Described herein is a process for preparing a polyurethane-type fiber composite material, said process including (a) di- and/or polyisocyanates, (b) compounds having isocyanate-reactive hydrogen atoms, (c) compounds including at least one carbon-carbon double bond, (d) optionally a catalyst to hasten a urethane reaction, (e) optionally a free-radical initiator, and (f) optionally further auxiliary and added-substance materials, being mixed into a reaction mixture—with concomitant wetting of a fiber material—and cured. Also described herein is a polyurethane-type fiber composite material obtainable by a process described herein and also to a method of using the polyurethane-type fiber composite material as a structural component part.

Polyurethane material with a high temperature resistance

Described herein is a compact polyurethane having a density of ≥850 g/l, obtainable by reacting at least the components: Also described herein are a process for producing such a compact polyurethane and compact polyurethanes obtainable by this process. Also described herein is a method of using such a compact polyurethane for the production of a fiber composite. Also described herein are a corresponding fiber composite material and a process for producing such a fiber composite.

Compact polyurethane

The present disclosure relates to processes for the production of a polyurethane material, where (a) di- and/or polyisocyanates, (b) compounds which have hydrogen atoms reactive toward isocyanate groups and which do not include compounds having carbon-carbon double bonds, (c) compounds including at least one carbon-carbon double bond, (d) optionally catalyst that accelerates the urethane reaction, and (e) optionally other auxiliaries and additives are mixed to give a reaction mixture and the mixture is hardened at temperatures above 120° C. The present disclosure further relates to a polyurethane material obtainable by this process, and also to the use of the polyurethane material, in particular of a polyurethane fiber-composite material as structural components.

Polyurethane-based polymer material having excellent resistance to heat distortion and elongation at tear

An apparatus for impregnating fiber structures with a matrix material includes a lower part having a bath for receiving the matrix material and a draining unit. The draining unit includes a wiper having a wiping edge, over which the impregnated fiber structure is guided during operation, and a surface inclined in the direction of the bath, by which matrix material draining from the fiber structure can return into the bath. The draining unit includes a cover on which a deflection unit, by which the fiber structure is pressed into the bath when the cover is mounted, is mounted. When the cover is mounted, a gap is formed between the cover and the lower part on the sides by which the fiber structure is guided into the apparatus and emerges from the apparatus. A method for impregnating fiber structures with a matrix material is also disclosed.

Device and method for impregnating fiber structures

Described herein is a device for impregnating individual fibers, individual threads, or individual rovings with a matrix material, including a porous material that is soaked with the matrix material, and a metering installation for metering matrix material into the porous material, where an installation by way of which the individual fiber to be impregnated, the individual thread to be impregnated, or the individual roving to be impregnated can be pressed against an end face of the porous material is included, or where the porous material is received in a sleeve and the individual fiber, the individual thread, or the individual roving can be guided through the porous material in the sleeve. Also described herein is a method for producing a component from impregnated individual fibers, individual threads, or individual rovings.

Device and method for impregnating individual fibers, individual threads, or individual rovings

The present invention relates to polyurethanes obtained by mixing to give a reaction mixture of (a) polyisocyanate, (b) polymeric compounds having groups reactive toward isocyanates, (c) catalysts comprising incorporable amine catalysts, (d) phosphoric esters, polyphosphates, phosphonic esters, and/or phosphorous esters, and optionally (e) blowing agents, (f) chain extenders and/or crosslinking agents, and (h) auxiliaries and/or additives, and completing the reaction of the reaction mixture to give the polyurethane. The invention further relates to a process for producing these polyurethanes and to their use in automobile interiors.

Polyurethane foams comprising phosphorus compounds

A process for producing high resilience flexible polyurethane foams. The process includes forming a mixture of (a) isocyanate prepolymer, (b) polymeric compounds having isocyanate-reactive groups, (c) castor oil, (d) optionally chain-extending and/or crosslinking agents, (e) catalysts, (f) blowing agents, and optionally (g) additives, and reacting the mixture to form the flexible polyurethane foam. More than 5 wt % of (c) is used, based on the total weight of components (b) to (g), and (a) is obtained by mixing diphenylmethane diisocyanate (a1) and polyol 1 (a2) and also optionally further polyols, chain extenders and/or crosslinkers, where (a2) includes a polyalkylene oxide polyol having a hydroxyl number of 30 to 60, an average functionality of 2.3 to 3.2 and a propylene oxide fraction, based on the alkylene oxide content, of 70 to 100 wt %. A polyurethane foam obtained by the process, and the use of such a foam as an auto seat.

High resilience polyurethane foams comprising castor oil

Invention relates to a process for producing viscoelastic flexible polyurethane foams by reacting a) polyisocyanates with b) compounds having at least two hydrogen atoms which are reactive toward isocyanate groups, wherein as b) a mixture of bi) from 25 to 70% by weight of a hydroxyl-comprising natural oil or fat or a reaction product of a hydroxyl-comprising natural oil or fat with alkylene oxides, bii) from 3 to 30% by weight of at least one polyether having a hydroxyl number of from 100 to 800 mg KOH/g and a functionality of 3-5 selected from the group consisting of polyether prepared by addition of alkylene oxides onto an amine, biii) 20-50% by weight of at least one polyether alcohol having a hydroxyl number of from 10 to 80 mg KOH/g and a functionality of 2-5, where the proportion of ethylene oxide is 5-25% by weight, based on the weight of the polyether alcohol, and at least part of the ethylene oxide is added on at the end of the polyether chain, biv) &#x3e;0-8% by weight of at least one polyether alcohol having a functionality of 2-4, a hydroxyl number of 15-60 mg KOH/g and a content of ethylene oxide of &#x3e;50% by weight of the polyether alcohol is used.
