The invention relates to a method for connecting two fibre-reinforced plastic components, comprising the following steps: producing a first fibre-reinforced plastic component, wherein a fabric made of fibrous matting is provided, which is impregnated with a resin-curing agent mixture, which is then subsequently cured, wherein the part of the surface of the first fibre-reinforced plastic component, which is to be later adhered to the second fibre-reinforced plastic component (hereinafter also referred to as joining surface), is masked with an adhesive strip before the impregnation of the fibrous matting with the resin-curing agent mixture; producing a second fibre-reinforced plastic component using the above steps, wherein the part of the surface of the second fibre-reinforced plastic component, which is to be later adhered to the first fibre-reinforced plastic component, is also masked with an adhesive strip before the impregnation of the fibrous matting with the resin-curing agent mixture; removing the adhesive strips from the two finished fibre-reinforced plastic components; bringing the two joining surfaces in contact; introducing a resin-curing agent mixture between the two joining surfaces; curing the resin-curing agent mixture, wherein the adhesive strip has a carrier film, on one side of which an adhesive mass, in particular self-adhesive mass is applied, and wherein the carrier film consists of fluoropolymers, polyethylene polymers, undrawn polypropylenes or of metal, and the adhesive mass is an acrylate or silicon adhesive mass.

Method for joining two fibre-reinforced plastic components

The invention relates to a method for the production of a layered or stacked inorganic/organic composite material, a predominantly inorganic material being provided and a polymer material being provided, characterized in that the predominantly inorganic material has a glass transition temperature or melting temperature lower than 500&#xb0; C., that the predominantly inorganic material and the polymer material are each molten, and that the predominantly inorganic material and the polymer material are coextruded from the melt and thus form the composite material.

Method for the production of a layered or stacked inorganic/organic composite material

The present invention relates to a film arrangement featuring a layer A and a layer B, layer A and layer B being of polymer-based formation, and layers A and B being unstretched. It is proposed that layer A and layer B have different tension sets from one another, that layer A has a tension set of at least 60% and that layer B has a tension set of not more than 50%.

Film arrangement

Liner comprising a film which comprises oriented polypropylene having a flexural modulus of at least 1400, preferably at least 2000 MPa, a release coating being applied on at least one of the two outer sides of the film.

Liner and also the use thereof

The invention relates to a film, in particular for an adhesive tape, characterized in that the film contains at least one homopolymer, copolymer, or terpolymer of the propylene and fibers and is monoaxially stretched in the longitudinal direction, wherein the elongation ratio is preferably at least 1:8 and particularly preferably at least 1:9.5.
