Abstract: The invention is directed to a core material, suitable for use in a closed mold system, based on at least one fibrous web containing a foam-structure within the web, said foam-structure being formed of a plurality of members that are separated from each other by channels, wherein said core material has a compression-resistance of greater than 40% at a pressure of 4 bar and at a temperature that is greater than or equal to 80° C.

Abstract: The invention is directed to a flexible protective sheet. In a first aspect, the invention provides a flexible protective sheet comprising a carrier and a foam-structure, wherein said foam-structure is composed of a plurality of expanded foam units attached to said carrier sheet.

Abstract: The invention is directed to a core material for closed or open mould systems, to a process for preparing a core material, to a laminate comprising the core material, to a process for preparing a shaped article, to a shaped article, and to the use of said article. The core material of the invention comprises at least one fibrous web containing a foam structure within said web, said foam structure being formed of a plurality of members, wherein said members are separated from each other by channels that are permeable to resin, a binder, and a network of an electrically conductive material.

Abstract: The invention is concerned with a fibrous web for making a shaped article reinforced with fibrous webbing by impregnating the web with a liquid resin and a hardener therefor, wherein said web comprises indicating means, which indicate the impregnation of the web with said liquid resin and said hardener.

Abstract: The invention relates to a cable tape, based on at least one fibrous web, in which fibrous web at least 0.5% by weight, calculated on the weight of the cable tape, of thermoplastic microspheres which may or may not be partly or wholly expanded and, if desired, an effective amount of a water-swelling powder is incorporated, and to a method for the manufacture of such a tape and to cable manufactured using the tape.

Abstract: The invention is concerned with a core material suitable for use in closed mould systems, based on at least one fibrous web containing a foam-structure within the web, said core material having a compression-resistance of greater than 90% at 1 bar pressure, and a permeability for resin of more than 5×10−9 m2.

Abstract: The invention is concerned with a fibrous web for making a shaped article reinforced with fibrous webbing by impregnating the web with a liquid resin and a hardener therefor, wherein said web comprises indicating means, which indicate the impregnation of the web with said liquid resin and said hardener.

Abstract: The invention relates to the use of an assembly comprising at least one non-conductive or substantially non-conductive carrier material and at least one conductive fiber web which has been provided on at least one side of the carrier material, with fibers of the conductive web having been brought into electrically conductive contact, through the carrier material, with the other side of the carrier.

Abstract: The use of a fibrous web provided with microspheres disposed mainly within said web and arranged in a pattern in which areas of the web which contain microspheres and separated from each other by areas which contain virtually no microspheres, for making an article of manufacture reinforced with fibrous webbing by impregnating the web with a liquid resin and a hardener therefor.A shaped article of manufacture comprising a bonded fibrous web as described hereinabove, provided with expanded microspheres, said fibrous web having been impregnated with a mixture of a liquid resin and a hardener therefor, cured after being shaped, as well as a method of making a fibrous web incorporating microspheres, which is characterized in that microspheres not yet expanded are pressed into the fibrous web by means of a foam paste.

Abstract: The invention relates to a method of printing a substrate in a pattern with a viscous mass in the form of a foam using a screen printing machine.In order to provide new structures, especially in combination with the printing of fibrous webs, the invention is characterized in that the foam used has meta-stable foam properties. The structure of the foam is maintained intact during transfer and subsequent treatments.
