Abstract: The invention relates to a process for producing storage-stable polyurethane prepregs and mouldings produced therefrom (composite components). For production of the prepregs or components, for example, (meth)acrylate monomers, (meth)acrylate polymers, hydroxy-functionalized (meth)acrylate monomers and/or hydroxy-functionalized (meth)acrylate polymers are mixed with non-(meth)acrylic polyols and with uretdione materials. This mixture or solution is applied to fibre material, for example carbon fibres, glass fibres or polymer fibres, by known methods and polymerized thermally, via a redox initiation or with the aid of radiation or plasma applications. Polymerization, for example at room temperature or at up to 80° C., gives rise to thermoplastics or thermoplastic prepregs which can subsequently be subjected to a forming operation.

Abstract: The invention relates to a process for producing semi-finished composites and composite components. For production of the semi-finished products or components, (meth)acrylate monomers, (meth)acrylate polymers, polyfunctionalized (meth)acrylates, hydroxy-functionalized (meth)acrylate monomers and/or hydroxy-functionalized (meth)acrylate polymers are mixed with di- or polyisocyanates or with uretdione materials. This liquid mixture is applied by known processes to fibre material, for example carbon fibres, glass fibres or polymer fibres, and polymerized with the aid of a first temperature increase or of a redox accelerator or by means of photoinitiation. Polymerization, for example at room temperature or at up to 120° C., gives rise to thermoplastics which can still be subjected to a forming operation. The hydroxy-functionalized (meth)acrylate constituents can subsequently be crosslinked in a press with isocyanates or uretdiones already present in the system at a second temperature at least 20° C.

Abstract: The invention relates to a process for producing a separator comprising the steps of: providing a sheetlike porous substrate, a solvent, ceramic particles and an adhesion promoter; preparing a slip by mixing the solvent, the adhesion promoter and the ceramic particles; coating the substrate with the slip and thermally drying the coated substrate to obtain the separator. The problem addressed is that of specifying a process useful for producing separators having a higher ceramic content. The problem is solved when the solvent used is a mixture of water and at least one organic component; the adhesion promoter used is a mixture of silanes and at least one thermally crosslinkable acrylic polymer; the slip is admixed with a carboxylic acid preparation and also with a defoamer component free from silicone oil.

Abstract: The invention relates to a method for the production of storage-stable prepregs and moulded objects produced therefrom (composite components). The composition used according to the invention for the production of the prepregs here contains A) monomers, in particular (meth)acrylates and/or styrene, B) at least one (meth)acrylate with a residue which contains a conjugated diene, C) a crosslinker having at least two dienophilic groups, and D) at least one suitable initiator. Alternatively, instead of or additionally to the components B) and C), the composition can contain a product C? of a Diels-Alder reaction of the two components B) and C).

Abstract: The invention relates to a perforated polymer film with porosity P from 30% to 50% and with an arrangement of perforations which is characterized by the perforation shape, the ratio of the semiaxes of the perforations, the orientation of the perforations, and the regular arrangement of the perforations, where the longitudinal tensile stress that the polymer film withstands without breaking is greater than that for identical porosity and any other arrangement of perforations which differs in at least one feature.

Abstract: The present invention relates to a floor cleaning tool. In one embodiment the floor cleaning tool comprises a backing and a handle. The backing comprises a first surface and a second surface. The handle is attached to the second surface of the backing apparatus. The backing has a generally triangular perimeter having a first edge, a second edge, and a third edge. A portion of the first edge is curved and a portion of the second edge is curved. The first edge and second edge meet at a leading point. The third edge is concave. The floor cleaning tool is capable of supporting a wipe.

Abstract: A handle assembly for use with a fibrous cleaning pad. The handle assembly includes a generally rigid first member including a first insertable portion, and a handle portion with a first end of the handle portion fixed to a second end of the first insertable portion and a manually engageable part adjacent a second opposite end of the handle portion. The handle assembly also includes a second member including a second insertable portion, and an actuation portion having a first end fixed to a second end of the second insertable portion. A first end of the second insertable portion opposite the actuation portion is pivotally mounted on a first end of the first insertable portion opposite the handle portion for relative movement of the insertable portions by manual manipulation of the actuation portion between a diverging position with outer surfaces of the insertable portions diverging from their first ends, and an adjacent position with the outer surfaces of the insertable portions generally parallel.
