The present invention relates to the use of hydrophopic polyols for producing fiber composite components on the basis of a polyurethane/polyisocyanurate reaction mixture, to a method for producing composite components and to the composite components as such. The method according to the invention is particularly economical in terms of saving material and time costs and the composite components obtained are characterized by excellent visual and material properties.

Composite components on the basis of hydrophobic polyols

The invention relates to foam materials that are resistant to high temperatures, to the production of same from aromatic polyisocyanates and polyepoxides, and to the use of said foam materials.

Foam materials resistant to high temperatures

The present invention relates to storage-stable prepregs (preimpregnated fibers) on the basis of lightfast, low-viscous polyurethane systems with an increased characteristic number and flat fiber composite components (molded bodies; composite compounds) produced therefrom, which can be obtained by methods of impregnation of, for example, woven fabrics and laid scrims, and to a method for the production thereof. The polyurethane system can comprise a reaction product of a reaction mixture of an isocyanate component and a polyol formulation. The isocyanate component comprises an organic isocyanate. The polyol formulation comprises a polyol component, a dianhydrohexitol, a latent catalyst, and optionally auxiliaries and/or additives.

Lightfast polyurethane prepregs and fiber composite elements produced therefrom

The invention relates to prepregs and to a method for producing storage-stable polyurethane prepregs (pre-impregnated fibers) using polyols with a high content of secondary hydroxyl end groups, to composite fiber components (composite components) which are produced from the prepregs and which can be obtained by impregnating fiber-shaped materials such as woven fabrics and fleece, and to a method for producing said composite fiber components.

Polyurethane prepreg and composite fiber element produced therefrom

The present invention fiber composite components obtainable, for example, by impregnating fibers with a reactive polyurethane resin mixture of polyisocyanates, polyols, thermo-latent catalysts and optionally additives, and to a method for the production thereof.

Composite fibre components and the production thereof

The invention relates to a storage-stable resin film based on polyurethane systems having a very high characteristic number and fiber-composite components (composite components, molded bodies) produced therefrom by compressing the resin film, in combination with fiber-reinforced materials such as woven fabrics and fleece, at high temperatures and under pressure, and to a method for the production thereof.

Storage stable resin films and fibre composite components produced therefrom

The invention relates to storage-stable prepregs (preimpregnated fibers) based on low-viscosity polyurethane systems having a very high characteristic number and flat fiber composite components (molded bodies; composite components) produced therefrom, which are obtained due to an impregnation method of fiber reinforced materials such as woven fabrics and fleece, and to a method for the production thereof.

Storage-stable polyurethane-prepregs and fibre composite components produced therefrom

The invention relates to polyurethane casting resins for producing polyurethane potting compounds, which can be obtained from a reaction mixture of polyisocyanates, polyepoxides, polyols, latent catalysts and optionally additives. The invention also relates to a method for producing said compounds.

Polyurethane casting resins and potting compounds produced therefrom

The invention relates to fiber-composite components, obtained for example by impregnating fibers with a reaction resin mixture of polyisocyanates, polyepoxides, polyols, latent catalysts and optionally additives. The invention also relates to a method for producing said components.

Fibre-reinforced composite components and production thereof

The present invention relates to high-value polyurethane (PUR) and polyurethaneurea elastomers, which can be processed in a particularly simple manner by use of low-viscosity prepolymers based on naphthalene 1,5-diisocyanate, and to a process for production thereof.
