) respectively ø 3000 x 8000 mm (8 bar), with a 24-point respectively 40-point vacuum measuring system and curing temperatures of 180 ° C (standard) up to a maximum of 250 ° C.

Resin Transfer Molding (RTM)

For larger series or components with double-sided decorative surfaces the resin transfer process is best suited.

For larger series or double-sided decorative surfaces the Resin Transfer-Molding (RTM) process is well suited. Massive closed mold and counter-mold system are used as the resin is introduced under pressure into the mold system.

This process pays off for high quality parts and / or components, which are produced in larger quantities.

Resin Infusion

Infusion technology for the serial production.

Resin Infusion is used preferably for complex formed sandwich structures or laminates with only one visible side.

EURO-COMPOSITES® uses different infusion techniques with molds and vacuum foil as counter-molds. Components produced with resin infusion gives the advantage of unlimited selection of materials (like  types of fibers, weaves, clutches, etc.) as well as resin systems . This process brings much more flexibility regarding shape, mechanical, thermal and other properties. Furthermore this process also involves a certain independence in to the availability of prepregs.

The resin infusion technique is suitable for small to medium-sized series.

Honeycombs

In addition, we have developed a novel, perforated aramid honeycomb, which provides venting of the cells with minimal loss of mechanical properties. The perforation of all honeycomb cell sizes and thicknesses is intended for the aviation and space application.

FSW products

FSW (Friction Stir Welding) is an innovative low-temperature welding process. Due to rotation and pressure of a tool frictional heat is produced and the parts soften plastically in the area of the rotating tool without reaching the melting point thereby joining the parts.

FSW allows light weight solutions, that contrary to conventional products still allow the customer to apply many processing and treatment technologies like welding, cathodic bath coating, powder coating, etc.

Single extruded profiles are used to weld together larger structures. This technology offers big advantages as a cost-effective process in cases where large extrusions with thin walls or an asymmetrical design need to be manufactured.

With our modern double-head welding unit we can produce large-format panels with dimensions of 3000 x 13540mm. Due to the single-step welding of both sides a flatness of 2mm per running meter is possible.
