- pultrusion processes by application of the solution in a roll mill or by means of a hot doctor blade , or other procedures are performed.
- the invention also relates to the use of prepregs, in particular with fiber-shaped carriers made of glass, carbon or aramid fibers.
- the invention also provides the use of the prepregs according to the invention, for the production of composites in boat and shipbuilding, in aerospace engineering, in the automotive industry, for two-wheelers, preferably motorcycles and bicycles, in the areas
- Power generation plants eg. B. for rotor blades in wind turbines.
- the invention also relates to the composite components produced from the prepregs according to the invention.
- the finished composite components produced from the prepregs according to the invention have a colored, matt, particularly smooth, scratch-resistant or antistatically finished surface.
- Type I is a canvas E-glass fabric 281 L, article No. 3103 of the company "Schlösser &Cramer"
- the fabric has a basis weight of 280 g / m 2 .
- a reactive polyurethane composition having the following formulation was used to make the prepregs and composites.
- Example 1 Formulation [Variant I]
- this reactive polyurethane composition can be used to prepare the prepregs depending on the manufacturing method.
- Polyurethane composition can then be used after milling to prepare the prepregs after the powder impregnation process.
- the homogenized melt mixture produced in the extruder can be used directly.
- a highly reactive polyurethane composition having the following formulation was used to make the prepregs and composites.
- VESTAGON BF 9030 (uretdione group-containing 33.05
- Polyester resin component b) Polyester resin component b)), DIC company
- the fixing of the films takes place directly after the melt impregnation of the fibrous carrier, wherein care is taken that the, when fixing the film on the prepreg existing temperature of the impregnated matrix material between 5 and 20 ° C above the glass transition temperature of the film, so Adhesion between film and prepreg when pressed.
- the films used are, for example, FLUOREX 2010 (ABS support material) (Soliant) or SENOTOP films (Senoplast GmbH).
- the Senotop film itself consists of several coextruded layers of thermoplastic material and is characterized by a Class A surface. DSC measurements
- the storage stability of the prepregs was determined on the basis of the glass transition temperatures and the reaction enthalpies of the crosslinking reaction by means of DSC investigations.
- the cross-linking ability of the PU prepregs is not affected by storage at room temperature for a period of 7 weeks.
- the composite components are produced by means of a pressing technique known to the person skilled in the art on a composite press.
- the homogeneous prepregs produced by means of direct melt impregnation were pressed on a table press into composite materials.
- This tabletop press is the Polystat 200 T from Schwabenthan, which presses the prepregs at temperatures between 120 and 200 ° C into the appropriate composite plates.
- the pressure is varied between normal pressure and 450 bar.
- dynamic compression ie changing pressurizations, can prove advantageous for the wetting of the fibers.
- the temperature of the press is increased from 90 ° C during the Aufschmelzphase to 1 10 ° C, the pressure is increased after a melting phase of 3 minutes to 440 bar and then dynamically (7 times with each 1 minute duration) between 150 and 440 bar varies, the temperature is continuously increased to 140 ° C. Subsequently, the temperature is raised to 170 ° C and at the same time the pressure at 350 bar until removal of the composite component from the press after 30 minutes height, is held.
- Fiber volume fraction of> 50% are examined with regard to the degree of hardening (determination by DSC).
- the determination of the glass transition temperature of the cured matrix shows the progress of the crosslinking at different curing temperatures.
- the crosslinking is complete after about 25 minutes, in which case no reaction enthalpy for the crosslinking reaction is detectable any more.
