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 present invention relates to a drapable core material suitable for use in closed mould systems, hand lay-up applications and/or spray-up applications, preferably having a compression-resistance of more than 30% at 1 bar pressure, wherein core material is based on at least one fibrous web containing a foam-structure within the web, said foam-structure being formed of a plurality of members, which members are separated from each other by channels which channels are permeable to resin. The invention further relates to a laminate comprising such core material, a method for manufacturing the core material and a method for manufacturing such laminate.
