The present invention relates to a battery housing and to its use in electric vehicles. The battery housing includes at least a cover and a floor which are joined to one another and the cover is joined to the vehicle body or a part of the vehicle body forms the cover. The floor faces away from the vehicle body, is obtained by pultrusion, and is made of thermosetting plastic obtainable from a reactive resin mixture and reinforced with endless fibers, wherein the fibers run transversely to the direction of travel of the vehicle.

Battery housing and its use in electric vehicles

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.

Lightfast polyurethane prepregs and fiber composite elements 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 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.
