Pultrudate based on polyurethane and carbon fibers and the production and use thereof.

Pultrudate, production and use thereof

The invention relates to a new polyurethane system which can be advantageously used for the production of large structural components made of fiber composite materials, to the use of said polyurethane reaction system for the production of fiber-reinforced structural components, and to the fiber-reinforced structural components produced using the new polyurethane system.

Polyurethane systems for layer structures in wind turbines

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.

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 foams of high thermal stability, to the production thereof from organic polyisocyanates and polyepoxides, and to the use of the foams.

Foams of high thermal stability

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

A composite member for a vehicle body a method for manufacturing such a composite member, in particular, for a vehicle roof, with a fiber-free outer skin () and a fiber-reinforced support layer (), which is deposited at the inner side of the outer skin in order to support the outer skin. The side of the support layer () that faces away from the outer skin () is provided with a fiber-reinforced reinforcing layer () for reinforcing the support layer. The reinforcing layer has a higher fiber concentration than the support layer.

Composite elements made from polyurethane materials having surfaces consisting of thermoplastic or metallic layers and a process for their production

The present invention relates to plastic moldings that are prepared from optionally filled polyurethanes. The plastic molding of the present invention exhibit high tenacity, flexural strength and heat stability. This invention also relates to a process for the preparation of these plastic moldings and specifically to a process for the production of large parts comprising these plastic moldings.

Plastic moldings from optionally filled polyurethanes and their use

Activators with reduced volatility that are liquid at room temperature are obtained as the reaction product of (A) a secondary amine or primary alcohol having at least one tertiary amine group, (B) a polyisocyanate of the diphenylmethane series having a functionality of from 2.5 to 4.0 and an OH-functional reactive component capable of addition to isocyanate. These activators are useful for the production of polyurethane foams having improved emission behavior.
